AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

This action amends the Qualification Performance Standards (QPS) for flight simulation training devices (FSTD) to provide greater harmonization with international standards for simulation. In addition, the rule adds a new level of simulation for helicopter flight training devices (FTD) and establishes FSTD Directive 1, which requires all existing FSTD airport models that are beyond the number of airport models required for qualification to meet specified requirements. The intended effect of this rule is to ensure that the flight training and testing environment is accurate and realistic. Except for the requirements of FSTD Directive 1, these technical requirements do not apply to simulators qualified before May 30, 2008. This rule results in minimal to no cost increases for manufacturers and sponsors.

DATES:

These amendments become effective May 30, 2008.

IV. The Amendment

I. Background

On October 30, 2006, the FAA published Title 14, Code of Federal Regulations, Part 60, with an effective date of October 30, 2007 (71 FR 63392). The intent of the rule was to promote standardization and accountability for FSTD maintenance, qualification, and evaluation. The regulation codified the standards contained in advisory circulars (ACs) and implemented the Qualification Performance Standards (QPS) appendices format. The QPS appendices allow regulatory requirements and corresponding information to be presented in one location. The QPS appendices format promotes ease of use and greater insight about the FAA's intent behind the regulation and the required and approved methods of compliance. On October 22, 2007 (72 FR 59598), the FAA delayed the effective date of part 60 to coincide with the effective date of this final rule, which revises the appendices of part 60 that were originally published on October 30, 2006.

A. Summary of the Notice of Proposed Rulemaking (NPRM)

On October 22, 2007, the FAA published an NPRM (72 FR 59600) to revise the QPS appendices. The primary purpose of the NPRM was to ensure that the flight training and testing environment is accurate and realistic and to provide greater harmonization with the international standards documents for simulation issued by the Joint Aviation Authority (JAA) (JAR-STD 1A, Aeroplanes, and JAR-STD 1H, Helicopters), and the International Civil Aviation Organization (ICAO) (Doc 9625-AN/938, as amended, Manual of Criteria for the Qualification of Flight Simulators). The proposed requirements were expected to reduce expenses and workload for simulator sponsors by eliminating conflicts between the U.S. standards and the standards of other civil aviation authorities. The proposed amendments incorporated technological advances in simulation and standardized the initial and continuing qualification requirements for FSTDs to harmonize with the international standards documents. The comment period for the NPRM closed December 21, 2007.

B. Summary of the Final Rule

This final rule:

  • Provides a listing of the tasks for which a simulator may be qualified.
  • Requires, during aircraft certification testing, the collection of objective test data for specific FSTD functions, including: Idle and emergency descents and pitch trim rates for use in airplane simulators; engine inoperative rejected takeoffs for use in helicopter simulators; and takeoffs, hover, vertical climbs, and normal landings for use in helicopter FTDs.
  • Provides in the QPS appendices additional information for sponsors on the testing requirements for FSTDs, including the use of alternative data sources when complete flight test data are not available or less technically complex levels of simulation are being developed.
  • Clarifies and standardizes existing requirements for motion, visual, and sound systems, including subjective buffeting motions, visual scene content, and sound replication.
  • Requires, by FSTD Directive 1, all existing FSTD airport models used for training, testing, or checking under this chapter that are beyond the number of airport models required for qualification to meet the requirements described in Table A3C (Appendix A, Attachment 3) or Table C3C (Appendix C, Attachment 3), as appropriate.

Except for FSTD Directive 1, manufacturers and sponsors are not required to incorporate any of the changes listed above for existing FSTDs. The appendices and attachments to part 60 affected by this final rule only apply to FSTDs that come into service after part 60 is effective (May 30, 2008). This final rule results in minimal to no cost increases for manufacturers and sponsors.

C. Summary of Comments

The FAA received 18 comments on the proposed rule. Commenters include airlines (Northwest, American, United, and FedEx), industry organizations (Air Transport Association (ATA) and Helicopter Association International (HAI)), training organizations (Alteon), manufacturers (Boeing, Thales, CAE, and Rockwell Collins), and individuals. Start Printed Page 26479

All of the commenters generally supported the proposal, but the majority of commenters had specific suggestions to revise the proposed rule. Most of these suggested revisions were technical edits. None of the comments resulted in any substantive changes to the proposed requirements, and we have incorporated the suggestions where appropriate. We have also made minor editorial revisions where appropriate.

The FAA received comments on the following general topics:

  • Administrative.
  • Simulator Qualification and Evaluation.
  • FSTD Testing: Objective and Subjective.
  • General.
  • Visual Systems.
  • Motion or Vibration Requirements.
  • Sound Requirements.
  • Helicopters.
  • Quality Management System (QMS).
  • Miscellaneous.

II. Discussion of the Final Rule and Comments

A. Administrative

The ATA recommended that the FAA make the effective date of the final rule at least 90 days following the publication date.

Part 60 has been available to the public for review for over 1 year. The revisions to the appendices of Part 60 reflect international standards that have been in existence for more than 4 years. Further, when the FAA delayed the effective date to Part 60, we also delayed the compliance dates of certain sections of the rule to provide adequate time for transition. Because of the notice provided and delayed compliance dates of certain sections, the FAA has determined that delaying the effective date by 90 days is not necessary.

Several of the comments were beyond the scope of the proposal. For example, CAE and others suggested including objective tests for Heads-Up Displays (HUD) and Enhanced Visual Systems (EVS). Further, several commenters suggested adopting standards currently being developed by the International Working Group (IWG) of the Royal Aeronautical Society (RAeS).

The FAA has not addressed in detail the comments that are beyond the scope of the NPRM. In addition, the FAA has determined it would be premature for the FAA to incorporate into this final rule the standards currently under review by the IWG. Once the RAeS has adopted the IWG's recommendations, the FAA will review them for incorporation in the QPS appendices.

Several commenters noted differences between the proposed standards and the current international standards and suggested adopting the international standards. As stated, one of the purposes of this rule is to harmonize with the current international standards documents for simulation issued by the JAA and ICAO. These recommendations are within the scope of the proposal and have been incorporated into this final rule as appropriate.

Some commenters to the proposed rule noted typographical and formatting errors in the proposal. The Office of the Federal Register issued a correction document addressing some of the these errors on March 5, 2008 (73 FR 11995). The FAA has addressed the remaining errors in this document.

B. Simulator Qualification and Evaluation

CAE and others noted that the listing of tasks for which an FSTD may be qualified do not correspond to the tasks set forth in the FAA Air Carrier Operations Inspector's Handbook and are not the same as those tasks in the tables that outline the Functions and Subjective tests for which each FSTD may be evaluated. Commenters also suggested that the objective and subjective tests used to evaluate the FSTD be aligned with the tasks for which the FSTD may be qualified.

The FAA recognizes that the FSTD qualification tasks do not mirror the tasks set forth in the FAA Air Carrier Operations Inspector's Handbook, the “Functions and Subjective tests” tables in Attachment 3 of Appendices A-D, and the “Tasks vs. Simulator Level” tables in Attachment 1 of Appendices A-D. However, there are differences between the tasks used to evaluate the handling, performance, and other characteristics of the FSTD and those tasks for which an FSTD may be qualified for pilot training, testing, or checking activities. Thus, the list of tasks set forth in the “Functions and Subjective tests” tables and “Tasks vs. Simulator Level” tables are not necessarily the same, nor should they be the same.

CAE, ATA, Rockwell Collins, and others asked whether the Level B simulator authorizations in Table A1B should be listed as an “X” instead of an “R” for most of the landing tasks.

As the legend in Table A1B indicates, the “R” denotes authorization for Recurrent activities while the “X” denotes authorization for Initial, Transition, Upgrade, and Recurrent activities. The landing tasks for Level B simulators are restricted to Recurrent activities and the “R” in the table at those points is the correct reference. However, the FAA acknowledges that the authorizations for Taxiing and for Normal and Crosswind Takeoffs for the Level B simulator were inadvertently left blank, and the FAA has placed an “R” in those positions in this table, indicating an authorization for Recurrent activities in this level of simulation.

American, the ATA, and others stated that the differences between “update” and “upgrade,” as used in Appendix A, Paragraph 13, Previously Qualified FFS, subparagraph “h,” were not clear. They recommended clarifying the differences and moving the subparagraph from the information section to the QPS Requirements section.

The information in subparagraph “h” allows for Full Flight Simulators (FFS) to be updated without requiring an evaluation under the new standards. Because this language is permissive in nature, we have moved it to the QPS Requirements section as requested. To clarify the meaning of these terms, we have added a definition of “update” that reflects current practice to Appendix F.

CAE and others suggested revising the note in Table A1B, entry 3.f, Recovery from Unusual Attitudes, by replacing the statement “supported by applicable simulation validation data” with “supported by the simulation models.”

The suggested revised language would allow an individual to go beyond the flight-test-validated flight-envelope in a flight simulator. This is not an acceptable practice because of the lack of information about aircraft performance and handling beyond those limits. Therefore, the FAA has not adopted the recommendation.

The ATA, Northwest, and others suggested clarifying that the 24-hour “look back” period for the functional preflight check (Table E1, entry E1.20) is from the beginning of the scheduled training period. Additionally, commenters questioned whether the FSTD use-period, if started within 24 hours of a functional preflight check, could continue beyond that 24-hour “look-back” period and whether the functional preflight check is required for Level 4 “touch screen” FTDs. Further, commenters questioned whether Level 4 FTDs remain under the responsibility of the Training Program Approval Authority (TPAA).

The proposed requirement for conducting a functional preflight check within 24 hours prior to using the FSTD is to ensure that technical personnel with the requisite preflight training have determined the readiness level of the FSTD. An FSTD use-period does not begin unless a functional preflight check Start Printed Page 26480has been completed in the previous 24 hours. If a training session begins near the end of the 24 hours after the functional preflight check was completed, the training session may continue beyond that 24 hours. However, any subsequent training session may not begin until another functional preflight check is conducted.

The National Simulator Program Manager (NSPM) is the FAA manager responsible for the evaluation and qualification of all FSTDs qualified under part 60, including Level 4 FTDs. The NSPM will continue to exercise this responsibility through inspectors and engineers assigned to the National Simulator Program (NSP) staff and others to whom the NSPM may delegate that responsibility and authority. This responsibility and authority is not intended to undermine or compromise the duties and responsibilities of the assigned TPAA with regard to the approved use of the FSTD.

CAE and others questioned when it would be necessary to complete an additional initial qualification evaluation after a modification to the FSTD. They also asked what principles would be used in determining whether an evaluation for additional authorization(s) is necessary and if an evaluation is necessary, when it must take place.

Whether a modification necessitates an additional initial qualification evaluation, necessitates part of an initial qualification evaluation, or does not necessitate an additional evaluation, depends on (1) the extent of the modification; (2) whether the modification impacts, or is impacted by, other systems or equipment in the FSTD; and (3) whether, as a result of the modification, the FSTD operation is consistent with the airplane system it is simulating. After review of these factors, the FAA will determine on a case-by-case basis whether an evaluation for additional authorizations is required and when it will take place.

The ATA, Northwest, and others suggested that the windshear provisions in Table A1A for each Level C and Level D FFS not be required for evaluation and qualification purposes because not all aircraft are required to have windshear equipment and not all pilots are required to train on recovery from inadvertent windshear encounters. Further, the commenters also suggested clarifying the aircraft conditions under which the windshear demonstrations must be conducted.

Only operations conducted in accordance with 14 CFR part 121 that use aircraft listed in § 121.358 require windshear training for crewmembers. Accordingly, the FAA has modified Table A1A to address only these operations. We have also clarified the aircraft conditions under which the windshear demonstrations must be conducted.

C. FSTD Testing: Objective and Subjective

1. General

The ATA, Rockwell Collins, and others recommended requiring Level A and Level B simulators to meet the standards in Table A2A, entry 1.b.7, Dynamic Engine Failure After Takeoff.

The standards for testing of dynamic engine failures after takeoff were first established by ICAO and were limited to advanced simulators, now referred to as Level C and Level D. One purpose of this final rule is to harmonize FAA standards with current international standards. Because current international standards do not set forth standards for testing dynamic engine failure after takeoff for level A and B simulators, the FAA has not adopted the recommendation.

The ATA, Northwest, Boeing, CAE, and others suggested the FAA review all the references in Appendix A, Attachment 2, Table A2A, Table of Objective Tests, that include references to Computer Controlled Aircraft (CCA) to ensure that the control state testing requirements (i.e., normal control state or non-normal control state) are correctly addressed.

The FAA recognizes that there were errors made in the proposal regarding CCA testing requirements. The FAA has reviewed the CCA testing requirements to address the correct control state and made appropriate revisions.

CAE, Rockwell Collins, ATA, and others submitted several comments on Appendix A, Attachment 1, Table A1A, General Simulator Requirements. CAE suggested that (1) the manual and automatic testing, described in entry 2.f, and simulator control feel dynamics, as described in entry 3.e, apply to Level A and Level B simulators in addition to Level C and Level D simulators; (2) the NSPM should further clarify the number of malfunctions that are required or provide a list of the necessary malfunctions that should be present; and (3) the instructor controls, as described in entry 4.c, either list all the expected environmental conditions over which the instructor should have control or remove the reference to “wind speed and direction.” The ATA and others requested that the statements about additional field-of-view capability for Level A and Level B simulators in entry 6.b of Table A1A be moved to the Information/Notes column.

Automatic testing and control feel dynamics was first required in 1980 with the publication of the FAA's Advanced Simulation Plan and was limited to advanced simulators, now referred to as Level C and Level D. The FAA is not expanding the requirements for automatic testing and control feel dynamics testing to Level A and Level B simulators because that would result in differing technical requirements for these simulator levels while authorizing the same training, testing, and checking tasks. The additional field-of-view reference in entry 6.b was designed to allow the option of including a larger field-of-view than the provision requires, with the understanding that the minimum fields of view would have to be retained. This reference is more informative than regulatory and the FAA has moved the statements to the Information/Notes column.

The ATA and others suggested defining the term “least augmented state” as used in Appendix A, Attachment 2, paragraph 2.j, and requested confirmation that the “least augmented state” is one that the pilot may select using normal switches found in the airplane flight deck.

The FAA has determined that a general definition of the term “least augmented state” is not appropriate because these states are dependent on the aircraft type involved. Additionally, the least augmented state is not necessarily achieved by the use of switches found in the flight deck. Therefore, the FAA will evaluate FSTDs in accordance with the least augmented state data supplied by the aircraft manufacturer or other data supplier.

The ATA, Rockwell Collins, and others suggested that the primary controls of the simulated aircraft should be tested objectively to verify correct forces and responses whether simulated aircraft parts or actual aircraft parts are used. Further, they recommended that the FAA require a Statement of Compliance and Capability (SOC) that describes how and where the control forces are generated in the aircraft, and lists all hardware required to generate these control forces.

The FAA does not require testing of flight controls in these circumstances because these aircraft controls must be maintained as if they were installed in an aircraft to provide crewmembers the same control feedback as felt in the actual aircraft. The sponsor is required to provide a statement that the aircraft hardware meets the appropriate manufacturer's specifications for the controls and the sponsor must have Start Printed Page 26481information supporting that statement available for NSPM review. Accordingly, the FAA has not adopted the recommendation.

Boeing suggested, with regard to Table A2A, entry 1.c.2, that the test for “One Engine Inoperative” should be named “One Engine Inoperative, Second Segment Climb.”

The test is required for airplanes certificated under both parts 23 and 25. The term “Second Segment Climb” applies only to airplanes certificated under part 25. Therefore, the FAA has not adopted the suggested change.

The ATA, Rockwell Collins, CAE, and others recommended that the tests in entries 1.e.1 and 1.e.2, Stopping Time and Distance, of Table A2A, not apply to Level A and Level B simulators because these simulator levels are not authorized to perform this landing task.

The FAA did not adopt this change because both Level A and Level B simulators are authorized to perform Rejected Takeoff Maneuvers. In addition, Level B simulators are authorized to perform landings in recurrent training and checking. Therefore, these tests are necessary to determine the stopping capabilities of the FSTD.

The ATA, Boeing, CAE, and others expressed concern over how to read the test requirements for Engine Acceleration and Engine Deceleration (Table A2A, entries 1.f.1 and 1.f.2). The commenters recommended various ways of publishing the established tolerances. CAE also recommended defining the terms “Ti” and “Tt.”

The published tolerances for these tests are consistent with international standards documents. As proposed, Ti and Tt were defined in the Tables as well as in the Abbreviations list in Appendix F. For clarification, we have moved these terms to the definitions section of Appendix F and added cross references in the tables to Appendix F.

The ATA, Northwest, and others noted that the Short Period Dynamics test in Table A2A, entry 2.c.10 erroneously did not to apply to Level A simulators. They also noted that entry 2.d.7, Dutch Roll (yaw damper off), erroneously applied to all levels of simulators when it should apply only to Levels B, C, and D.

The FAA acknowledges that applicability to Level A simulators for the Short Period test was inadvertently omitted and the Dutch Roll test was inadvertently included, although the correct standards appear in FAA standards documents and international standards documents. The FAA has corrected these errors in this final rule.

CAE suggested the FAA clarify Table A2A, entry 2.d.8, Steady State Sideslip, by stating that this test ``may be a series of snapshot test results using at least two rudder positions, one of which should be near maximum allowable rudder.''

The FAA agrees and has clarified the requirement where appropriate. CAE and others suggested that the definition of the term ``snapshot'' be modified from ``a presentation of one or more variables at a given instant of time'' to ``a presentation of one or more variables at a given instant of time or from a time-average of a steady flight condition.''

The FAA has determined that the suggested modification would create confusion because of the subjective nature of the phrase ``steady flight condition'' and has not adopted the suggestion.

The ATA and others suggested a change to Table A2A, entry 2.e.6, All Engines Operating, Autopilot, Go-Around, to require a manual test and, if applicable, an autopilot test.

The FAA currently requires a manual test when performing a one engine inoperative go-around. The all engines operating, autopilot, go-around test applies only when the airplane is authorized to use the autopilot function during a go-around. Because both tests are currently required, the FAA has not adopted the suggested changes.

The ATA, Rockwell Collins, and others suggested that the tests described in entries 2.e.8 and 2.e.9 of Table A2A, should be conducted differently (i.e., with the nosewheel steering disconnected or castering), unless the FAA's intent was to evaluate overall aircraft response, in which case no change is necessary.

The intent of these tests is to evaluate the aircraft response. Therefore, no change is necessary.

CAE and Boeing recommended substituting the term ``mass properties'' with the term ``fuel slosh'' in Appendices A and C, paragraph 8.h(2)(c) because mass properties are rarely, if ever, run in an integrated manner as described.

The FAA does not agree that mass properties are not run in an integrated manner. The FAA has chosen the term mass properties because it is consistent with international standards. Therefore, the FAA has not adopted the suggested change.

CAE and Boeing recommended deleting paragraph 9.b(3) in Appendices A and C because a data provider should not have to demonstrate that data gathered from an engineering simulation (in lieu of a flight test source) has necessary qualities to qualify an FSTD.

The FAA did not intend that an engineering simulation be qualified, or be capable of being qualified, as an FSTD. The data obtained from the engineering simulation would be appropriate as a replacement for flight test data when the data obtained from the engineering simulation is programmed into an FSTD. Therefore, we have clarified the information in paragraph 9.b(3) to state that in these cases, the data provider should submit validation data from an audited engineering simulator/simulation to supplement specific segments of the flight test data.

CAE and Boeing requested that paragraph 11.a(1) not apply to Table A2A, entries 1.f.1 and 1.f.2, objective tests for engine acceleration and deceleration. Rather, they suggested applying 100% of flight test tolerances to these objective tests. CAE also suggested when flight test data for an alternate engine fit is unavailable, the objective testing of engine acceleration and engine deceleration (Table A2A, tests 1.f.1 and 1.f.2) should be exempt from the 20% tolerance for the application of engineering simulator/simulation because the actual tolerance would be less than the simulation iteration rate.

Applying 100% of flight test tolerances to the objective tests results in these entries is not an acceptable routine procedure. Full flight test tolerances are appropriate when comparing FSTD results to airplane data, and 20% of those airplane tolerances are appropriate when comparing FSTD results to flight engineering simulation data because it is easier to match ``computer to computer'' data than to match ``computer to airplane'' data. Any circumstance that does not fit within these parameters would likely be acceptable under the ``best fit'' data selection set forth in Appendix A, Attachment 2, paragraph 2.d. Therefore, the FAA has not adopted these changes.

The ATA and others stated that the Rudder Response test in Table B2A, entry 2.b.6.b is confusing because it would not test the rudder power in the yaw axis. They suggested modifying the tolerance column to read ``± 2°/sec or ± 10% yaw rate, OR Roll rate ± 2°/sec, bank angle ± 3°.''

This test was originally required as a rudder test using roll rate and bank angle for the parameters. However, the FAA agrees that this test may be accomplished using either yaw rate or roll rate and bank angle. Therefore, the FAA has added a note in the Information/Notes column that this test Start Printed Page 26482may be accomplished as a yaw response test.

The ATA, Northwest, CAE, and others suggested eliminating the ±2 degree tolerance on bank angle above stick shaker or initial buffet speeds in Table A2A, entry 2.c.8, Stall Characteristics, to be consistent with international standards.

The FAA acknowledges that the ± 2 degree tolerance on bank angle above stick shaker or initial buffet speeds is not included in the international standards. However, requiring zero tolerance in these instances would be very stringent without appreciable difference in FSTD performance or handling characteristics. Accordingly, the FAA has not eliminated the tolerance.

Boeing, United, and others recommended clarifying paragraph 11.b(5) Validation Test Tolerances, and adding a new paragraph 11.b(6) allowing errors greater than 20% if the simulator sponsor provides an adequate explanation.

The FAA generally agrees with the suggestion and has modified paragraph 11.b(5) to reflect this information. The FAA has determined that adding a new paragraph 11.b(6) is not necessary.

One commenter, citing paragraph 17.a, ``Alternative Data Sources, Procedures, and Instrumentation: Level A and Level B Simulators Only,'' questioned whether the alternative data collection sources, procedures, and instrumentation listed in Table A2E were the only sources for data collection that the FAA would allow.

Appendix A, paragraph 11, Initial (and Upgrade) Qualification Requirements, requires objective data to be acquired through traditional aircraft flight testing. It also allows for the use of ``another approved'' source. The FAA has included Table A2E to provide alternative sources, procedures, or instrumentation acceptable to the FAA that may be used to acquire the necessary objective data for Level A or Level B simulators. At this time, the alternative data collection sources, procedures, and instrumentation listed in Table A2E are the only alternatives acceptable without prior approval by the NSPM.

The ATA, Rockwell Collins, and others questioned the necessity of having sounds of precipitation and rain removal devices for Level C simulators but not requiring the corresponding visual effect.

The FAA recognizes the error in the proposed language and has made the necessary changes. Level C simulators are required to be subjectively tested for the sound, motion and visual effects of light, medium and heavy precipitation near a thunderstorm and the effect of rain removal devices.

The ATA and others requested that aircraft certified with auto-ice detection coupled with auto-anti-ice or auto-de-ice capabilities be exempt from the effects of airframe and engine icing tests listed in Table A3F, Special Effects.

Because it is possible for flight crews to experience the effects of airframe or engine icing if the auto-ice detection systems are inoperative, the flight crews must be trained to recognize and respond to icing situations. Therefore, the FAA has not adopted the recommendation.

2. Visual Systems

The ATA, Northwest, Rockwell Collins, United, and several others recognized that the definition of an FSTD Directive is ``a document issued by the FAA to an FSTD sponsor requiring a modification to the FSTD due to a safety-of-flight issue and amending the qualification basis for the FSTD.'' These commenters asserted that the FAA has not provided any safety analysis to support the issuance of FSTD Directive 1. Further, these commenters asked how the FAA determines what constitutes a safety issue that would warrant the issuance of an FSTD Directive. Some commenters asserted that updating airport modeling is a complicated problem because of the difficulty in removing airport models from the instructor operating station (IOS) in some FSTDs, particularly in those FSTDs not owned or controlled by the sponsor. In addition, some commenters noted the cost of updating an existing airport model and suggested that the FAA continue to allow custom airport models meeting individual training requirements to be used without modification. Further, the commenters requested the FAA extend the timeframe for updating airport models to match any modification to the actual airport.

As proposed, FSTD Directive 1 requires each certificate holder to ensure that each airport model used for training, testing or checking, except those airport models used to qualify the simulator at the designated level, meets the requirements of a Class II or Class III airport model. The FAA acknowledges that FSTD Directives may be issued only for safety-of-flight purposes. These determinations will be made on a case-by-case basis. The FAA has determined that updating airport modeling is a safety-of-flight concern because pilots have landed airplanes on wrong runways, landed on taxiways, landed at the wrong airport, unknowingly taxied across active runways, and taken off from the wrong runway. Many FSTD users have expressed concern regarding the accuracy of these models with respect to real world airports. Training, testing, or checking in an FSTD with incomplete or inaccurate airport models representing real world airports can contribute to incomplete planning or poor decision making by pilots if they subsequently operate into or out of that real world airport. While these potentially disastrous occurrences happen infrequently, inaccurate airport modeling is a safety-of-flight issue that warrants the issuance of this FSTD Directive.

The proposed FSTD Directive is designed to address qualified FSTDs that contain airport models that were not evaluated. The FSTD Directive ensures that each model used in an FSTD for training, testing, or checking activities meets the acceptable minimum standards. Although the FAA is responsible for ensuring that these standards are met, the FSTD sponsor is responsible for maintaining the FSTD, and each certificate holder using the FSTD is responsible for ensuring that all of the FSTD components are in compliance with these standards and report any deficiencies.

Upon review of the comments, however, we have clarified the language of the FSTD Directive. The FSTD Directive still requires each certificate holder to ensure that, by May 30, 2009, except for the airport model(s) used to qualify the FSTD at the designated level, each airport model used by the certificate holder's instructors or evaluators for training, testing, or checking under 14 CFR chapter I in an FFS, meets the definition of a Class II, or Class III airport model as defined in part 60, Appendix F. We originally proposed to require removal of all airport models that did not meet the standards of a Class II or Class III model. In light of comments regarding the expense of such removal and issues regarding the sponsorship and leasing of FSTDs, FSTD Directive 1 now requires only the airport models used for training, testing or checking to meet the appropriate requirements; it does not require removal of other airport models. Additionally, we have revised the definition of a generic airport model in Appendix F to clearly describe a Class III airport model that combines correct navigation aids for a real world airport with an airport model that does not depict that real world airport. Use of such an airport model may require some limitations on that use. The clarified language in the FSTD Directive and the Start Printed Page 26483revised definitions may mitigate the actual cost of updating airport models. In addition, the FAA recognizes that it takes time to design, construct, and implement changes to computer programming. The FAA has decided to modify the time requirements in paragraph 1(f) of Attachment 3, Appendix A, and clarify the process for requesting an extension for the update in paragraph 1(g) of Attachment 3, Appendix A.

Further, the ATA and others suggested adding a statement in the Information/Notes column of Table B1A regarding visual systems that FSTD Directive 1 does not apply to Level A standards for an FTD visual system.

If a visual system installed in any level of FTD is not being used to acquire additional training credits, FSTD Directive 1 does not apply. However, if the visual system is being used to acquire training credits, the visual system must meet the requirements of at least a Level A FFS visual system. In these circumstances, FSTD Directive 1 could affect the airport models used in that system. Therefore, the FAA has not added the suggested statement.

The ATA, Rockwell Collins, and others noted that the terms visual scenes, visual models, and airport models, appear to be used interchangeably in the NPRM.

The FAA has adopted the term “airport model” instead of the terms “visual scene”or “visual model”throughout this final rule. We also have deleted the definition of “visual model” from Appendix F and changed the definition of “visual database” to “a display that may include one or more airport models” for consistency. Since there are three classes of airport models, we clarified the differences between Class I, Class II, and Class III in the definition of airport model.

ATA, Rockwell Collins, and others questioned the need for 16 moving models as well as the training tasks that would be able to be met by having these moving models. The commenters also requested clarification regarding what constitutes gate clutter.

The primary goal of the NPRM was to harmonize with international standards. The intent of the 16 moving objects requirement, which is an international standard, is to enhance the “realism”of the displayed visual scene. The FAA has added a definition of gate clutter in Appendix F, as described in entry 2.f in Table A3B.

The ATA, Rockwell Collins, and others stated that the Class II airport model requirements are excessive, especially for areas other than the “in-use” runway itself and noted that there are no model content requirements for “generic airport models.”

The Class II airport model requirements mirror the long-standing guidance in AC 120-40B, Airplane Simulator Qualification, Appendix 3, and are consistent with international standards. The FAA has determined that providing specific model content requirements for “generic airport models” would restrict unnecessarily the capability and flexibility that currently exists. Accordingly, the FAA has not made any changes to the Class II airport model requirements or created any specific requirements for “generic airport models.”

The ATA, Rockwell Collins, CAE, and others questioned whether “ambient lighting” in Daylight Visual Scenes is required.

Ambient lighting is not required in daylight visual scenes because of its distorting effects on the visual scene and inside the flight deck. The FAA has removed the requirement for ambient flight deck lighting where appropriate.

The ATA and others requested that the FAA clarify the Surface Movement Guidance and Control System (SMGCS) as referenced in Table A3B, entry 2.j.

Entry 2.j requires that a low visibility taxi route must be demonstrated for qualification of a Level D simulator. A low visibility taxi route could be satisfied, according to the Table A3B, by a depiction of one of the following means: an SMGCS taxi route, a follow-me truck, or low visibility daylight taxi lights. For further information on SMGCS, see AC 120-57A (December 19, 1996).

The ATA, Rockwell Collins, and others questioned the language in the preamble of the NPRM describing the visual system proposal as requiring a “field of view and system capacity requirements” * * * increased by 20 percent over the present requirement.” The commenters asserted that the proposed surfaces and light point requirements are “considerably in excess of a 20% increase.”

The 20% increase, as described in the NPRM preamble, should have applied only to the field-of-view requirements. However, the actual requirements stated in the proposed rule language for field-of-view and system capacity for generating surface and light points are consistent with current international standards. Further, the metrics simulator manufacturers are currently using to construct their equipment correspond to the proposed system capacity for generating surface and light points. Therefore, no changes to the rule language are necessary.

The ATA, Rockwell Collins, and others objected to the larger field-of-view requirements for FSTDs previously built but not evaluated by the FAA for qualification, and for FSTDs previously evaluated and qualified, but returning to service after a 2-year inactive interval. The concern is that these FSTDs would be required to meet the new field-of-view requirements.

The first time an FSTD is evaluated by the FAA for qualification, the FSTD is evaluated in accordance with the set of standards current at that time. An FSTD placed into an inactive status for 2 or more years will not necessarily be evaluated under any new criteria in effect at the time of re-entry into service. The NSPM, however, considers a full range of factors before deciding whether to require an FSTD coming out of an inactive period to be evaluated in accordance with its original qualification basis or in accordance with the set of standards current at that time.

CAE and others recommended modifying in Table A1A, entry 6.p, to require the visual system be free from apparent and distracting quantization, instead of only apparent quantization.

Eliminating the slightest traces of quantization cannot be technically accomplished. However, because distracting quantization can be minimized to such a level that it does not affect the performance of the visual system, the FAA has made this change.

CAE, ATA, Rockwell Collins, and others questioned why realistic color and directionality of all airport lighting is not a requirement for Level A, Level B, and Level C simulators in addition to Level D simulators.

As proposed, the airport lighting requirements for Level A and B simulators are consistent with international standards. Therefore, the FAA has not made the requested change.

The ATA, Northwest, and others suggested including a test in Table A2A, entry 4.b.3, for Level C simulators to evaluate visual systems with 150° horizontal and 30° vertical field-of-view or a monitor-based system.

The primary goal of the NPRM was to harmonize with international standards. The current international standard, as reflected in the NPRM, for Level C simulators is 180° horizontal by 40° vertical field-of-view. Therefore, the FAA has not adopted the change.

The ATA, Rockwell Collins, and others stated that the test in Table A2A, entry 4.f, Surface Resolution, does not reflect current practice for runway markings. Commenters recommended that this test mirror the current practice Start Printed Page 26484and international standards that runway stripes and spaces be 5.75 feet wide.

The FAA has modified this language where appropriate to reflect current practice and international standards.

The ATA, Rockwell Collins, CAE, and others questioned why the tolerances allowed in entry 4.i, Visual Ground Segment (VGS), of Table A2A are different from the current international standards. They also suggested that the Qualification Test Guide (QTG) contain calculations to compare the altitude used against the altitude specified when performing this test and questioned whether the test must be performed manually. They also requested deleting or correcting the conversion of feet to meters.

The international standards prescribe the application of the VGS tolerance to the far end of the VGS with no tolerance provided at the near end of the VGS. To ensure harmonization, the FAA has made the appropriate changes to the application of this VGS tolerance. The requirements for the QTG contain provisions regarding the calculation of altitude references. The FAA has stated that the altitude calculations are computed with the aircraft at 100 ft (30 m) above the runway touchdown zone and centered on the Instrument Landing System (ILS) electronic glide slope. The typical reference for modern turbojet aircraft operations for height above touchdown is the height of the main landing gear above that touchdown zone reference plane, with the aircraft at a specified weight and landing configuration. To clarify these calculations, the FAA has modified the Flight Conditions column for entry 4.i of Table A2A to reflect this information. The distances expressed in metric units are not direct conversions to U.S. customary units, nor were they intended to be. Rather, these are the appropriate standards depending on which system is being used. Therefore, the FAA has not removed the metric references.

The ATA and others requested clarification regarding the term “in-use runway” in Tables A3B and A3C. The commenters stated that using the general term “in-use runway” would require modeling all taxiways rather than the primary one used, which may overload the visual system and negatively impact training.

Each “in-use” runway is a single, one-direction runway, used for takeoffs and landings, that has the required surface lighting and markings. New visual systems are capable of generating substantially more detail than required by this final rule. However, because of the concern raised regarding associated taxiways, the FAA has modified the language in Appendices A, C, and D regarding airport model content to require the use of only the primary taxi route from parking to the end of the runway instead of requiring the modeling of all potential taxi routes.

One commenter requested the FAA provide a definition of the term “dynamic response programming,” to clarify the requirements in Table A1A, entry 6.h. CAE and others questioned the use of the terms “correlate with integrated airplane systems, where fitted,” and “dynamic response programming,” as they are used in Tables A3B and A1A. Commenters also noted that Table A3B, entry 6.d erroneously applied the requirements for “correlate with integrated airplane systems” to all levels of simulators rather than just Levels C and D.

The term “dynamic response” is used in its typical engineering context. As used in Tables A1A (entry 6.h) and C1A (entry 6.i) “dynamic response programming” requires the visual system display to respond with the continuous movement of the simulated aircraft. We have clarified the language in Tables A3b (entry 6.d), C3b (entry 6.d) and D3B (entry 5.d) by removing the phrase “where fitted.” The requirement that the visual scene correlate with the integrated aircraft systems is to ensure that all installed integrated aircraft systems correctly respond to what appears in the visual scene. This visual correspondence requirement applies to only Level C and D simulators and the FAA has corrected this error in Tables A3B and C3B.

The ATA, Rockwell Collins, and others suggested there should be no difference between entries 6.e and 8.g in Table A3B.

These two entries are designed to test separate conditions. Entry 6.e tests the external lights to ensure correlation with the airplane and associated equipment while entry 8.g tests the environmental effects of the external lights in the visual system. Because of the separate, distinct purposes of these entries, they should not be the same, and the FAA has not adopted the recommendation.

The ATA, Rockwell Collins, and others objected to the inclusion of several visual, sound, or motion systems features (e.g., the effect of rain removal devices; sound of light, medium, and heavy precipitation; and nosewheel scuffing) in the airport model presentations because they are not airport model functions.

These features are a function of the visual, sound, or motion systems. These features must be available and operate correctly in conjunction with the airport models presented during training, testing, or checking activities. These features are meaningful only when they are presented as part of the airport model. Therefore, the FAA has not removed these features from the airport model requirements.

The ATA, Northwest, Rockwell Collins, and others expressed concern that the discussion of entry 10 in Table A3B regarding the combination of two airport models to achieve two “in-use” runways at one airport, may impede control of the radio aids and terrain elevation and create distracting effects in the visual scene display.

The discussion in entry 10 of Table A3B is an authorization, not a requirement. If an FSTD has limitations such that this combination would impede control or create distracting effects, this particular authorization is not applicable. The FAA has added clarifying language in entry 10 to address this concern.

The ATA, Rockwell Collins, and others stated the requirement that “slopes in runways, taxiways, and ramp areas must not cause distracting or unrealistic effects” in entry 4.b in Table A3C implies that Level A and Level B simulators are required to have sloping terrain modeling, making the Class II airport models more stringent than Class I airport models.

Level A and B simulators are not required to have sloping terrain modeling. This provision, however, sets forth the requirements for such modeling if a sponsor elects to incorporate sloping terrain modeling in the FSTD. The FAA has clarified this requirement by adding the qualifier “if depicted in the visual scene,” in the appropriate tables in Appendices A, C, and D.

CAE and others requested the FAA establish a list of individuals or corporations who work as visual modelers and can provide detailed information about airports without creating national security concerns.

Anyone with a legitimate need for the acquisition of detailed airport information for accurate modeling of any U.S. airport for simulation modeling purposes should contact the NSPM for assistance.

3. Motion or Vibration Requirements

Rockwell Collins, CAE, the ATA, and others stated that Motion Cueing Performance Signature tests can provide an objective means of determining loss in motion system performance. The commenters were concerned that if these tests were conducted only during the Initial Qualification Evaluation, sponsors would not have objective Start Printed Page 26485information available to determine the continuing status of the motion system.

The proposal required the results of these tests to be included in the MQTG. Because sponsors are required to run the complete quarterly MQTG inspections, these tests are not intended to be one-time-only tests. The sponsor and NSPM regularly review these tests. The FAA agrees that the statement “this test is not required as part of continuing qualification evaluations” is misleading and has deleted this statement where appropriate.

The ATA, Rockwell Collins, and others questioned whether Level B simulators must be subjectively tested for nosewheel scuffing motion effects when this level of simulator was not authorized for the taxi task.

Level B simulators are authorized for Rejected Takeoff Maneuvers. At higher speeds, the movement of the nosewheel steering mechanism can be more sensitive and may cause the nosewheel to be turned beyond smooth tracking angles, resulting in nosewheel scuffing during Rejected Takeoff Maneuvers. Therefore, the FAA has determined that subjective testing for nosewheel scuffing motion effects is necessary and did not make any change.

4. Sound Requirements

The ATA, Rockwell Collins, and others suggested that in Table A2A, entry 5, Sound Requirements, the tests listed should have a defined frequency spectrum within which the tests should be conducted similar to that set forth in international standards.

Because the text in the proposal describes these processes and similar statements appear in international standards, the FAA has added language similar to the international standards to the sound test requirements of entry 5, Table A2A.

The ATA, Rockwell Collins, and others suggested requiring all levels of FTDs to be able to represent all the flight deck aural warning sounds and sounds from pilot actions instead of limiting this standard to level 6 FTDs, as it currently appears in entry 7.a of Table B1A.

A Level 6 FTD is the only level of FTD that is required to have all aircraft systems installed and operational. This requirement has been in effect for over 16 years and is consistent with current international standards. The suggested requirement is also outside the scope of this rulemaking. Accordingly, the FAA has not adopted the change.

CAE and others suggested entry 7.c, Accurate Simulation of Sounds, in Table A1A, address abnormal operations in addition to the sound of normal operations and the sound of a crash.

The current international standards contain a requirement for sounds addressing abnormal operations, which include the sound of a crash, and normal operations. To harmonize with international standards the FAA has made the change.

D. Helicopters

CAE and others noted that an SOC is not necessary for entries 1.a, 1.b, and 2.a in Table C1A. Thales also suggested that the language in entry 2.a be modified to reflect helicopter operations.

The FAA has removed the SOC requirement in entries 1.a and 1.b because it is not necessary. The SOC for entry 2.a is necessary because it describes a flight dynamics model that must account for combinations of drag and thrust normally encountered in flight. However, the FAA has modified the language in entry 2.a to better reflect helicopter operations.

Thales and others stated that the motion onset requirements in Table C1A, entry 2.e, are new requirements for helicopter simulation.

The FAA included the requirements in this entry in the October 30, 2006, final rule (71 FR 63426), and again in the NPRM for this rule. These requirements codify existing practice (e.g., AC 120-63, Helicopter Simulator Qualification).

CAE and others suggested that the Information/Notes column in Table C1A, entry 2.f, include “roll” as well as “pitch,” “side loading,” and “directional control characteristics,” when simulating brake and tire failure dynamics.

The FAA has clarified the Information/Notes column by adding the phrase “in the appropriate axes,” which includes roll, pitch, yaw, heave, sway (side loading), and surge.

Thales, CAE, and others suggested that the requirements in Table C1A, entry 2.g.1, regarding ground effect should apply to Level B simulators as it appears in table C1A, entry 2.c.1.

The FAA has separated these two requirements because helicopter simulator Levels B, C, and D may be required to perform running takeoffs and running landings, as described in entry 2.c.1. However, only Level C and D simulators are required to perform takeoffs or landings to or from a hover, as noted in entry 2.g, thus requiring separate table entries. Accordingly, the FAA has not adopted the recommendation.

CAE and others requested clarification regarding the kinds of aircraft system variables and environmental conditions as listed in Table C1A, entry 4, that must be used in simulation. Commenters suggested removing the reference to “wind speed,” including other environmental controls, and including “water spray” when hovering over water.

There is no specific list of system variables that must be available in a helicopter simulator. The requirement is that the instructor or evaluator be able to control all the system variables and insert all abnormal or emergency conditions into the simulated helicopter systems as described in the sponsor's FAA-approved training program, or as described in the relevant FSTD operating manual. The FAA has reviewed the entries for environmental controls and has included additional examples of environmental conditions that may be available in the FSTD. We also have included “water vapor” as an example of what may be expected to be re-circulated when hovering above the surface, as suggested by the commenters.

CAE, Thales, and others suggested including vortex ring and high-speed rotor vibrations for motion effects programming requirements in Table C1A, entry 5.e. Commenters also suggested requiring Level B and C simulators to demonstrate air turbulence models.

As proposed, entry 5.e included requirements for buffet due to settling with power and rotor vibrations. As the commenters noted, these terms are better expressed as buffet due to vortex ring, and high-speed rotor vibrations. The FAA has clarified the requirements as requested. The FAA also has clarified the statement in the Information/Notes column regarding the use of air turbulence models. Further changes regarding air turbulence modeling are beyond the scope of the NPRM.

Thales and others recommended adjusting surface resolution from the currently proposed three (3) arc-minutes to two (2) arc-minutes in Table C1A, entry 6.i.(4). Additionally, Thales recommended the FAA add “helipad” or “heliport” lighting effects specific to helicopter operations for subjective testing.

As noted by the commenter, the two (2) arc-minutes requirement is the current international standard. Therefore, the FAA has made the recommended change. However, there are specific requirements for both airport and helicopter landing area models for training, testing, and checking purposes in attachment 3, and the FAA has not included the “helipad” or “heliport” lighting effects in Table C1A. Start Printed Page 26486

CAE, Thales, and others suggested that the tolerance of ±3 knots, in Table C2A, entry 1.c, Takeoff, and entry 1.j, Landing, be applied to either airspeed or ground speed, because data collected at airspeeds below 30-40 knots are often unreliable. Thales suggested that for entries 1.c.2 and 1.c.3, the specific type of takeoff (Category A, Performance, Confined area, etc,) be recorded so proper comparisons can be made.

The FAA recognizes the difficulties in applying tolerances to airspeeds when the airspeed value itself may not be accurate and has added a general authorization for Takeoff tests and Landing tests. Also, the FAA has added a note in the Information/Notes column to address the differing types of takeoff profiles used for each of these tests.

CAE and others stated that in helicopter simulation, flight test data containing all the required parameters for a complete power-off landing is not always available. CAE recommended modifying the language in Tables C2A and D2A, entry 1.j.4, Autorotational Landing, to state that in those cases where data are not available, and other qualified flight test personnel are not available to acquire this data, the sponsor must coordinate with the NSPM to determine if it is appropriate to accept alternative testing means.

The FAA agrees that, in certain circumstances, the sponsor must coordinate with the NSPM to determine if it is appropriate to accept an alternative testing means. The FAA has made the appropriate changes.

CAE and others stated that Table C2A, entry 1.h.2, Autorotation Performance, requires data be recorded for speeds from 50 knots, ±5 knots, through at least maximum glide distance airspeed. However, the maximum allowable autorotation airspeed is often slower than the maximum glide distance airspeed, which would prevent accurate data for autorotation entry.

The FAA has modified the test details to include maximum allowable autorotation airspeed.

CAE and others suggested reducing the tolerance for control displacement to ±0.10 inches in Table C2A, entry 2.a.6, Control System Freeplay. The commenters also suggested harmonizing the tolerance requirements for FTDs in Table D2A, entry 2.a.6.

The FAA agrees and has made the appropriate changes, which reflect current international standards.

CAE and others suggested that the proposed ±10% tolerances on pitch and airspeed for non-periodic responses, in Table C2A, entry 2.c.3.a, Dynamic Stability, Long Term Response, be relaxed because the proposal is too restrictive. They noted non-periodic Augmentation-On responses generally exhibit less than 5 degrees peak pitch attitude change from trim. Further, commenters recommended adding a statement to the Information/Notes column to clarify the relationship between non-periodic responses and flight-test data. The rationale for these recommendations is to avoid requirements that are unduly restrictive with divergent results, while ensuring that the non-periodic responses are accurately reproduced.

The FAA agrees with the commenter's suggestions and rationale and has made the appropriate changes in Table C2A for FFSs and in Table D2A for FTDs.

CAE and others suggested relating the proposed tolerances in Table C2A, entry 2.d.3.a, Dynamic Lateral and Directional Stability, Lateral-Directional Oscillations test. The commenters stated that the non-periodic responses may be divergent, weakly convergent, or deadbeat. The commenters stated that the proposed tolerances may be too restrictive for deadbeat responses. Additionally, the commenters stated that oscillatory responses that satisfy the period and damping ratio tolerances would not necessarily meet the proposed time history tolerances because of the non-periodic nature of the response. The rationale for these recommendations is to avoid requirements that are unduly restrictive with divergent results while ensuring that the non-periodic responses are reproduced with sufficient accuracy.

The FAA agrees with the commenters' suggestions and rationale and has made the appropriate changes in Table C2A for FFSs and in Table D2A for FTDs.

Thales, CAE, and others were concerned that there are no tolerances specified for the tests listed in Table C2A, entry 3.a, Frequency Response, 3.b, Leg Balance, and 3.c, Turn Around Check.

Because of the way the tests are used, the FAA has determined it is appropriate that these specific tests do not have a specified tolerance other than the performance as established by the FSTD manufacturer in coordination with the sponsor. These tests are conducted during the initial evaluation and made part of the MQTG. While the sponsor is not required to run these tests again during continuing qualification evaluations, the test results are available if a question arises about the performance of the motion system hardware or the integrity of the motion set-up at any time subsequent to the initial qualification evaluation. The test results recorded during the initial qualification evaluation provide a benchmark against which subsequent comparisons can be made.

CAE and others questioned whether a motion signature (Table C2A, entry 3.e, Motion Cueing Performance Signature) is required for a test that only requires a snapshot test result or a series of snapshot test results, and if a sponsor may submit a result of their choice if multiple results are available for a specific test.

The specific motion cueing performance signature tests have specifically associated tests that are indicated in the Information/Notes column. When these tests are conducted, the sponsor records the motion system as an additional parameter, providing a cross-sectional benchmark for the motion system performance. When the test authorizes the result to be provided as “a series of snapshot tests,” the sponsor may choose to record the motion cueing performance signature tests as a time history or as a series of snapshot tests.

Thales, HAI, and others requested that sponsors be allowed to use alternative data sources for Helicopter FTDs, as authorized for Airplane FTDs.

At this time, alternative data source information has not been developed for Helicopter FTDs. The FAA developed the alternative data source information for airplanes in coordination with industry prior to this rulemaking. Anyone interested in researching and developing alternatives for helicopter FTDs for future rulemakings should contact the NSPM.

The HAI and others suggested expanding the vertical field-of-view requirements for level 7 helicopter FTDs to at least 70° in paragraph 24 of Appendix D, Helicopter Flight Training Devices. CAE further noted that the field-of-view requirements for Level 7 FTDs appear to be more stringent than the requirements for a Level B simulator.

Peripheral vision is a critical cue in helicopter operations. Therefore, the FAA determined that the field-of-view standards for Level C helicopter simulators, which have been in effect since 1994, provide the adequate peripheral cues for the new level 7 helicopter FTD. Because peripheral vision is the critical cue, the FAA has not expanded the vertical field-of-view requirement.

CAE and others suggested revising the requirements for handling qualities for the level 7 helicopter FTD listed in Table D1A, given the list of tasks that may be authorized for the FTD.

Although the tasks listed in the referenced table may seem extensive for a device that is not an FFS, the FAA Start Printed Page 26487does not intend that a student would be completely trained or trained to proficiency in any of the tasks authorized for that FTD. In each case, the task requires additional training, either in an aircraft or in a higher level FSTD, and a proficiency test in an aircraft or in a higher level FSTD upon completion of such training. Therefore, the FAA has not revised the handling qualities for the level 7 helicopter FTD.

CAE and others suggested modifying Table D1A, entries 1.a and 1.b, to clarify the location of bulkheads and the location and operation of circuit breakers.

The FAA has included clarifying language in entry 1.a of Table D1A.

CAE and others suggested removing the statement “An SOC is required” from Table D1A, entries 1.a, 1.b, 2.a, 6.a.1, 6.a.2, 6.a.3, 6.a.4, 6.a.5, 6.a.6, and 6.b.

The FAA agrees with the commenters with respect to entries 1.a and 1.b and has removed the SOC statement because a visual observation is sufficient. However, for the remainder of the entries, the SOC statements are still necessary because a visual observation will not reveal the data necessary to demonstrate and explain compliance with the specific requirements.

CAE and others suggested including a requirement for an SOC to explain how the computer will address the delay timing requirements for relative responses in Table D1A, entry 2.c.

The entry preceding 2.c sets forth the requirement to have a computer (analog or digital) with the capabilities necessary to meet the qualification level sought. At this point, an SOC is required. The SOC will supply the information about the delay timing tests. Therefore, an additional SOC requirement in entry 2.c is not necessary.

CAE, HAI, and others suggested requiring in Table D1A, entry 5, Motion system, that all FTD levels have a motion system instead of allowing an open authorization with the limitation that, if installed, it may not be distracting.

The current training equipment for helicopter FTDs is not designed to include motion systems. The FAA recognizes, however, that some sponsors may wish to include these systems as part of their training equipment. If a sponsor elects to install a motion system, the system must not be distracting. Further, if the system will be used for additional training, testing, or checking credits, it must meet certain other requirements outlined in Appendix C. Accordingly, the FAA has not required helicopter FTDs to have motion systems. However, as proposed, all level 7 FTDs are required, at the very least, to have a vibration system.

HAI and others questioned why “mast bumping” was not authorized for Level 6 FTDs, as it is for Level 7 FTDs.

As noted in entry 5.b of Table D1A, only Level 7 FTDs are required to have a vibration system. Because the primary cue that would alert the pilot to the onset of mast bumping would be an increase in the vibration felt from the rotor system, this task is only authorized for Level 7 FTDs.

CAE stated that in Table D2A, entry 2.b.3.d, Vertical Control Response, the augmentation condition under the flight condition column is not specified, which is different from the previous three tests for control response in that table.

The FAA agrees with the commenter and has amended the referenced flight condition column to indicate that the augmentation condition for the test is both on and off, as it is for the preceding three control response tests in Table D2A.

CAE and others questioned whether the requirements of FSTD Directive 1 should be extended to helicopter FTDs.

The provisions of FSTD Directive 1 are applicable to those FSTD airport models currently in existence. Currently, there are no helicopter FTDs that have required visual systems. Therefore, there is no need to extend the requirements set out in FSTD Directive 1 to helicopter FTDs. The requirements for airport models are included in attachment 3 of Appendix D and are applicable to newly qualified Level 7 helicopter FTDs.

HAI and others questioned the necessity and cost of requiring Table D3B, entry 5.f, Effect of Rain Removal Devices.

The visual system requirement for the Level 7 helicopter FTD was designed to mirror the Level C helicopter FFS visual system requirement, which includes rain removal devices. This requirement is necessary to ensure that the FTD adequately reflects the actual helicopter being simulated. If the actual helicopter does not have rain removal devices, the FTD is not required to demonstrate the effect of rain removal devices. The FAA notes that these devices are not always a ``windshield wiper,'' but may be high-pressure air or an application of rain-repelling fluid.

E. Quality Management System (QMS)

Federal Express, ATA, and others questioned which Quality Management System (QMS) would apply when an FSTD (including FSTDs owned by foreign entities), is installed in a Training Center with a different QMS, or if the FSTD is maintained by a contractor with a different QMS.

The system and processes outlined in the QMS should enable the sponsor to monitor compliance with all applicable regulations and ensure correct maintenance and performance of the FSTD in accordance with part 60. Thus, the sponsor's QMS must include provisions to ensure that the FSTD will only be used when it is in compliance with the sponsor's own QMS and the regulatory requirements of part 60.

The ATA, Rockwell Collins, and others requested that the voluntary elements for the QMS, as published on October 30, 2006 (71 FR 63426), be included in Appendix E of the final rule. One commenter suggested that the concept of a ``basic'' and a ``voluntary'' QMS be removed and a single QMS be required.

As noted in the NPRM (72 FR 59604), the FAA removed the voluntary QMS from Appendix E. As proposed, Appendix E sets forth the basic requirements for a QMS. Although commenters requested that we include in part 60 the voluntary program, the voluntary program does not expand, further explain, or correspond to specific regulatory requirements. Therefore, the FAA has not included the voluntary program in the final rule.

The ATA, Northwest, and others questioned the inspection responsibilities of the NSPM in evaluating the QMS as opposed to FAA entities conducting ATOS audits.

The NSPM is responsible for evaluating the FSTD, including the QMS associated with the FSTD. The ATOS inspections determine whether the incorporation of the FSTD into an FAA-approved flight training program provides the necessary tool(s) to complete the required training program activities. The FAA has determined that the ATOS inspections will not include review of the actual FSTD or the QMS associated with that FSTD.

Federal Express and others questioned whether only the Management Representative (MR) should receive Quality System training and brief other personnel on procedures and suggested that the wording be changed to allow others, besides the MR, to brief other personnel. They were also concerned that the MR, in most cases, is the Director of Operations. They also questioned what would be considered ``appropriate'' quality system training.

The FAA does not require that the MR be the Director of Operations or hold any other specific position for a certificate holder. The MR, as Start Printed Page 26488determined by the sponsor, may delegate his or her responsibilities so long as the delegation does not compromise the QMS. If the MR delegates his or her responsibilities, the MR must ensure that the person to whom the MR delegates his or her responsibilities is capable of adequately briefing other personnel on QMS procedures. Further, anyone can receive QMS training. The FAA, however, is requiring only that the MR receive QMS training. The FAA agrees that the word ``appropriate'' is not necessary in this context and has removed it.

Federal Express and others questioned the proposed requirement to notify the NSPM within 10 working days of the sponsor becoming aware of an addition to, or revision of, flight-related data or airplane systems-related data used to program or operate a qualified FSTD. The commenters are concerned because systems data may not be provided to the sponsor in a timely manner. They requested the notification time be changed to 10 working days of performing a modification, an addition, or a revision of FSTD software that affects the flight or system operations of a qualified FSTD.

The requirement that the sponsor must submit notification within 10 calendar days is only a statement that the sponsor is aware that an addition to, amendment of, or a revision of data that may relate to FFS performance or handling characteristics is available. This notification does not require any information regarding how the change is to be accomplished, nor does it commit the sponsor to implementing the particular change. Rather, information regarding the sponsor's proposed course of action must be submitted within 45 calendar days of the sponsor becoming aware of the data. Therefore, the FAA did not change the notification time requirement as requested by the commenters.

The ATA and others suggested the FAA set forth the minimum requirements for a discrepancy prioritization system or include a note in Appendix E (QMS Systems) that a prioritization system is a required element in an acceptable QMS.

There is no requirement for the development or the implementation of a discrepancy prioritization system for the correction of FSTD discrepancies. Such a system is completely voluntary. If the sponsor elects to develop such a system, the NSPM must approve the system. As stated in Note 1 to entry E1.31.b of Appendix E, if a sponsor has an approved prioritization system, the QMS must describe how discrepancies are prioritized, what actions are taken, and how the sponsor will notify the NSPM if a missing, malfunctioning, or inoperative component (MMI) has not been repaired or replaced within the specified timeframe. Because this prioritization system is voluntary, the FAA has not adopted the changes.

F. Miscellaneous

United, the ATA, and others suggested that the FAA clarify and confirm that elements of the QPS appendices that go beyond current requirements not apply to FSTDs qualified before May 30, 2008. Also, the commenters recommended continuing to allow currently qualified FSTDs to be updated under the guidance effective when the simulator was initially qualified.

Except for FSTD Directive 1, the rule as proposed does not require currently qualified FSTDs to meet the requirements of the QPS Appendices A-D, attachments 1, 2, and 3, as long as the FSTD continues to meet the test requirements of its original qualification (see paragraph 13, subparagraph b of Appendices A-D). In response to comments, the FAA has clarified that FSTD updates will continue to be allowed under the standards in the current Master Qualification Test Guide (MQTG) for that FSTD.

CAE and others noted that the statement ``a subjective test is required'' in Table C1A is inconsistent with international standards.

The references to ``a subjective test is required'' and ``an objective test is required'' in Tables A1A, B1A, C1A, and D1A were redundant of the requirements in Attachments 2 and 3 in Appendices A-D. Therefore, we have removed these references. The objective and subjective test requirements in Attachments 2 and 3 in Appendices A-D are consistent with international standards.

The ATA, Northwest, Boeing, CAE, and others recommended adding references to the Airplane Flight Manual (AFM) in the regulatory requirements sections of the QPS appendices.

The FAA is not referencing the AFM as requested because the AFM provides specific standards based on aircraft type. Where the AFM provides helpful data, it may be used as guidance and as an additional data source, if appropriate.

CAE and others expressed concern that correcting known data calibration errors may not be permitted because of the language contained in Appendix A, Attachment 2, paragraph 9, (FSTD) Objective Data Requirements, subparagraph b(5).

The FAA acknowledges that the correction of recognized data calibration errors is often accomplished in data collection and reduction exercises. Therefore, the FAA has added language where appropriate in Appendices A-D to permit the correction of known data calibration errors provided that an explanation of the methods used to correct the errors appears in the QTG.

CAE requested the FAA explain how percentages are calculated when tolerances are expressed as a percentage in attachment 2, paragraph 2.b, of Appendices A-D.

The FAA has included an explanation of how these percentages are calculated in Appendices A-D, attachment 2, paragraph 2.b.

The ATA, Northwest, and others expressed concern over the submission of an FSTD modification notification to the NSPM as described in Appendix A, Paragraph 17, subparagraph a. The commenters were concerned that the results of the modification might not be known until after the notice of the modification is submitted to the NSPM.

The notification is not intended to be a detailed summary of each specific result. The notification must simply include a plan of action and a general description of the expected results.

The ATA, Rockwell Collins, and others requested clarification of the use of the term MMI component. Some sought clarification as to whether an MMI component was a hardware component, a software component, or a component that directly affected the training mission of the FSTD. In addition, some commenters requested an inclusive list of components such as: Flight deck hardware, a system line replaceable unit (LRU) of hardware or software, or a major FSTD system. Further, commenters asked who is responsible for determining whether an MMI component is necessary for a particular maneuver, procedure, or task.

The FAA has determined it is unnecessary to further clarify the meaning of missing, malfunctioning, or inoperative component. These words have their typical dictionary meanings. In this rule, an FSTD component could be a piece of hardware, a piece of software that performs as a piece of hardware (e.g., software functioning as an autopilot), or a piece of software that is used in the operation of the simulated aircraft or of the FSTD itself. Each FSTD component is present to serve a purpose—whether that purpose is to allow the simulation to work or to simulate a component of the aircraft being simulated. Since an FSTD is used to train, test, or check flight crewmembers, if one or more Start Printed Page 26489component of the FSTD becomes missing, is not working, or is not working correctly, there would be some impact on the function of the FSTD. Developing an inclusive list of components that are necessary for a particular maneuver, procedure, or task is impractical because of the unique characteristics of each FSTD and unnecessary because of the obvious nature and effect of an MMI component on the overall operation of the FSTD. We have added language to the information in paragraph 18, Operation with Missing, Malfunctioning, or Inoperative Components (§ 60.25) in Appendices A-D to clarify that it is the responsibility of the instructor, check airman, or representative of the administrator conducting training, testing, or checking, to exercise reasonable and prudent judgment to determine whether an MMI component is necessary for a particular maneuver, procedure, or task.

Boeing and others commented on the repetition of the definitions of the weight ranges (near maximum, medium, and light). In addition to appearing in Appendix F, the definitions also appear in Attachment 2 of Appendices A-D. The commenters are concerned that the repetition may cause confusion in the application of these ranges. Further, CAE stated that the terms may not apply to light-class helicopters.

The FAA has removed the definitions of these terms from the QPS Requirement in Appendices A-D because they are defined in Appendix F. In some cases, these gross weight ranges are not within the appropriate ranges for light-class helicopters. Therefore, in Appendices C and D, we have added a statement that these terms may not be appropriate for light-class helicopters. Prior coordination with the NSPM is required to determine the acceptable gross weight ranges for light-class helicopters.

The ATA, Northwest, and others questioned how the FAA could use Personally Identifiable Information (PII) for investigation, compliance, or enforcement purposes and then bring enforcement action against a person, not certificated by the FAA, who may have worked on an FSTD.

The FAA must ensure that FSTDs used by flight crewmembers for training, testing, and checking purposes are maintained and used properly and in accordance with all regulatory requirements. If the FAA finds grounds for investigation or enforcement action, the FAA may request, administratively subpoena, or seek a court order for the sponsor's records, which may contain PII. The FAA may use those records, and any PII contained therein, in the course of inspection, investigation, and enforcement. Furthermore, if, for example, the FAA discovered during the course of such an investigation that an individual made false or misleading statements, the FAA could use its statutory and regulatory authority to issue a cease and desist order to prohibit the individual from conducting any future maintenance on any FSTD, regardless of whether he or she holds an FAA certificate.

Paperwork Reduction Act

Information collection requirements associated with this final rule have been approved previously by the Office of Management and Budget (OMB) under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) and have been assigned OMB Control Number 2120-0680.

International Compatibility

In keeping with U.S. obligations under the Convention on International Civil Aviation, it is FAA policy to comply with ICAO Standards and Recommended Practices to the maximum extent practicable. The FAA has reviewed the corresponding ICAO Standards and Recommended Practices and has identified no differences with these regulations.

III. Regulatory Evaluation, Regulatory Flexibility Determination, International Trade Impact Assessment, and Unfunded Mandates Assessment

Changes to Federal regulations must undergo several economic analyses. First, Executive Order 12866 directs that each Federal agency shall propose or adopt a regulation only upon a reasoned determination that the benefits of the intended regulation justify its costs. Second, the Regulatory Flexibility Act of 1980 (Pub. L. 96-354) requires agencies to analyze the economic impact of regulatory changes on small entities. Third, the Trade Agreements Act (Pub. L. 96-39) prohibits agencies from setting standards that create unnecessary obstacles to the foreign commerce of the United States. In developing U.S. standards, the Trade Act requires agencies to consider international standards and, where appropriate, that they be the basis of U.S. standards. Fourth, the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4) requires agencies to prepare a written assessment of the costs, benefits, and other effects of proposed or final rules that include a Federal mandate likely to result in the expenditure by State, local, or tribal governments, in the aggregate, or by the private sector, of $100 million or more annually (adjusted for inflation with base year of 1995). This portion of the preamble summarizes the FAA's analysis of the economic impacts of this rule.

Department of Transportation Order DOT 2100.5 prescribes policies and procedures for simplification, analysis, and review of regulations. If the expected cost impact is so minimal that a proposed or final rule does not warrant a full evaluation, this order permits that a statement to that effect and the basis for it to be included in the preamble. Such a determination has been made for this final rule. The reasoning for this determination follows:

This final rule codifies existing practice by requiring all existing FSTD visual scenes beyond the number required for qualification to meet specified requirements. The final rule also reorganizes certain sections of the QPS appendices and provides additional information on validation tests, established parameters for tolerances, acceptable data formats, and the use of alternative data sources. The changes ensure that the training and testing environment is accurate and realistic, codify existing practice, and provide greater harmonization with the international standards document for simulation. Except for the amendment to codify existing practice regarding certain visual scene requirements, these technical requirements do not apply to simulators qualified before May 30, 2008. The impact of this final rule results in minimal to no cost increases for manufacturers and sponsors.

The FAA has, therefore, determined that this rule is not a “significant regulatory action” as defined in section 3(f) of Executive Order 12866, and is not “significant” as defined in DOT's Regulatory Policies and Procedures.

Regulatory Flexibility Determination

The Regulatory Flexibility Act of 1980 (Pub. L. 96-354) (RFA) establishes “as a principle of regulatory issuance that agencies shall endeavor, consistent with the objectives of the rule and of applicable statutes, to fit regulatory and informational requirements to the scale of the businesses, organizations, and governmental jurisdictions subject to regulation. To achieve this principle, agencies are required to solicit and consider flexible regulatory proposals and to explain the rationale for their actions to assure that such proposals are given serious consideration.” The RFA covers a wide range of small entities, including small businesses, not-for-profit organizations, and small governmental jurisdictions. Start Printed Page 26490

Agencies must perform a review to determine whether a rule will have a significant economic impact on a substantial number of small entities. If the agency determines that it will, the agency must prepare a regulatory flexibility analysis as described in the RFA.

However, if an agency determines that a rule is not expected to have a significant economic impact on a substantial number of small entities, section 605(b) of the RFA provides that the head of the agency may so certify and a regulatory flexibility analysis is not required. The certification must include a statement providing the factual basis for this determination, and the reasoning should be clear.

This final rule codifies existing practice by requiring all existing FSTD visual scenes beyond the number required for qualification to meet specified requirements. The final rule also reorganizes certain sections of the QPS appendices and provides additional information on validation tests, established parameters for tolerances, acceptable data formats, and the use of alternative data sources. The changes ensure that the training and testing environment is accurate and more realistic, codify existing practice, and provide greater harmonization with the international standards document for simulation. Except for the amendment to codify existing practice regarding certain visual scene requirements, these technical requirements do not apply to simulators qualified before May 30, 2008. The impact of this rule results in minimal or no cost for manufacturers and sponsors. Therefore, as the individual delegated with authority to sign this final rule on behalf of the Acting Administrator of the FAA, I certify that this rule does not have a significant economic impact on a substantial number of small entities.

International Trade Impact Assessment

The Trade Agreements Act of 1979 (Pub. L. 96-39) prohibits Federal agencies from establishing any standards or engaging in related activities that create unnecessary obstacles to the foreign commerce of the United States. Legitimate domestic objectives, such as safety, are not considered unnecessary obstacles. The statute also requires consideration of international standards and, where appropriate, that they be the basis for U.S. standards. The FAA has assessed the effect of this rule and has determined that it imposes the same costs on domestic and international entities and thus has a neutral trade impact.

Unfunded Mandates Assessment

Title II of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4) requires each Federal agency to prepare a written statement assessing the effects of any Federal mandate in a proposed or final agency rule that may result in an expenditure of $100 million or more (adjusted annually for inflation with the base year 1995) in any one year by State, local, and tribal governments, in the aggregate, or by the private sector; such a mandate is deemed to be a “significant regulatory action.” The FAA currently uses an inflation-adjusted value of $136.1 million in lieu of $100 million. This rule does not contain such a mandate.

Executive Order 13132, Federalism

The FAA has analyzed this final rule under the principles and criteria of Executive Order 13132, Federalism. We determined that this action will not have a substantial direct effect on the States, or the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government, and, therefore, does not have federalism implications.

Environmental Analysis

FAA Order 1050.1E identifies FAA actions that are categorically excluded from preparation of an environmental assessment or environmental impact statement under the National Environmental Policy Act in the absence of extraordinary circumstances. The FAA has determined this proposed rule action qualifies for the categorical exclusion identified in paragraph 312f and involves no extraordinary circumstances.

Regulations That Significantly Affect Energy Supply, Distribution, or Use

The FAA has analyzed this proposed rule under Executive Order 13211, Actions Concerning Regulations that Significantly Affect Energy Supply, Distribution, or Use (May 18, 2001). We have determined that it is not a “significant energy action” under the executive order because it is not a “significant regulatory action” under Executive Order 12866, and it is not likely to have a significant adverse effect on the supply, distribution, or use of energy.

6. Sponsor Qualification Requirements (§ 60.7)

Begin Information

a. The intent of the language in § 60.7(b) is to have a specific FFS, identified by the sponsor, used at least once in an FAA-approved flight training program for the airplane simulated during the 12-month period described. The identification of the specific FFS may change from one 12-month period to the next 12-month period as long as the sponsor sponsors and uses at least one FFS at least once during the prescribed period. No minimum number of hours or minimum FFS periods are required.

b. The following examples describe acceptable operational practices:

(1) Example One.

(a) A sponsor is sponsoring a single, specific FFS for its own use, in its own facility or elsewhere—this single FFS forms the basis for the sponsorship. The sponsor uses that FFS at least once in each 12-month period in the sponsor's FAA-approved flight training program for the airplane simulated. This 12-month period is established according to the following schedule:

(i) If the FFS was qualified prior to May 30, 2008, the 12-month period begins on the date of the first continuing qualification evaluation conducted in accordance with § 60.19 after May 30, 2008, and continues for each subsequent 12-month period;

(ii) A device qualified on or after May 30, 2008, will be required to undergo an initial or upgrade evaluation in accordance with § 60.15. Once the initial or upgrade evaluation is complete, the first continuing qualification evaluation will be conducted within 6 months. The 12-month continuing qualification evaluation cycle begins on that date and continues for each subsequent 12-month period.

(b) There is no minimum number of hours of FFS use required.

(c) The identification of the specific FFS may change from one 12-month period to the next 12-month period as long as the sponsor sponsors and uses at least one FFS at least once during the prescribed period.

(2) Example Two.

(a) A sponsor sponsors an additional number of FFSs, in its facility or elsewhere. Each additionally sponsored FFS must be—

(i) Used by the sponsor in the sponsor's FAA-approved flight training program for the airplane simulated (as described in § 60.7(d)(1));

  OR

(ii) Used by another FAA certificate holder in that other certificate holder's FAA-approved flight training program for the airplane simulated (as described in § 60.7(d)(1)). This 12-month period is established in the same manner as in example one;

  OR

(iii) Provided a statement each year from a qualified pilot (after having flown the airplane, not the subject FFS or another FFS, during the preceding 12-month period), stating that the subject FFS's performance and handling qualities represent the airplane (as described in § 60.7(d)(2)). This statement is provided at least once in each 12-month period established in the same manner as in example one.

(b) No minimum number of hours of FFS use is required.

(3) Example Three.

(a) A sponsor in New York (in this example, a Part 142 certificate holder) establishes “satellite” training centers in Chicago and Moscow.

(b) The satellite function means that the Chicago and Moscow centers must operate under the New York center's certificate (in accordance with all of the New York center's practices, procedures, and policies; e.g., instructor and/or technician training/checking requirements, record keeping, QMS program).

(c) All of the FFSs in the Chicago and Moscow centers could be dry-leased (i.e., the certificate holder does not have and use FAA-approved flight training programs for the FFSs in the Chicago and Moscow centers) because—

(i) Each FFS in the Chicago center and each FFS in the Moscow center is used at least once each 12-month period by another FAA certificate holder in that other certificate holder's FAA-approved flight training program for the airplane (as described in § 60.7(d)(1));

  OR

(ii) A statement is obtained from a qualified pilot (having flown the airplane, not the subject FFS or another FFS, during the preceding 12-month period) stating that the performance and handling qualities of each FFS in the Chicago and Moscow centers represents the airplane (as described in § 60.7(d)(2)).

9. FFS Objective Data Requirements (§ 60.13)

Begin QPS Requirements

a. Flight test data used to validate FFS performance and handling qualities must have been gathered in accordance with a flight test program containing the following:

(1) A flight test plan consisting of:

(a) The maneuvers and procedures required for aircraft certification and simulation programming and validation.

(b) For each maneuver or procedure—

(i) The procedures and control input the flight test pilot and/or engineer used.

(ii) The atmospheric and environmental conditions.

(iii) The initial flight conditions.

(iv) The airplane configuration, including weight and center of gravity.

(v) The data to be gathered.

(vi) All other information necessary to recreate the flight test conditions in the FFS.

(2) Appropriately qualified flight test personnel.

(3) An understanding of the accuracy of the data to be gathered using appropriate alternative data sources, procedures, and instrumentation that is traceable to a recognized standard as described in Attachment 2, Table A2E of this appendix.

(4) Appropriate and sufficient data acquisition equipment or system(s), including appropriate data reduction and analysis methods and techniques, as would be acceptable to the FAA's Aircraft Certification Service.

b. The data, regardless of source, must be presented as follows:

(1) In a format that supports the FFS validation process.

(2) In a manner that is clearly readable and annotated correctly and completely.

(3) With resolution sufficient to determine compliance with the tolerances set forth in Attachment 2, Table A2A of this appendix.

(4) With any necessary instructions or other details provided, such as yaw damper or throttle position. Start Printed Page 26493

(5) Without alteration, adjustments, or bias. Data may be corrected to address known data calibration errors provided that an explanation of the methods used to correct the errors appears in the QTG. The corrected data may be re-scaled, digitized, or otherwise manipulated to fit the desired presentation.

c. After completion of any additional flight test, a flight test report must be submitted in support of the validation data. The report must contain sufficient data and rationale to support qualification of the FFS at the level requested.

d. As required by § 60.13(f), the sponsor must notify the NSPM when it becomes aware that an addition to, an amendment to, or a revision of data that may relate to FFS performance or handling characteristics is available. The data referred to in this paragraph is data used to validate the performance, handling qualities, or other characteristics of the aircraft, including data related to any relevant changes occurring after the type certificate was issued. The sponsor must—

(1) Within 10 calendar days, notify the NSPM of the existence of this data; and

(2) Within 45 calendar days, notify the NSPM of—

(a) The schedule to incorporate this data into the FFS; or

(b) The reason for not incorporating this data into the FFS.

e. In those cases where the objective test results authorize a “snapshot test” or a “series of snapshot tests” results in lieu of a time-history result, the sponsor or other data provider must ensure that a steady state condition exists at the instant of time captured by the “snapshot.” The steady state condition must exist from 4 seconds prior to, through 1 second following, the instant of time captured by the snapshot.

f. The FFS sponsor is encouraged to maintain a liaison with the manufacturer of the aircraft being simulated (or with the holder of the aircraft type certificate for the aircraft being simulated if the manufacturer is no longer in business), and, if appropriate, with the person having supplied the aircraft data package for the FFS in order to facilitate the notification required by § 60.13(f).

g. It is the intent of the NSPM that for new aircraft entering service, at a point well in advance of preparation of the Qualification Test Guide (QTG), the sponsor should submit to the NSPM for approval, a descriptive document (see Table A2C, Sample Validation Data Roadmap for Airplanes) containing the plan for acquiring the validation data, including data sources. This document should clearly identify sources of data for all required tests, a description of the validity of these data for a specific engine type and thrust rating configuration, and the revision levels of all avionics affecting the performance or flying qualities of the aircraft. Additionally, this document should provide other information, such as the rationale or explanation for cases where data or data parameters are missing, instances where engineering simulation data are used or where flight test methods require further explanations. It should also provide a brief narrative describing the cause and effect of any deviation from data requirements. The aircraft manufacturer may provide this document.

h. There is no requirement for any flight test data supplier to submit a flight test plan or program prior to gathering flight test data. However, the NSPM notes that inexperienced data gatherers often provide data that is irrelevant, improperly marked, or lacking adequate justification for selection. Other problems include inadequate information regarding initial conditions or test maneuvers. The NSPM has been forced to refuse these data submissions as validation data for an FFS evaluation. It is for this reason that the NSPM recommends that any data supplier not previously experienced in this area review the data necessary for programming and for validating the performance of the FFS, and discuss the flight test plan anticipated for acquiring such data with the NSPM well in advance of commencing the flight tests.

i. The NSPM will consider, on a case-by-case basis, whether to approve supplemental validation data derived from flight data recording systems, such as a Quick Access Recorder or Flight Data Recorder.

10. Special Equipment and Personnel Requirements for Qualification of the FFSs (§ 60.14)

Begin Information

a. In the event that the NSPM determines that special equipment or specifically qualified persons will be required to conduct an evaluation, the NSPM will make every attempt to notify the sponsor at least one (1) week, but in no case less than 72 hours, in advance of the evaluation. Examples of special equipment include spot photometers, flight control measurement devices, and sound analyzers. Examples of specially qualified personnel include individuals specifically qualified to install or use any special equipment when its use is required.

b. Examples of a special evaluation include an evaluation conducted after an FFS is moved, at the request of the TPAA, or as a result of comments received from users of the FFS that raise questions about the continued qualification or use of the FFS.

(l) Simulator Objective Test Results as obtained by the sponsor. Each test result must reflect the date completed and must be clearly labeled as a product of the device being tested.

f. A convertible FFS is addressed as a separate FFS for each model and series airplane to which it will be converted and for the FAA qualification level sought. If a sponsor seeks qualification for two or more models of an airplane type using a convertible FFS, the sponsor must submit a QTG for each airplane model, or a QTG for the first airplane model and a supplement to that QTG for each additional airplane model. The NSPM will conduct evaluations for each airplane model.

g. Form and manner of presentation of objective test results in the QTG:

(1) The sponsor's FFS test results must be recorded in a manner acceptable to the NSPM, that allows easy comparison of the FFS test results to the validation data (e.g., use of a multi-channel recorder, line printer, cross plotting, overlays, transparencies).

(2) FFS results must be labeled using terminology common to airplane parameters as opposed to computer software identifications.

(3) Validation data documents included in a QTG may be photographically reduced only if such reduction will not alter the graphic scaling or cause difficulties in scale interpretation or resolution.

(4) Scaling on graphical presentations must provide the resolution necessary to evaluate the parameters shown in Attachment 2, Table A2A of this appendix.

(5) Tests involving time histories, data sheets (or transparencies thereof) and FFS test results must be clearly marked with appropriate reference points to ensure an accurate comparison between the FFS and the airplane with respect to time. Time histories recorded via a line printer are to be clearly identified for cross plotting on the airplane data. Over-plots must not obscure the reference data.

h. The sponsor may elect to complete the QTG objective and subjective tests at the manufacturer's facility or at the sponsor's training facility. If the tests are conducted at the manufacturer's facility, the sponsor must repeat at least one-third of the tests at the sponsor's training facility in order to substantiate FFS performance. The QTG must be clearly annotated to indicate when and where each test was accomplished. Tests conducted at the manufacturer's facility and at the sponsor's training facility must be conducted after the FFS is assembled with systems and sub-systems functional and operating in an interactive manner. The test results must be submitted to the NSPM.

i. The sponsor must maintain a copy of the MQTG at the FFS location.

j. All FFSs for which the initial qualification is conducted after May 30, 2014, must have an electronic MQTG (eMQTG) including all objective data obtained from airplane testing, or another approved source (reformatted or digitized), together with correlating objective test results obtained from the performance of the FFS (reformatted or digitized) as prescribed in this appendix. The eMQTG must also contain the general FFS performance or demonstration results (reformatted or digitized) prescribed in this appendix, and a description of the equipment necessary to perform the initial qualification evaluation and the continuing qualification evaluations. The eMQTG must include the original validation data used to validate FFS performance and handling qualities in either the original digitized format from the data supplier or an electronic scan of the original time-history plots that were provided by the data supplier. A copy of the eMQTG must be provided to the NSPM.

k. All other FFSs not covered in subparagraph “j” must have an electronic copy of the MQTG by May 30, 2014. An electronic copy of the MQTG must be provided to the NSPM. This may be provided by an electronic scan presented in a Portable Document File (PDF), or similar format acceptable to the NSPM.

l. During the initial (or upgrade) qualification evaluation conducted by the NSPM, the sponsor must also provide a person who is a user of the device (e.g., a qualified pilot or instructor pilot with flight time experience in that aircraft) and knowledgeable about the operation of the aircraft and the operation of the FFS.

End QPS Requirements

Begin Information

m. Only those FFSs that are sponsored by a certificate holder as defined in Appendix F of this part will be evaluated by the NSPM. However, other FFS evaluations may be conducted on a case-by-case basis as the Administrator deems appropriate, but only in accordance with applicable agreements.

n. The NSPM will conduct an evaluation for each configuration, and each FFS must be evaluated as completely as possible. To ensure a thorough and uniform evaluation, each FFS is subjected to the general simulator requirements in Attachment 1 of this appendix, the objective tests listed in Attachment 2 of this appendix, and the subjective tests listed in Attachment 3 of this appendix. The evaluations described herein will include, but not necessarily be limited to the following:

(1) Airplane responses, including longitudinal and lateral-directional control responses (see Attachment 2 of this appendix);

(2) Performance in authorized portions of the simulated airplane's operating envelope, to include tasks evaluated by the NSPM in the areas of surface operations, takeoff, climb, cruise, descent, approach, and landing as well as abnormal and emergency operations (see Attachment 2 of this appendix);

(3) Control checks (see Attachment 1 and Attachment 2 of this appendix);

(4) Flight deck configuration (see Attachment 1 of this appendix);

(5) Pilot, flight engineer, and instructor station functions checks (see Attachment 1 and Attachment 3 of this appendix);

(6) Airplane systems and sub-systems (as appropriate) as compared to the airplane simulated (see Attachment 1 and Attachment 3 of this appendix);

(7) FFS systems and sub-systems, including force cueing (motion), visual, and aural (sound) systems, as appropriate (see Attachment 1 and Attachment 2 of this appendix); and

(8) Certain additional requirements, depending upon the qualification level sought, including equipment or circumstances that may become hazardous to the occupants. The sponsor may be subject to Occupational Safety and Health Administration requirements.

o. The NSPM administers the objective and subjective tests, which includes an examination of functions. The tests include a qualitative assessment of the FFS by an NSP pilot. The NSP evaluation team leader may assign other qualified personnel to assist in accomplishing the functions examination and/or the objective and subjective tests performed during an evaluation when required.

(1) Objective tests provide a basis for measuring and evaluating FFS performance and determining compliance with the requirements of this part. Start Printed Page 26495

(2) Subjective tests provide a basis for:

(a) Evaluating the capability of the FFS to perform over a typical utilization period;

(b) Determining that the FFS satisfactorily simulates each required task;

(c) Verifying correct operation of the FFS controls, instruments, and systems; and

(d) Demonstrating compliance with the requirements of this part.

p. The tolerances for the test parameters listed in Attachment 2 of this appendix reflect the range of tolerances acceptable to the NSPM for FFS validation and are not to be confused with design tolerances specified for FFS manufacture. In making decisions regarding tests and test results, the NSPM relies on the use of operational and engineering judgment in the application of data (including consideration of the way in which the flight test was flown and the way the data was gathered and applied), data presentations, and the applicable tolerances for each test.

q. In addition to the scheduled continuing qualification evaluation, each FFS is subject to evaluations conducted by the NSPM at any time without prior notification to the sponsor. Such evaluations would be accomplished in a normal manner (i.e., requiring exclusive use of the FFS for the conduct of objective and subjective tests and an examination of functions) if the FFS is not being used for flight crewmember training, testing, or checking. However, if the FFS were being used, the evaluation would be conducted in a non-exclusive manner. This non-exclusive evaluation will be conducted by the FFS evaluator accompanying the check airman, instructor, Aircrew Program Designee (APD), or FAA inspector aboard the FFS along with the student(s) and observing the operation of the FFS during the training, testing, or checking activities.

r. Problems with objective test results are handled as follows:

(1) If a problem with an objective test result is detected by the NSP evaluation team during an evaluation, the test may be repeated or the QTG may be amended.

(2) If it is determined that the results of an objective test do not support the level requested but do support a lower level, the NSPM may qualify the FFS at that lower level. For example, if a Level D evaluation is requested and the FFS fails to meet sound test tolerances, it could be qualified at Level C.

s. After an FFS is successfully evaluated, the NSPM issues a Statement of Qualification (SOQ) to the sponsor. The NSPM recommends the FFS to the TPAA, who will approve the FFS for use in a flight training program. The SOQ will be issued at the satisfactory conclusion of the initial or continuing qualification evaluation and will list the tasks for which the FFS is qualified, referencing the tasks described in Table A1B in Attachment 1 of this appendix. However, it is the sponsor's responsibility to obtain TPAA approval prior to using the FFS in an FAA-approved flight training program.

t. Under normal circumstances, the NSPM establishes a date for the initial or upgrade evaluation within ten (10) working days after determining that a complete QTG is acceptable. Unusual circumstances may warrant establishing an evaluation date before this determination is made. A sponsor may schedule an evaluation date as early as 6 months in advance. However, there may be a delay of 45 days or more in rescheduling and completing the evaluation if the sponsor is unable to meet the scheduled date. See Attachment 4 of this appendix, Figure A4A, Sample Request for Initial, Upgrade, or Reinstatement Evaluation.

u. The numbering system used for objective test results in the QTG should closely follow the numbering system set out in Attachment 2 of this appendix, FFS Objective Tests, Table A2A.

v. Contact the NSPM or visit the NSPM Web site for additional information regarding the preferred qualifications of pilots used to meet the requirements of § 60.15(d).

w. Examples of the exclusions for which the FFS might not have been subjectively tested by the sponsor or the NSPM and for which qualification might not be sought or granted, as described in § 60.15(g)(6), include windshear training and circling approaches.

Begin QPS Requirements

a. In instances where a sponsor plans to remove an FFS from active status for a period of less than two years, the following procedures apply:

(1) The NSPM must be notified in writing and the notification must include an estimate of the period that the FFS will be inactive;

(2) Continuing Qualification evaluations will not be scheduled during the inactive period;

(3) The NSPM will remove the FFS from the list of qualified FSTDs on a mutually established date not later than the date on which the first missed continuing qualification evaluation would have been scheduled;

(4) Before the FFS is restored to qualified status, it must be evaluated by the NSPM. The evaluation content and the time required to accomplish the evaluation is based on the number of continuing qualification evaluations and sponsor-conducted quarterly inspections missed during the period of inactivity.

(5) The sponsor must notify the NSPM of any changes to the original scheduled time out of service;

b. Simulators qualified prior to May 30, 2008, are not required to meet the general simulation requirements, the objective test requirements or the subjective test requirements of attachments 1, 2, and 3 of this appendix as long as the simulator continues to meet the test requirements contained in the MQTG developed under the original qualification basis.

c. After May 30, 2009, each visual scene or airport model beyond the minimum required for the FFS qualification level that is installed in and available for use in a qualified FFS must meet the requirements described in attachment 3 of this appendix.

d. Simulators qualified prior to May 30, 2008, may be updated. If an evaluation is deemed appropriate or necessary by the NSPM after such an update, the evaluation will not require an evaluation to standards beyond those against which the simulator was originally qualified.

End QPS Requirements

Begin Information

e. Other certificate holders or persons desiring to use an FFS may contract with FFS sponsors to use FFSs previously qualified at a particular level for an airplane type and approved for use within an FAA-approved flight training program. Such FFSs are not required to undergo an additional qualification process, except as described in § 60.16.

f. Each FFS user must obtain approval from the appropriate TPAA to use any FFS in an FAA-approved flight training program.

g. The intent of the requirement listed in § 60.17(b), for each FFS to have a SOQ within 6 years, is to have the availability of that statement (including the configuration list and the limitations to authorizations) to provide a complete picture of the FFS inventory regulated by the FAA. The issuance of the statement will not require any additional evaluation or require any adjustment to the evaluation basis for the FFS.

h. Downgrading of an FFS is a permanent change in qualification level and will necessitate the issuance of a revised SOQ to reflect the revised qualification level, as appropriate. If a temporary restriction is placed on an FFS because of a missing, malfunctioning, or inoperative component or on-going repairs, the restriction is not a permanent change in qualification level. Instead, the restriction is temporary and is removed when the reason for the restriction has been resolved.

i. The NSPM will determine the evaluation criteria for an FFS that has been removed from active status. The criteria will be based on the number of continuing qualification evaluations and quarterly inspections missed during the period of inactivity. For example, if the FFS were out of service for a 1 year period, it would be necessary to complete the entire QTG, since all of the quarterly evaluations would have been missed. The NSPM will also consider how the FFS was stored, whether parts were removed from the FFS and whether the FFS was disassembled.

j. The FFS will normally be requalified using the FAA-approved MQTG and the criteria that was in effect prior to its removal from qualification. However, inactive periods of 2 years or more will require requalification under the standards in effect and current at the time of requalification. Start Printed Page 26496

14. Inspection, Continuing Qualification Evaluation, and Maintenance Requirements (§ 60.19)

Begin QPS Requirements

a. The sponsor must conduct a minimum of four evenly spaced inspections throughout the year. The objective test sequence and content of each inspection must be developed by the sponsor and must be acceptable to the NSPM.

b. The description of the functional preflight check must be contained in the sponsor's QMS.

c. Record “functional preflight” in the FFS discrepancy log book or other acceptable location, including any item found to be missing, malfunctioning, or inoperative.

d. During the continuing qualification evaluation conducted by the NSPM, the sponsor must also provide a person knowledgeable about the operation of the aircraft and the operation of the FFS.

e. The NSPM will conduct continuing qualification evaluations every 12 months unless:

(1) The NSPM becomes aware of discrepancies or performance problems with the device that warrants more frequent evaluations; or

(2) The sponsor implements a QMS that justifies less frequent evaluations. However, in no case shall the frequency of a continuing qualification evaluation exceed 36 months.

End QPS Requirements

Begin Information

f. The sponsor's test sequence and the content of each quarterly inspection required in § 60.19(a)(1) should include a balance and a mix from the objective test requirement areas listed as follows:

(1) Performance.

(2) Handling qualities.

(3) Motion system (where appropriate).

(4) Visual system (where appropriate).

(5) Sound system (where appropriate).

(6) Other FFS systems.

g. If the NSP evaluator plans to accomplish specific tests during a normal continuing qualification evaluation that requires the use of special equipment or technicians, the sponsor will be notified as far in advance of the evaluation as practical; but not less than 72 hours. Examples of such tests include latencies, control dynamics, sounds and vibrations, motion, and/or some visual system tests.

h. The continuing qualification evaluations, described in § 60.19(b), will normally require 4 hours of FFS time. However, flexibility is necessary to address abnormal situations or situations involving aircraft with additional levels of complexity (e.g., computer controlled aircraft). The sponsor should anticipate that some tests may require additional time. The continuing qualification evaluations will consist of the following:

(1) Review of the results of the quarterly inspections conducted by the sponsor since the last scheduled continuing qualification evaluation.

(2) A selection of approximately 8 to 15 objective tests from the MQTG that provide an adequate opportunity to evaluate the performance of the FFS. The tests chosen will be performed either automatically or manually and should be able to be conducted within approximately one-third (1/3) of the allotted FFS time.

(3) A subjective evaluation of the FFS to perform a representative sampling of the tasks set out in attachment 3 of this appendix. This portion of the evaluation should take approximately two-thirds (2/3) of the allotted FFS time.

(4) An examination of the functions of the FFS may include the motion system, visual system, sound system, instructor operating station, and the normal functions and simulated malfunctions of the airplane systems. This examination is normally accomplished simultaneously with the subjective evaluation requirements.

(1) General flight deck configuration.

(2) Simulator programming.

(3) Equipment operation.

(4) Equipment and facilities for instructor/evaluator functions.

(5) Motion system.

(6) Visual system.

(7) Sound system.

c. Table A1A provides the standards for the General Simulator Requirements.

d. Table A1B provides the tasks that the sponsor will examine to determine whether the FFS satisfactorily meets the requirements for flight crew training, testing, and experience, and provides the tasks for which the simulator may be qualified.

e. Table A1C provides the functions that an instructor/check airman must be able to control in the simulator.

f. It is not required that all of the tasks that appear on the List of Qualified Tasks (part of the SOQ) be accomplished during the initial or continuing qualification evaluation.

1.a.The simulator must have a flight deck that is a replica of the airplane simulated with controls, equipment, observable flight deck indicators, circuit breakers, and bulkheads properly located, functionally accurate and replicating the airplane. The direction of movement of controls and switches must be identical to the airplane. Pilot seats must allow the occupant to achieve the design “eye position” established for the airplane being simulated. Equipment for the operation of the flight deck windows must be included, but the actual windows need not be operable. Additional equipment such as fire axes, extinguishers, and spare light bulbs must be available in the FFS but may be relocated to a suitable location as near as practical to the original position. Fire axes, landing gear pins, and any similar purpose instruments need only be represented in silhouetteXXXXFor simulator purposes, the flight deck consists of all that space forward of a cross section of the flight deck at the most extreme aft setting of the pilots' seats, including additional required crewmember duty stations and those required bulkheads aft of the pilot seats.

However, the field-of-view is technically no less than 176°. Additional field-of-view capability may be added at the sponsor's discretion provided the minimum fields-of-view are retained.
6.e.The visual system must be free from optical discontinuities and artifacts that create non-realistic cuesXXXXNon-realistic cues might include image “swimming” and image “roll-off,” that may lead a pilot to make incorrect assessments of speed, acceleration, or situational awareness.

1. Introduction

a. For the purposes of this attachment, the flight conditions specified in the Flight Conditions Column of Table A2A of this appendix, are defined as follows:

(1) Ground—on ground, independent of airplane configuration;

(2) Take-off—gear down with flaps/slats in any certified takeoff position;

(3) First segment climb—gear down with flaps/slats in any certified takeoff position (normally not above 50 ft AGL);

(4) Second segment climb—gear up with flaps/slats in any certified takeoff position (normally between 50 ft and 400 ft AGL);

(5) Clean—flaps/slats retracted and gear up;

(6) Cruise—clean configuration at cruise altitude and airspeed;

(7) Approach—gear up or down with flaps/slats at any normal approach position as recommended by the airplane manufacturer; and

(8) Landing—gear down with flaps/slats in any certified landing position.

b. The format for numbering the objective tests in Appendix A, Attachment 2, Table A2A, and the objective tests in Appendix B, Attachment 2, Table B2A, is identical. However, each test required for FFSs is not necessarily required for FTDs. Also, each test required for FTDs is not necessarily required for FFSs. Therefore, when a test number (or series of numbers) is not required, the term “Reserved” is used in the table at that location. Following this numbering format provides a degree of commonality between the two tables and substantially reduces the potential for confusion when referring to objective test numbers for either FFSs or FTDs.

c. The reader is encouraged to review the Airplane Flight Simulator Evaluation Handbook, Volumes I and II, published by the Royal Aeronautical Society, London, UK, and AC 25-7, as amended, Flight Test Guide for Certification of Transport Category Airplanes, and AC 23-8, as amended, Flight Test Guide for Certification of Part 23 Airplanes, for references and examples regarding flight testing requirements and techniques.

d. If relevant winds are present in the objective data, the wind vector should be clearly noted as part of the data presentation, expressed in conventional terminology, and related to the runway being used for the test. Start Printed Page 26508

Begin QPS Requirements

2. Test Requirements

a. The ground and flight tests required for qualification are listed in Table A2A, FFS Objective Tests. Computer generated simulator test results must be provided for each test except where an alternative test is specifically authorized by the NSPM. If a flight condition or operating condition is required for the test but does not apply to the airplane being simulated or to the qualification level sought, it may be disregarded (e.g., an engine out missed approach for a single-engine airplane or a maneuver using reverse thrust for an airplane without reverse thrust capability). Each test result is compared against the validation data described in § 60.13 and in this appendix. Although use of a driver program designed to automatically accomplish the tests is encouraged for all simulators and required for Level C and Level D simulators, it must be possible to conduct each test manually while recording all appropriate parameters. The results must be produced on an appropriate recording device acceptable to the NSPM and must include simulator number, date, time, conditions, tolerances, and appropriate dependent variables portrayed in comparison to the validation data. Time histories are required unless otherwise indicated in Table A2A. All results must be labeled using the tolerances and units given.

b. Table A2A in this attachment sets out the test results required, including the parameters, tolerances, and flight conditions for simulator validation. Tolerances are provided for the listed tests because mathematical modeling and acquisition and development of reference data are often inexact. All tolerances listed in the following tables are applied to simulator performance. When two tolerance values are given for a parameter, the less restrictive may be used unless otherwise indicated. In those cases where a tolerance is expressed only as a percentage, the tolerance percentage applies to the maximum value of that parameter within its normal operating range as measured from the neutral or zero position unless otherwise indicated.

c. Certain tests included in this attachment must be supported with an SOC. In Table A2A, requirements for SOCs are indicated in the “Test Details” column.

d. When operational or engineering judgment is used in making assessments for flight test data applications for simulator validity, such judgment must not be limited to a single parameter. For example, data that exhibit rapid variations of the measured parameters may require interpolations or a “best fit” data selection. All relevant parameters related to a given maneuver or flight condition must be provided to allow overall interpretation. When it is difficult or impossible to match simulator to airplane data throughout a time history, differences must be justified by providing a comparison of other related variables for the condition being assessed.

e. It is not acceptable to program the FFS so that the mathematical modeling is correct only at the validation test points. Unless otherwise noted, simulator tests must represent airplane performance and handling qualities at operating weights and centers of gravity (CG) typical of normal operation. If a test is supported by airplane data at one extreme weight or CG, another test supported by airplane data at mid-conditions or as close as possible to the other extreme must be included. Certain tests that are relevant only at one extreme CG or weight condition need not be repeated at the other extreme. Tests of handling qualities must include validation of augmentation devices.

f. When comparing the parameters listed to those of the airplane, sufficient data must also be provided to verify the correct flight condition and airplane configuration changes. For example, to show that control force is within the parameters for a static stability test, data to show the correct airspeed, power, thrust or torque, airplane configuration, altitude, and other appropriate datum identification parameters must also be given. If comparing short period dynamics, normal acceleration may be used to establish a match to the airplane, but airspeed, altitude, control input, airplane configuration, and other appropriate data must also be given. If comparing landing gear change dynamics, pitch, airspeed, and altitude may be used to establish a match to the airplane, but landing gear position must also be provided. All airspeed values must be properly annotated (e.g., indicated versus calibrated). In addition, the same variables must be used for comparison (e.g., compare inches to inches rather than inches to centimeters).

g. The QTG provided by the sponsor must clearly describe how the simulator will be set up and operated for each test. Each simulator subsystem may be tested independently, but overall integrated testing of the simulator must be accomplished to assure that the total simulator system meets the prescribed standards. A manual test procedure with explicit and detailed steps for completing each test must also be provided.

h. For previously qualified simulators, the tests and tolerances of this attachment may be used in subsequent continuing qualification evaluations for any given test if the sponsor has submitted a proposed MQTG revision to the NSPM and has received NSPM approval.

i. Simulators are evaluated and qualified with an engine model simulating the airplane data supplier's flight test engine. For qualification of alternative engine models (either variations of the flight test engines or other manufacturer's engines) additional tests with the alternative engine models may be required. This attachment contains guidelines for alternative engines.

j. For testing Computer Controlled Aircraft (CCA) simulators, or other highly augmented airplane simulators, flight test data is required for the Normal (N) and/or Non-normal (NN) control states, as indicated in this attachment. Where test results are independent of control state, Normal or Non-normal control data may be used. All tests in Table A2A require test results in the Normal control state unless specifically noted otherwise in the Test Details section following the CCA designation. The NSPM will determine what tests are appropriate for airplane simulation data. When making this determination, the NSPM may require other levels of control state degradation for specific airplane tests. Where Non-normal control states are required, test data must be provided for one or more Non-normal control states, and must include the least augmented state. Where applicable, flight test data must record Normal and Non-normal states for:

(1) Pilot controller deflections or electronically generated inputs, including location of input; and

(2) Flight control surface positions unless test results are not affected by, or are independent of, surface positions.

k. Tests of handling qualities must include validation of augmentation devices. FFSs for highly augmented airplanes will be validated both in the unaugmented configuration (or failure state with the maximum permitted degradation in handling qualities) and the augmented configuration. Where various levels of handling qualities result from failure states, validation of the effect of the failure is necessary. Requirements for testing will be mutually agreed to between the sponsor and the NSPM on a case-by-case basis.

l. Some tests will not be required for airplanes using airplane hardware in the simulator flight deck (e.g., “side stick controller”). These exceptions are noted in Section 2 “Handling Qualities” in Table A2A of this attachment. However, in these cases, the sponsor must provide a statement that the airplane hardware meets the appropriate manufacturer's specifications and the sponsor must have supporting information to that fact available for NSPM review.

m. For objective test purposes, see Appendix F of this part for the definitions of “Near maximum,” “Light,” and “Medium” gross weight.

End QPS Requirements

Begin Information

n. In those cases where the objective test results authorize a “snapshot test” or a “series of snapshot tests” results in lieu of a time-history result, the sponsor or other data provider must ensure that a steady state condition exists at the instant of time captured by the “snapshot.” The steady state condition should exist from 4 seconds prior to, through 1 second following, the instant of time captured by the snap shot.

2. Handling Qualities.
For simulators requiring Static or Dynamic tests at the controls (i.e., column, wheel, rudder pedal), special test fixtures will not be required during initial or upgrade evaluations if the sponsor's QTG/MQTG shows both test fixture results and the results of an alternative approach, such as computer plots produced concurrently, that provide satisfactory agreement. Repeat of the alternative method during the initial or upgrade evaluation satisfies this test requirement. For initial and upgrade evaluations, the control dynamic characteristics must be measured at and recorded directly from the flight deck controls, and must be accomplished in takeoff, cruise, and landing flight conditions and configurations. Testing of position versus force is not applicable if forces are generated solely by use of airplane hardware in the FFS.Contact the NSPM for clarification of any issue regarding airplanes with reversible controls.

4. Control Dynamics

a. General. The characteristics of an airplane flight control system have a major effect on handling qualities. A significant consideration in pilot acceptability of an airplane is the “feel” provided through the flight controls. Considerable effort is expended on airplane feel system design so that pilots will be comfortable and will consider the airplane desirable to fly. In order for an FFS to be representative, it should “feel” like the airplane being simulated. Compliance with this requirement is determined by comparing a recording of the control feel dynamics of the FFS to actual airplane measurements in the takeoff, cruise and landing configurations.

(1) Recordings such as free response to an impulse or step function are classically used to estimate the dynamic properties of electromechanical systems. In any case, it is only possible to estimate the dynamic properties as a result of being able to estimate true inputs and responses. Therefore, it is imperative that the best possible data be collected since close matching of the FFS control loading system to the airplane system is essential. The required dynamic control tests are described in Table A2A of this attachment.

(2) For initial and upgrade evaluations, the QPS requires that control dynamics characteristics be measured and recorded directly from the flight controls (Handling Qualities—Table A2A). This procedure is usually accomplished by measuring the free response of the controls using a step or impulse input to excite the system. The procedure should be accomplished in the takeoff, cruise and landing flight conditions and configurations.

(3) For airplanes with irreversible control systems, measurements may be obtained on the ground if proper pitot-static inputs are provided to represent airspeeds typical of those encountered in flight. Likewise, it may be shown that for some airplanes, takeoff, cruise, and landing configurations have like effects. Thus, one may suffice for another. In either case, engineering validation or airplane manufacturer rationale should be submitted as justification for ground tests or for eliminating a configuration. For FFSs requiring static and dynamic tests at the controls, special test fixtures will not be required during initial and upgrade evaluations if the QTG shows both test fixture results and the results of an alternate approach (e.g., computer plots that were produced concurrently and show satisfactory agreement). Repeat of the alternate method during the initial evaluation satisfies this test requirement.

b. Control Dynamics Evaluation. The dynamic properties of control systems are often stated in terms of frequency, damping and a number of other classical measurements. In order to establish a consistent means of validating test results for FFS control loading, criteria are needed that will clearly define the measurement interpretation and the applied tolerances. Criteria are needed for underdamped, critically damped and overdamped systems. In the case of an underdamped system with very light damping, the system may be quantified in terms of frequency and damping. In critically damped or overdamped systems, the frequency and damping are not readily measured from a response time history. Therefore, the following suggested measurements may be used:

(1) For Level C and D simulators. Tests to verify that control feel dynamics represent the airplane should show that the dynamic damping cycles (free response of the controls) match those of the airplane within specified tolerances. The NSPM recognizes that several different testing methods may be used to verify the control feel dynamic response. The NSPM will consider the merits of testing methods based on reliability and consistency. One acceptable method of evaluating the response and the tolerance to be applied is described below for the underdamped and critically damped cases. A sponsor using this method to comply with the QPS requirements should perform the tests as follows:

(a) Underdamped response. Two measurements are required for the period, the time to first zero crossing (in case a rate limit is present) and the subsequent frequency of oscillation. It is necessary to measure cycles on an individual basis in case there are non-uniform periods in the response. Each period will be independently compared to the respective period of the airplane control system and, consequently, will enjoy the full tolerance specified for that period. The damping tolerance will be applied to overshoots on an individual basis. Care should be taken when applying the tolerance to small overshoots since the significance of such overshoots becomes questionable. Only those overshoots larger than 5 per cent of the total initial displacement should be considered. The residual band, labeled T(Ad) on Figure A2A is ±5 percent of the initial displacement amplitude Ad from the steady state value of the oscillation. Only oscillations outside the residual band are considered significant. When comparing FFS data to airplane data, the process should begin by overlaying or aligning the FFS and airplane steady state values and then comparing amplitudes of oscillation peaks, the time of the first zero crossing and individual periods of oscillation. The FFS should show the same number of significant overshoots to within one when compared against the airplane data. The procedure for evaluating the response is illustrated in Figure A2A.

(b) Critically damped and overdamped response. Due to the nature of critically damped and overdamped responses (no overshoots), the time to reach 90 percent of the steady state (neutral point) value should be the same as the airplane within ±10 percent. Figure A2B illustrates the procedure.

(c) Special considerations. Control systems that exhibit characteristics other than classical overdamped or underdamped responses should meet specified tolerances. In addition, special consideration should be given to ensure that significant trends are maintained.

(2) Tolerances.

(a) The following table summarizes the tolerances, T, for underdamped systems, and “n” is the sequential period of a full cycle of oscillation. See Figure A2A of this attachment for an illustration of the referenced measurements.

c. Alternative method for control dynamics evaluation.

(1) An alternative means for validating control dynamics for aircraft with hydraulically powered flight controls and artificial feel systems is by the measurement of control force and rate of movement. For each axis of pitch, roll, and yaw, the control must be forced to its maximum extreme position for the following distinct rates. These tests are conducted under normal flight and ground conditions.

(a) Static test—Slowly move the control so that a full sweep is achieved within 95 to 105 seconds. A full sweep is defined as movement of the controller from neutral to the stop, usually aft or right stop, then to the opposite stop, then to the neutral position.

(b) Slow dynamic test—Achieve a full sweep within 8-12 seconds.

(c) Fast dynamic test—Achieve a full sweep within 3-5 seconds.

Note:

Dynamic sweeps may be limited to forces not exceeding 100 lbs. (44.5 daN).

(d) Tolerances

(i) Static test; see Table A2A, FFS Objective Tests, Entries 2.a.1., 2.a.2., and 2.a.3.

d. The FAA is open to alternative means such as the one described above. The alternatives should be justified and appropriate to the application. For example, the method described here may not apply to all manufacturers' systems and certainly not to aircraft with reversible control systems.

If the FAA finds that alternative methods do not result in satisfactory performance, more Start Printed Page 26535conventionally accepted methods will have to be used.

5. Ground Effect

a. For an FFS to be used for take-off and landing (not applicable to Level A simulators in that the landing maneuver may not be credited in a Level A simulator) it should reproduce the aerodynamic changes that occur in ground effect. The parameters chosen for FFS validation should indicate these changes.

(1) A dedicated test should be provided that will validate the aerodynamic ground effect characteristics.

(2) The organization performing the flight tests may select appropriate test methods and procedures to validate ground effect. However, the flight tests should be performed with enough duration near the ground to sufficiently validate the ground-effect model.

b. The NSPM will consider the merits of testing methods based on reliability and consistency. Acceptable methods of validating ground effect are described below. If other methods are proposed, rationale should be provided to conclude that the tests performed validate the ground-effect model. A sponsor using the methods described below to comply with the QPS requirements should perform the tests as follows:

(1) Level fly-bys. The level fly-bys should be conducted at a minimum of three altitudes within the ground effect, including one at no more than 10% of the wingspan above the ground, one each at approximately 30% and 50% of the wingspan where height refers to main gear tire above the ground. In addition, one level-flight trim condition should be conducted out of ground effect (e.g., at 150% of wingspan).

(2) Shallow approach landing. The shallow approach landing should be performed at a glide slope of approximately one degree with negligible pilot activity until flare.

c. The lateral-directional characteristics are also altered by ground effect. For example, because of changes in lift, roll damping is affected. The change in roll damping will affect other dynamic modes usually evaluated for FFS validation. In fact, Dutch roll dynamics, spiral stability, and roll-rate for a given lateral control input are altered by ground effect. Steady heading sideslips will also be affected. These effects should be accounted for in the FFS modeling. Several tests such as crosswind landing, one engine inoperative landing, and engine failure on take-off serve to validate lateral-directional ground effect since portions of these tests are accomplished as the aircraft is descending through heights above the runway at which ground effect is an important factor.

6. Motion System

a. General.

(1) Pilots use continuous information signals to regulate the state of the airplane. In concert with the instruments and outside-world visual information, whole-body motion feedback is essential in assisting the pilot to control the airplane dynamics, particularly in the presence of external disturbances. The motion system should meet basic objective performance criteria, and should be subjectively tuned at the pilot's seat position to represent the linear and angular accelerations of the airplane during a prescribed minimum set of maneuvers and conditions. The response of the motion cueing system should also be repeatable.

(2) The Motion System tests in Section 3 of Table A2A are intended to qualify the FFS motion cueing system from a mechanical performance standpoint. Additionally, the list of motion effects provides a representative sample of dynamic conditions that should be present in the flight simulator. An additional list of representative, training-critical maneuvers, selected from Section 1 (Performance tests), and Section 2 (Handling Qualities tests), in Table A2A, that should be recorded during initial qualification (but without tolerance) to indicate the flight simulator motion cueing performance signature have been identified (reference Section 3.e). These tests are intended to help improve the overall standard of FFS motion cueing.

b. Motion System Checks. The intent of test 3a, Frequency Response, test 3b, Leg Balance, and test 3c, Turn-Around Check, as described in the Table of Objective Tests, is to demonstrate the performance of the motion system hardware, and to check the integrity of the motion set-up with regard to calibration and wear. These tests are independent of the motion cueing software and should be considered robotic tests.

c. Motion System Repeatability. The intent of this test is to ensure that the motion system software and motion system hardware have not degraded or changed over time. This diagnostic test should be completed during continuing qualification checks in lieu of the robotic tests. This will allow an improved ability to determine changes in the software or determine degradation in the hardware. Start Printed Page 26538The following information delineates the methodology that should be used for this test.

(1) Input: The inputs should be such that rotational accelerations, rotational rates, and linear accelerations are inserted before the transfer from airplane center of gravity to pilot reference point with a minimum amplitude of 5 deg/sec/sec, 10 deg/sec and 0.3 g, respectively, to provide adequate analysis of the output.

(2) Recommended output:

(a) Actual platform linear accelerations; the output will comprise accelerations due to both the linear and rotational motion acceleration;

(b) Motion actuators position.

d. Motion Cueing Performance Signature.

(1) Background. The intent of this test is to provide quantitative time history records of motion system response to a selected set of automated QTG maneuvers during initial qualification. This is not intended to be a comparison of the motion platform accelerations against the flight test recorded accelerations (i.e., not to be compared against airplane cueing). If there is a modification to the initially qualified motion software or motion hardware (e.g., motion washout filter, simulator payload change greater than 10%) then a new baseline may need to be established.

(2) Test Selection. The conditions identified in Section 3.e. in Table A2A are those maneuvers where motion cueing is the most discernible. They are general tests applicable to all types of airplanes and should be completed for motion cueing performance signature at any time acceptable to the NSPM prior to or during the initial qualification evaluation, and the results included in the MQTG.

(3) Priority. Motion system should be designed with the intent of placing greater importance on those maneuvers that directly influence pilot perception and control of the airplane motions. For the maneuvers identified in section 3.e. in Table A2A, the flight simulator motion cueing system should have a high tilt co-ordination gain, high rotational gain, and high correlation with respect to the airplane simulation model.

(4) Data Recording. The minimum list of parameters provided should allow for the determination of the flight simulator's motion cueing performance signature for the initial qualification evaluation. The following parameters are recommended as being acceptable to perform such a function:

(a) Flight model acceleration and rotational rate commands at the pilot reference point;

(b) Motion actuators position;

(c) Actual platform position;

(d) Actual platform acceleration at pilot reference point.

e. Motion Vibrations.

(1) Presentation of results. The characteristic motion vibrations may be used to verify that the flight simulator can reproduce the frequency content of the airplane when flown in specific conditions. The test results should be presented as a Power Spectral Density (PSD) plot with frequencies on the horizontal axis and amplitude on the vertical axis. The airplane data and flight simulator data should be presented in the same format with the same scaling. The algorithms used for generating the flight simulator data should be the same as those used for the airplane data. If they are not the same then the algorithms used for the flight simulator data should be proven to be sufficiently comparable. As a minimum, the results along the dominant axes should be presented and a rationale for not presenting the other axes should be provided.

(2) Interpretation of results. The overall trend of the PSD plot should be considered while focusing on the dominant frequencies. Less emphasis should be placed on the differences at the high frequency and low amplitude portions of the PSD plot. During the analysis, certain structural components of the flight simulator have resonant frequencies that are filtered and may not appear in the PSD plot. If filtering is required, the notch filter bandwidth should be limited to 1 Hz to ensure that the buffet feel is not adversely affected. In addition, a rationale should be provided to explain that the characteristic motion vibration is not being adversely affected by the filtering. The amplitude should match airplane data as described below. However, if the PSD plot was altered for subjective reasons, a rationale should be provided to justify the change. If the plot is on a logarithmic scale, it may be difficult to interpret the amplitude of the buffet in terms of acceleration. For example, a 1×10−3 g-rms2/Hz would describe a heavy buffet and may be seen in the deep stall regime. Alternatively, a 1×10−6 g-rms2/Hz buffet is almost not perceivable; but may represent a flap buffet at low speed. The previous two examples differ in magnitude by 1000. On a PSD plot this represents three decades (one decade is a change in order of magnitude of 10; and two decades is a change in order of magnitude of 100).

Note:

In the example, “g-rms2 is the mathematical expression for “g's root mean squared.”

7. Sound System

a. General. The total sound environment in the airplane is very complex, and changes with atmospheric conditions, airplane configuration, airspeed, altitude, and power settings. Flight deck sounds are an important component of the flight deck operational environment and provide valuable information to the flight crew. These aural cues can either assist the crew (as an indication of an abnormal situation), or hinder the crew (as a distraction or nuisance). For effective training, the flight simulator should provide flight deck sounds that are perceptible to the pilot during normal and abnormal operations, and comparable to those of the airplane. The flight simulator operator should carefully evaluate background noises in the location where the device will be installed. To demonstrate compliance with the sound requirements, the objective or validation tests in this attachment were selected to provide a representative sample of normal static conditions typically experienced by a pilot.

b. Alternate propulsion. For FFS with multiple propulsion configurations, any condition listed in Table A2A of this attachment should be presented for evaluation as part of the QTG if identified by the airplane manufacturer or other data supplier as significantly different due to a change in propulsion system (engine or propeller).

c. Data and Data Collection System.

(1) Information provided to the flight simulator manufacturer should be presented in the format suggested by the International Air Transport Association (IATA) “Flight Simulator Design and Performance Data Requirements,” as amended. This information should contain calibration and frequency response data.

(2) The system used to perform the tests listed in Table A2A should comply with the following standards:

(a) The specifications for octave, half octave, and third octave band filter sets may be found in American National Standards Institute (ANSI) S1.11-1986;

(b) Measurement microphones should be type WS2 or better, as described in International Electrotechnical Commission (IEC) 1094-4-1995.

(3) Headsets. If headsets are used during normal operation of the airplane they should also be used during the flight simulator evaluation.

(4) Playback equipment. Playback equipment and recordings of the QTG conditions should be provided during initial evaluations.

(5) Background noise.

(a) Background noise is the noise in the flight simulator that is not associated with the airplane, but is caused by the flight simulator's cooling and hydraulic systems and extraneous noise from other locations in the building. Background noise can seriously impact the correct simulation of airplane sounds and should be kept below the airplane sounds. In some cases, the sound level of the simulation can be increased to compensate for the background noise. However, this approach is limited by the specified tolerances and by the subjective acceptability of the sound environment to the evaluation pilot.

(b) The acceptability of the background noise levels is dependent upon the normal sound levels in the airplane being represented. Background noise levels that fall below the lines defined by the following points, may be acceptable:

(i) 70 dB @ 50 Hz;

(ii) 55 dB @ 1000 Hz;

(iii) 30 dB @ 16 kHz

(Note: These limits are for unweighted 1/3 octave band sound levels. Meeting these limits for background noise does not ensure an acceptable flight simulator. Airplane sounds that fall below this limit require careful review and may require lower limits on background noise.)

(6) Validation testing. Deficiencies in airplane recordings should be considered when applying the specified tolerances to ensure that the simulation is representative of the airplane. Examples of typical deficiencies are:

(a) Variation of data between tail numbers;

(b) Frequency response of microphones;

(c) Repeatability of the measurements. Start Printed Page 26539

8. Additional Information About Flight Simulator Qualification for New or Derivative Airplanes

a. Typically, an airplane manufacturer's approved final data for performance, handling qualities, systems or avionics is not available until well after a new or derivative airplane has entered service. However, flight crew training and certification often begins several months prior to the entry of the first airplane into service. Consequently, it may be necessary to use preliminary data provided by the airplane manufacturer for interim qualification of flight simulators.

b. In these cases, the NSPM may accept certain partially validated preliminary airplane and systems data, and early release (“red label”) avionics data in order to permit the necessary program schedule for training, certification, and service introduction.

c. Simulator sponsors seeking qualification based on preliminary data should consult the NSPM to make special arrangements for using preliminary data for flight simulator qualification. The sponsor should also consult the airplane and flight simulator manufacturers to develop a data plan and flight simulator qualification plan.

d. The procedure to be followed to gain NSPM acceptance of preliminary data will vary from case to case and between airplane manufacturers. Each airplane manufacturer's new airplane development and test program is designed to suit the needs of the particular project and may not contain the same events or sequence of events as another manufacturer's program, or even the same manufacturer's program for a different airplane. Therefore, there cannot be a prescribed invariable procedure for acceptance of preliminary data, but instead there should be a statement describing the final sequence of events, data sources, and validation procedures agreed by the simulator sponsor, the airplane manufacturer, the flight simulator manufacturer, and the NSPM.

Note:

A description of airplane manufacturer-provided data needed for flight simulator modeling and validation is to be found in the IATA Document “Flight Simulator Design and Performance Data Requirements,” as amended.

e. The preliminary data should be the manufacturer's best representation of the airplane, with assurance that the final data will not significantly deviate from the preliminary estimates. Data derived from these predictive or preliminary techniques should be validated against available sources including, at least, the following:

(1) Manufacturer's engineering report. The report should explain the predictive method used and illustrate past success of the method on similar projects. For example, the manufacturer could show the application of the method to an earlier airplane model or predict the characteristics of an earlier model and compare the results to final data for that model.

(2) Early flight test results. This data is often derived from airplane certification tests, and should be used to maximum advantage for early flight simulator validation. Certain critical tests that would normally be done early in the airplane certification program should be included to validate essential pilot training and certification maneuvers. These include cases where a pilot is expected to cope with an airplane failure mode or an engine failure. Flight test data that will be available early in the flight test program will depend on the airplane manufacturer's flight test program design and may not be the same in each case. The flight test program of the airplane manufacturer should include provisions for generation of very early flight test results for flight simulator validation.

f. The use of preliminary data is not indefinite. The airplane manufacturer's final data should be available within 12 months after the airplane's first entry into service or as agreed by the NSPM, the simulator sponsor, and the airplane manufacturer. When applying for interim qualification using preliminary data, the simulator sponsor and the NSPM should agree on the update program. This includes specifying that the final data update will be installed in the flight simulator within a period of 12 months following the final data release, unless special conditions exist and a different schedule is acceptable. The flight simulator performance and handling validation would then be based on data derived from flight tests or from other approved sources. Initial airplane systems data should be updated after engineering tests. Final airplane systems data should also be used for flight simulator programming and validation.

g. Flight simulator avionics should stay essentially in step with airplane avionics (hardware and software) updates. The permitted time lapse between airplane and Start Printed Page 26540flight simulator updates should be minimal. It may depend on the magnitude of the update and whether the QTG and pilot training and certification are affected. Differences in airplane and flight simulator avionics versions and the resulting effects on flight simulator qualification should be agreed between the simulator sponsor and the NSPM. Consultation with the flight simulator manufacturer is desirable throughout the qualification process.

h. The following describes an example of the design data and sources that might be used in the development of an interim qualification plan.

(1) The plan should consist of the development of a QTG based upon a mix of flight test and engineering simulation data. For data collected from specific airplane flight tests or other flights, the required design model or data changes necessary to support an acceptable Proof of Match (POM) should be generated by the airplane manufacturer.

(2) For proper validation of the two sets of data, the airplane manufacturer should compare their simulation model responses against the flight test data, when driven by the same control inputs and subjected to the same atmospheric conditions as recorded in the flight test. The model responses should result from a simulation where the following systems are run in an integrated fashion and are consistent with the design data released to the flight simulator manufacturer:

(a) Propulsion;

(b) Aerodynamics;

(c) Mass properties;

(d) Flight controls;

(e) Stability augmentation; and

(f) Brakes/landing gear.

i. A qualified test pilot should be used to assess handling qualities and performance evaluations for the qualification of flight simulators of new airplane types.

9. Engineering Simulator—Validation Data

a. When a fully validated simulation (i.e., validated with flight test results) is modified due to changes to the simulated airplane configuration, the airplane manufacturer or other acceptable data supplier must coordinate with the NSPM if they propose to supply validation data from an “audited” engineering simulator/simulation to selectively supplement flight test data. The NSPM must be provided an opportunity to audit the engineering simulation or the engineering simulator used to generate the validation data. Validation data from an audited engineering simulation may be used for changes that are incremental in nature. Manufacturers or other data suppliers must be able to demonstrate that the predicted changes in aircraft performance are based on acceptable aeronautical principles with proven success history and valid outcomes. This must include comparisons of predicted and flight test validated data.

b. Airplane manufacturers or other acceptable data suppliers seeking to use an engineering simulator for simulation validation data as an alternative to flight-test derived validation data, must contact the NSPM and provide the following:

(1) A description of the proposed aircraft changes, a description of the proposed simulation model changes, and the use of an integral configuration management process, including a description of the actual simulation model modifications that includes a step-by-step description leading from the original model(s) to the current model(s).

(2) A schedule for review by the NSPM of the proposed plan and the subsequent validation data to establish acceptability of the proposal.

(3) Validation data from an audited engineering simulator/simulation to supplement specific segments of the flight test data.

c. To be qualified to supply engineering simulator validation data, for aerodynamic, engine, flight control, or ground handling models, an airplane manufacturer or other acceptable data supplier must:

(1) Be able to verify their ability able to:

(a) Develop and implement high fidelity simulation models; and

(b) Predict the handling and performance characteristics of an airplane with sufficient accuracy to avoid additional flight test activities for those handling and performance characteristics.

(2) Have an engineering simulator that:

(a) Is a physical entity, complete with a flight deck representative of the simulated class of airplane;

(b) Has controls sufficient for manual flight;

(c) Has models that run in an integrated manner;

(d) Has fully flight-test validated simulation models as the original or baseline simulation models;

(e) Has an out-of-the-flight deck visual system;

(f) Has actual avionics boxes interchangeable with the equivalent software simulations to support validation of released software;

(g) Uses the same models as released to the training community (which are also used to produce stand-alone proof-of-match and checkout documents);

(h) Is used to support airplane development and certification; and

(i) Has been found to be a high fidelity representation of the airplane by the manufacturer's pilots (or other acceptable data supplier), certificate holders, and the NSPM.

(3) Use the engineering simulator/simulation to produce a representative set of integrated proof-of-match cases.

(4) Use a configuration control system covering hardware and software for the operating components of the engineering simulator/simulation.

(5) Demonstrate that the predicted effects of the change(s) are within the provisions of sub-paragraph ``a'' of this section, and confirm that additional flight test data are not required.

d. Additional Requirements for Validation Data

(1) When used to provide validation data, an engineering simulator must meet the simulator standards currently applicable to training simulators except for the data package.

(2) The data package used must be:

(a) Comprised of the engineering predictions derived from the airplane design, development, or certification process;

(b) Based on acceptable aeronautical principles with proven success history and valid outcomes for aerodynamics, engine operations, avionics operations, flight control applications, or ground handling;

(c) Verified with existing flight-test data; and

(d) Applicable to the configuration of a production airplane, as opposed to a flight-test airplane.

(3) Where engineering simulator data are used as part of a QTG, an essential match must exist between the training simulator and the validation data.

(4) Training flight simulator(s) using these baseline and modified simulation models must be qualified to at least internationally recognized standards, such as contained in the ICAO Document 9625, the ``Manual of Criteria for the Qualification of Flight Simulators.''

11. Validation Test Tolerances

Begin Information

a. Non-Flight-Test Tolerances

(1) If engineering simulator data or other non-flight-test data are used as an allowable form of reference validation data for the objective tests listed in Table A2A of this attachment, the data provider must supply a well-documented mathematical model and testing procedure that enables a replication of the engineering simulation results within 20% of the corresponding flight test tolerances.

b. Background

(1) The tolerances listed in Table A2A of this attachment are designed to measure the quality of the match using flight-test data as a reference.

(2) Good engineering judgment should be applied to all tolerances in any test. A test is failed when the results clearly fall outside of the prescribed tolerance(s).

(3) Engineering simulator data are acceptable because the same simulation models used to produce the reference data are also used to test the flight training simulator (i.e., the two sets of results should be ``essentially'' similar).

(4) The results from the two sources may differ for the following reasons:

(a) Hardware (avionics units and flight controls);

(b) Iteration rates;

(c) Execution order;

(d) Integration methods;

(e) Processor architecture;

(f) Digital drift, including:

(i) Interpolation methods;

(ii) Data handling differences; and

(iii) Auto-test trim tolerances.

(5) The tolerance limit between the reference data and the flight simulator results Start Printed Page 26541is generally 20% of the corresponding ``flight-test'' tolerances. However, there may be cases where the simulator models used are of higher fidelity, or the manner in which they are cascaded in the integrated testing loop have the effect of a higher fidelity, than those supplied by the data provider. Under these circumstances, it is possible that an error greater than 20% may be generated. An error greater than 20% may be acceptable if simulator sponsor can provide an adequate explanation.

(6) Guidelines are needed for the application of tolerances to engineering-simulator-generated validation data because:

(a) Flight-test data are often not available due to technical reasons;

(b) Alternative technical solutions are being advanced; and

(c) High costs.

12. Validation Data Roadmap

a. Airplane manufacturers or other data suppliers should supply a validation data roadmap (VDR) document as part of the data package. A VDR document contains guidance material from the airplane validation data supplier recommending the best possible sources of data to be used as validation data in the QTG. A VDR is of special value when requesting interim qualification, qualification of simulators for airplanes certificated prior to 1992, and qualification of alternate engine or avionics fits. A sponsor seeking to have a device qualified in accordance with the standards contained in this QPS appendix should submit a VDR to the NSPM as early as possible in the planning stages. The NSPM is the final authority to approve the data to be used as validation material for the QTG. The NSPM and the Joint Aviation Authorities' Synthetic Training Devices Advisory Board have committed to maintain a list of agreed VDRs.

b. The VDR should identify (in matrix format) sources of data for all required tests. It should also provide guidance regarding the validity of these data for a specific engine type, thrust rating configuration, and the revision levels of all avionics affecting airplane handling qualities and performance. The VDR should include rationale or explanation in cases where data or parameters are missing, engineering simulation data are to be used, flight test methods require explanation, or there is any deviation from data requirements. Additionally, the document should refer to other appropriate sources of validation data (e.g., sound and vibration data documents).

c. The Sample Validation Data Roadmap (VDR) for airplanes, shown in Table A2C, depicts a generic roadmap matrix identifying sources of validation data for an abbreviated list of tests. This document is merely a sample and does not provide actual data. A complete matrix should address all test conditions and provide actual data and data sources.

d. Two examples of rationale pages are presented in Appendix F of the IATA “Flight Simulator Design and Performance Data Requirements.” These illustrate the type of airplane and avionics configuration information and descriptive engineering rationale used to describe data anomalies or provide an acceptable basis for using alternative data for QTG validation requirements.

13. Acceptance Guidelines for Alternative Engines Data.

a. Background

(1) For a new airplane type, the majority of flight validation data are collected on the first airplane configuration with a “baseline” engine type. These data are then used to validate all flight simulators representing that airplane type.

(2) Additional flight test validation data may be needed for flight simulators representing an airplane with engines of a different type than the baseline, or for engines with thrust rating that is different from previously validated configurations.

(3) When a flight simulator with alternate engines is to be qualified, the QTG should contain tests against flight test validation data for selected cases where engine differences are expected to be significant.

b. Approval Guidelines For Validating Alternate Engine Applications

(1) The following guidelines apply to flight simulators representing airplanes with alternate engine applications or with more than one engine type or thrust rating.

(2) Validation tests can be segmented into two groups, those that are dependent on engine type or thrust rating and those that are not.

(3) For tests that are independent of engine type or thrust rating, the QTG can be based on validation data from any engine application. Tests in this category should be designated as independent of engine type or thrust rating.

(4) For tests that are affected by engine type, the QTG should contain selected engine-specific flight test data sufficient to validate that particular airplane-engine configuration. These effects may be due to engine dynamic characteristics, thrust levels or engine-related airplane configuration changes. This category is primarily characterized by variations between different engine manufacturers' products, but also includes differences due to significant engine design changes from a previously flight-validated configuration within a single engine type. See Table A2D, Alternate Engine Validation Flight Tests in this section for a list of acceptable tests.

(5) Alternate engine validation data should be based on flight test data, except as noted in sub-paragraphs 13.c.(1) and (2), or where other data are specifically allowed (e.g., engineering simulator/simulation data). If certification of the flight characteristics of the airplane with a new thrust rating (regardless of percentage change) does require certification flight testing with a comprehensive stability and control flight instrumentation package, then the conditions described in Table A2D in this section should be obtained from flight testing and presented in the QTG. Flight test data, other than throttle calibration data, are not required if the new thrust rating is certified on the airplane without need for a comprehensive stability and control flight instrumentation package.

(6) As a supplement to the engine-specific flight tests listed in Table A2D and baseline engine-independent tests, additional engine-specific engineering validation data should be provided in the QTG, as appropriate, to facilitate running the entire QTG with the alternate engine configuration. The sponsor and the NSPM should agree in advance on the specific validation tests to be supported by engineering simulation data.

(7) A matrix or VDR should be provided with the QTG indicating the appropriate validation data source for each test.

(8) The flight test conditions in Table A2D are appropriate and should be sufficient to validate implementation of alternate engines in a flight simulator.

End Information

Begin QPS Requirement

c. Test Requirements

(1) The QTG must contain selected engine-specific flight test data sufficient to validate the alternative thrust level when:

(a) the engine type is the same, but the thrust rating exceeds that of a previously flight-test validated configuration by five percent (5%) or more; or

(b) the engine type is the same, but the thrust rating is less than the lowest previously flight-test validated rating by fifteen percent (15%) or more. See Table A2D for a list of acceptable tests.

(2) Flight test data is not required if the thrust increase is greater than 5%, but flight tests have confirmed that the thrust increase does not change the airplane's flight characteristics.

(3) Throttle calibration data (i.e., commanded power setting parameter versus throttle position) must be provided to validate all alternate engine types and engine thrust ratings that are higher or lower than a previously validated engine. Data from a test airplane or engineering test bench with the correct engine controller (both hardware and software) are required.

14. Acceptance Guidelines for Alternative Avionics (Flight-Related Computers and Controllers)

a. Background

(1) For a new airplane type, the majority of flight validation data are collected on the first airplane configuration with a ``baseline'' flight-related avionics ship-set; (see subparagraph b.(2) of this section). These data are then used to validate all flight simulators representing that airplane type.

(2) Additional validation data may be required for flight simulators representing an airplane with avionics of a different hardware design than the baseline, or a different software revision than previously validated configurations.

(3) When a flight simulator with additional or alternate avionics configurations is to be qualified, the QTG should contain tests against validation data for selected cases where avionics differences are expected to be significant.

b. Approval Guidelines for Validating Alternate Avionics

(1) The following guidelines apply to flight simulators representing airplanes with a revised avionics configuration, or more than one avionics configuration.

(2) The baseline validation data should be based on flight test data, except where other data are specifically allowed (e.g., engineering flight simulator data).

(3) The airplane avionics can be segmented into two groups, systems or components whose functional behavior contributes to the aircraft response presented in the QTG results, and systems that do not. The following avionics are examples of contributory systems for which hardware design changes or software revisions may lead to significant differences in the aircraft response relative to the baseline avionics configuration: Flight control computers and controllers for engines, autopilot, braking system, nosewheel steering system, and high lift system. Related avionics such as stall warning and augmentation systems should also be considered.

(4) The acceptability of validation data used in the QTG for an alternative avionics fit should be determined as follows:

(a) For changes to an avionics system or component that do not affect QTG validation test response, the QTG test can be based on validation data from the previously validated avionics configuration.

(b) For an avionics change to a contributory system, where a specific test is not affected by the change (e.g., the avionics change is a Built In Test Equipment (BITE) update or a modification in a different flight phase), the QTG test can be based on validation data from the previously-validated avionics configuration. The QTG should include authoritative justification (e.g., from the airplane manufacturer or system supplier) that this avionics change does not affect the test.

(c) For an avionics change to a contributory system, the QTG may be based on validation data from the previously-validated avionics configuration if no new functionality is added and the impact of the avionics change on the airplane response is small and based on acceptable aeronautical principles with proven success history and valid outcomes. This should be supplemented with avionics-specific validation data from the airplane manufacturer's engineering simulation, generated with the revised avionics configuration. The QTG should also include an explanation of the nature of the change and its effect on the airplane response.

(d) For an avionics change to a contributory system that significantly affects some tests in the QTG or where new functionality is added, the QTG should be based on validation data from the previously validated avionics configuration and supplemental avionics-specific flight test data sufficient to validate the alternate avionics revision. Additional flight test validation data may not be needed if the avionics changes were certified without the need for testing with a comprehensive flight instrumentation package. The airplane manufacturer should coordinate flight simulator data requirements, in advance with the NSPM.

(5) A matrix or ``roadmap'' should be provided with the QTG indicating the appropriate validation data source for each test. The roadmap should include identification of the revision state of those contributory avionics systems that could affect specific test responses if changed.

15. Transport Delay Testing

a. This paragraph explains how to determine the introduced transport delay through the flight simulator system so that it does not exceed a specific time delay. The transport delay should be measured from control inputs through the interface, through each of the host computer modules and back through the interface to motion, flight instrument, and visual systems. The transport delay should not exceed the maximum allowable interval.

b. Four specific examples of transport delay are:

(1) Simulation of classic non-computer controlled aircraft;

(2) Simulation of computer controlled aircraft using real airplane black boxes;

(3) Simulation of computer controlled aircraft using software emulation of airplane boxes;

(4) Simulation using software avionics or re-hosted instruments.

c. Figure A2C illustrates the total transport delay for a non-computer-controlled airplane or the classic transport delay test. Since there are no airplane-induced delays for this case, the total transport delay is equivalent to the introduced delay.

d. Figure A2D illustrates the transport delay testing method using the real airplane controller system.

e. To obtain the induced transport delay for the motion, instrument and visual signal, the delay induced by the airplane controller should be subtracted from the total transport delay. This difference represents the introduced delay and should not exceed the standards prescribed in Table A1A.

f. Introduced transport delay is measured from the flight deck control input to the reaction of the instruments and motion and visual systems (See Figure A2C).

g. The control input may also be introduced after the airplane controller system and the introduced transport delay measured directly from the control input to the reaction of the instruments, and simulator motion and visual systems (See Figure A2D).

h. Figure A2E illustrates the transport delay testing method used on a flight simulator that uses a software emulated airplane controller system.

i. It is not possible to measure the introduced transport delay using the simulated airplane controller system architecture for the pitch, roll and yaw axes. Therefore, the signal should be measured directly from the pilot controller. The flight simulator manufacturer should measure the total transport delay and subtract the inherent delay of the actual airplane components because the real airplane controller system has an inherent delay provided by the airplane manufacturer. The flight simulator manufacturer should ensure that the introduced delay does not exceed the standards prescribed in Table A1A.

j. Special measurements for instrument signals for flight simulators using a real airplane instrument display system instead of a simulated or re-hosted display. For flight instrument systems, the total transport delay should be measured and the inherent delay of the actual airplane components subtracted to ensure that the introduced delay does not exceed the standards prescribed in Table A1A.

(1) Figure A2FA illustrates the transport delay procedure without airplane display simulation. The introduced delay consists of the delay between the control movement and the instrument change on the data bus.

(2) Figure A2FB illustrates the modified testing method required to measure introduced delay due to software avionics or re-hosted instruments. The total simulated instrument transport delay is measured and the airplane delay should be subtracted from this total. This difference represents the introduced delay and should not exceed the standards prescribed in Table A1A. The inherent delay of the airplane between the data bus and the displays is indicated in figure A2FA. The display manufacturer should provide this delay time.

k. Recorded signals. The signals recorded to conduct the transport delay calculations should be explained on a schematic block diagram. The flight simulator manufacturer should also provide an explanation of why each signal was selected and how they relate to the above descriptions.

l. Interpretation of results. Flight simulator results vary over time from test to test due to “sampling uncertainty.” All flight simulators run at a specific rate where all modules are executed sequentially in the host computer. The flight controls input can occur at any time in the iteration, but these data will not be processed before the start of the new iteration. For example, a flight simulator running at 60 Hz may have a difference of as much as 16.67 msec between Start Printed Page 26545test results. This does not mean that the test has failed. Instead, the difference is attributed to variations in input processing. In some conditions, the host simulator and the visual system do not run at the same iteration rate, so the output of the host computer to the visual system will not always be synchronized.

m. The transport delay test should account for both daylight and night modes of operation of the visual system. In both cases, the tolerances prescribed in Table A1A must be met and the motion response should occur before the end of the first video scan containing new information.

16. Continuing Qualification Evaluations—Validation Test Data Presentation

a. Background

(1) The MQTG is created during the initial evaluation of a flight simulator. This is the master document, as amended, to which flight simulator continuing qualification evaluation test results are compared.

(2) The currently accepted method of presenting continuing qualification evaluation test results is to provide flight simulator results over-plotted with reference data. Test results are carefully reviewed to determine if the test is within the specified tolerances. This can be a time consuming process, particularly when reference data exhibits rapid variations or an apparent anomaly requiring engineering judgment in the application of the tolerances. In these cases, the solution is to compare the results to the MQTG. The continuing qualification results are compared to the results in the MQTG for acceptance. The flight simulator operator and the NSPM should look for any change in the flight simulator performance since initial qualification.

b. Continuing Qualification Evaluation Test Results Presentation

(1) Flight simulator operators are encouraged to over-plot continuing qualification validation test results with MQTG flight simulator results recorded during the initial evaluation and as amended. Any change in a validation test will be readily apparent. In addition to plotting continuing qualification validation test and MQTG results, operators may elect to plot reference data as well.

(2) There are no suggested tolerances between flight simulator continuing qualification and MQTG validation test results. Investigation of any discrepancy between the MQTG and continuing qualification flight simulator performance is left to the discretion of the flight simulator operator and the NSPM.

(3) Differences between the two sets of results, other than variations attributable to repeatability issues that cannot be explained, should be investigated.

(4) The flight simulator should retain the ability to over-plot both automatic and manual validation test results with reference data.

17. Alternative Data Sources, Procedures, and Instrumentation: Level A and Level B Simulators Only

a. Sponsors are not required to use the alternative data sources, procedures, and instrumentation. However, a sponsor may choose to use one or more of the alternative sources, procedures, and instrumentation described in Table A2E.

b. It has become standard practice for experienced simulator manufacturers to use modeling techniques to establish data bases for new simulator configurations while awaiting the availability of actual flight test data. The data generated from the aerodynamic modeling techniques is then compared to the flight test data when it becomes available. The results of such comparisons have become increasingly consistent, indicating that these techniques, applied with the appropriate experience, are dependable and accurate for the development of aerodynamic models for use in Level A and Level B simulators.

c. Based on this history of successful comparisons, the NSPM has concluded that those who are experienced in the development of aerodynamic models may use modeling techniques to alter the method for acquiring flight test data for Level A or Level B simulators.

d. The information in Table A2E (Alternative Data Sources, Procedures, and Instrumentation) is presented to describe an acceptable alternative to data sources for simulator modeling and validation and an acceptable alternative to the procedures and instrumentation traditionally used to gather such modeling and validation data.

(1) Alternative data sources that may be used for part or all of a data requirement are the Airplane Maintenance Manual, the Airplane Flight Manual (AFM), Airplane Design Data, the Type Inspection Report (TIR), Certification Data or acceptable supplemental flight test data.

(2) The sponsor should coordinate with the NSPM prior to using alternative data sources in a flight test or data gathering effort.

e. The NSPM position regarding the use of these alternative data sources, procedures, and instrumentation is based on the following presumptions:

(1) Data gathered through the alternative means does not require angle of attack (AOA) measurements or control surface position measurements for any flight test. However, AOA can be sufficiently derived if the flight test program ensures the collection of acceptable level, unaccelerated, trimmed flight data. All of the simulator time history tests that begin in level, unaccelerated, and trimmed flight, including the three basic trim tests and “fly-by” trims, can be a successful validation of angle of attack by comparison with flight test pitch angle. (Note: Due to the criticality of angle of attack in the development of the ground effects model, particularly critical for normal landings and landings involving cross-control input applicable to Level B simulators, stable “fly-by” trim data will be the acceptable norm for normal and cross-control input landing objective data for these applications.)

(2) The use of a rigorously defined and fully mature simulation controls system model that includes accurate gearing and cable stretch characteristics (where applicable), determined from actual aircraft measurements. Such a model does not require control surface position measurements in the flight test objective data in these limited applications.

f. The sponsor is urged to contact the NSPM for clarification of any issue regarding airplanes with reversible control systems. Table A2E is not applicable to Computer Controlled Aircraft FFSs.

g. Utilization of these alternate data sources, procedures, and instrumentation (Table A2E) does not relieve the sponsor from compliance with the balance of the information contained in this document relative to Level A or Level B FFSs.

h. The term “inertial measurement system” is used in the following table to include the use of a functional global positioning system (GPS).

i. Synchronized video for the use of alternative data sources, procedures, and instrumentation should have:

(1) Sufficient resolution to allow magnification of the display to make appropriate measurement and comparisons; and

(2) Sufficient size and incremental marking to allow similar measurement and comparison. The detail provided by the video should provide sufficient clarity and accuracy to measure the necessary parameter(s) to at least 1/2 of the tolerance authorized for the specific test being conducted and allow an integration of the parameter(s) in question to obtain a rate of change.

Attachment 3 to Appendix A to Part 60—Simulator Subjective Evaluation

Begin QPS Requirements

1. Requirements

a. Except for special use airport models, described as Class III, all airport models required by this part must be representations of real-world, operational airports or representations of fictional airports and must meet the requirements set out in Tables A3B or A3C of this attachment, as appropriate.

b. If fictional airports are used, the sponsor must ensure that navigational aids and all appropriate maps, charts, and other navigational reference material for the fictional airports (and surrounding areas as necessary) are compatible, complete, and accurate with respect to the visual presentation of the airport model of this fictional airport. An SOC must be submitted that addresses navigation aid installation and performance and other criteria (including obstruction clearance protection) for all instrument approaches to the fictional airports that are available in the simulator. The SOC must reference and account for information in the terminal instrument procedures manual and the construction and availability of the required maps, charts, and other navigational material. This material must be clearly marked “for training purposes only.”

c. When the simulator is being used by an instructor or evaluator for purposes of training, checking, or testing under this chapter, only airport models classified as Class I, Class II, or Class III may be used by the instructor or evaluator. Detailed descriptions/definitions of these classifications are found in Appendix F of this part.

d. When a person sponsors an FFS maintained by a person other than a U.S. certificate holder, the sponsor is accountable for that FFS originally meeting, and Start Printed Page 26553continuing to meet, the criteria under which it was originally qualified and the appropriate Part 60 criteria, including the airport models that may be used by instructors or evaluators for purposes of training, checking, or testing under this chapter.

e. Neither Class II nor Class III airport visual models are required to appear on the SOQ, and the method used for keeping instructors and evaluators apprised of the airport models that meet Class II or Class III requirements on any given simulator is at the option of the sponsor, but the method used must be available for review by the TPAA.

f. When an airport model represents a real world airport and a permanent change is made to that real world airport (e.g., a new runway, an extended taxiway, a new lighting system, a runway closure) without a written extension grant from the NSPM (described in paragraph 1.g. of this section), an update to that airport model must be made in accordance with the following time limits:

(1) For a new airport runway, a runway extension, a new airport taxiway, a taxiway extension, or a runway/taxiway closure—within 90 days of the opening for use of the new airport runway, runway extension, new airport taxiway, or taxiway extension; or within 90 days of the closure of the runway or taxiway.

(2) For a new or modified approach light system—within 45 days of the activation of the new or modified approach light system.

(3) For other facility or structural changes on the airport (e.g., new terminal, relocation of Air Traffic Control Tower)—within 180 days of the opening of the new or changed facility or structure.

g. If a sponsor desires an extension to the time limit for an update to a visual scene or airport model or has an objection to what must be updated in the specific airport model requirement, the sponsor must provide a written extension request to the NSPM stating the reason for the update delay and a proposed completion date, or explain why the update is not necessary (i.e., why the identified airport change will not have an impact on flight training, testing, or checking). A copy of this request or objection must also be sent to the POI/TCPM. The NSPM will send the official response to the sponsor and a copy to the POI/TCPM. If there is an objection, after consultation with the appropriate POI/TCPM regarding the training, testing, or checking impact, the NSPM will send the official response to the sponsor and a copy to the POI/TCPM.

2. Discussion

a. The subjective tests provide a basis for evaluating the capability of the simulator to perform over a typical utilization period; determining that the simulator accurately simulates each required maneuver, procedure, or task; and verifying correct operation of the simulator controls, instruments, and systems. The items listed in the following Tables are for simulator evaluation purposes only. They may not be used to limit or exceed the authorizations for use of a given level of simulator, as described on the SOQ, or as approved by the TPAA.

b. The tests in Table A3A, Operations Tasks, in this attachment, address pilot functions, including maneuvers and procedures (called flight tasks), and are divided by flight phases. The performance of these tasks by the NSPM includes an operational examination of the visual system and special effects. There are flight tasks included to address some features of advanced technology airplanes and innovative training programs. For example, “high angle-of-attack maneuvering” is included to provide a required alternative to “approach to stalls” for airplanes employing flight envelope protection functions.

c. The tests in Table A3A, Operations Tasks, and Table A3G, Instructor Operating Station of this attachment, address the overall function and control of the simulator including the various simulated environmental conditions; simulated airplane system operations (normal, abnormal, and emergency); visual system displays; and special effects necessary to meet flight crew training, evaluation, or flight experience requirements.

d. All simulated airplane systems functions will be assessed for normal and, where appropriate, alternate operations. Normal, abnormal, and emergency operations associated with a flight phase will be assessed during the evaluation of flight tasks or events within that flight phase. Simulated airplane systems are listed separately under “Any Flight Phase” to ensure appropriate attention to systems checks. Operational navigation systems (including inertial navigation systems, global positioning systems, or other long-range systems) and the associated electronic display systems will be evaluated if installed. The NSP pilot will include in his report to the TPAA, the effect of the system operation and any system limitation.

e. Simulators demonstrating a satisfactory circling approach will be qualified for the circling approach maneuver and may be approved for such use by the TPAA in the sponsor's FAA-approved flight training program. To be considered satisfactory, the circling approach will be flown at maximum gross weight for landing, with minimum visibility for the airplane approach category, and must allow proper alignment with a landing runway at least 90° different from the instrument approach course while allowing the pilot to keep an identifiable portion of the airport in sight throughout the maneuver (reference—14 CFR 91.175(e)).

f. At the request of the TPAA, the NSPM may assess a device to determine if it is capable of simulating certain training activities in a sponsor's training program, such as a portion of a Line Oriented Flight Training (LOFT) scenario. Unless directly related to a requirement for the qualification level, the results of such an evaluation would not affect the qualification level of the simulator. However, if the NSPM determines that the simulator does not accurately simulate that training activity, the simulator would not be approved for that training activity.

g. The FAA intends to allow the use of Class III airport models when the sponsor provides the TPAA (or other regulatory authority) an appropriate analysis of the skills, knowledge, and abilities (SKAs) necessary for competent performance of the tasks in which this particular media element is used. The analysis should describe the ability of the FFS/visual media to provide an adequate environment in which the required SKAs are satisfactorily performed and learned. The analysis should also include the specific media element, such as the airport model. Additional sources of information on the conduct of task and capability analysis may be found on the FAA's Advanced Qualification Program (AQP) Web site at: http://www.faa.gov/​education_​research/​training/​aqp/​.

h. The TPAA may accept Class III airport models without individual observation provided the sponsor provides the TPAA with an acceptable description of the process for determining the acceptability of a specific airport model, outlines the conditions under which such an airport model may be used, and adequately describes what restrictions will be applied to each resulting airport or landing area model. Examples of situations that may warrant Class_III model designation by the TPAA include the following:

(a) Training, testing, or checking on very low visibility operations, including SMGCS operations.

(b) Instrument operations training (including instrument takeoff, departure, arrival, approach, and missed approach training, testing, or checking) using—

(i) A specific model that has been geographically “moved” to a different location and aligned with an instrument procedure for another airport.

(ii) A model that does not match changes made at the real-world airport (or landing area for helicopters) being modeled.

(iii) A model generated with an “off-board” or an “on-board” model development tool (by providing proper latitude/longitude reference; correct runway or landing area orientation, length, width, marking, and lighting information; and appropriate adjacent taxiway location) to generate a facsimile of a real world airport or landing area.

i. Previously qualified simulators with certain early generation Computer Generated Image (CGI) visual systems, are limited by the capability of the Image Generator or the display system used. These systems are:

(1) Early CGI visual systems that are excepted from the requirement of including runway numbers as a part of the specific runway marking requirements are:

(a) Link NVS and DNVS.

(b) Novoview 2500 and 6000.

(c) FlightSafety VITAL series up to, and including, VITAL III, but not beyond.

(d) Redifusion SP1, SP1T, and SP2.

(2) Early CGI visual systems are excepted from the requirement of including runway numbers unless the runways are used for LOFT training sessions. These LOFT airport models require runway numbers but only for the specific runway end (one direction) used in the LOFT session. The systems required to display runway numbers only for LOFT scenes are: Start Printed Page 26554

(a) FlightSafety VITAL IV.

10.An example of being able to “combine two airport models to achieve two “in-use” runways: One runway designated as the “in use” runway in the first model of the airport, and the second runway designated as the “in use” runway in the second model of the same airport. For example, the clearance is for the ILS approach to Runway 27, Circle to Land on Runway 18 right. Two airport visual models might be used: the first with Runway 27 designated as the “in use” runway for the approach to runway 27, and the second with Runway 18 Right designated as the “in use” runway. When the pilot breaks off the ILS approach to runway 27, the instructor may change to the second airport visual model in which runway 18 Right is designated as the “in use” runway, and the pilot would make a visual approach and landing. This process is acceptable to the FAA as long as the temporary interruption due to the visual model change is not distracting to the pilot, does not cause changes in navigational radio frequencies, and does not cause undue instructor/evaluator time
11.Sponsors are not required to provide every detail of a runway, but the detail that is provided should be correct within the capabilities of the system

Entry no.Motion system effectsSimulator levelNotes
ABCD
This table specifies motion effects that are required to indicate when a flight crewmember must be able to recognize an event or situation. Where applicable, flight simulator pitch, side loading and directional control characteristics must be representative of the airplane.
1.Runway rumble, oleo deflection, ground speed, uneven runway, runway and taxiway centerline light characteristics: Procedure: After the airplane has been pre-set to the takeoff position and then released, taxi at various speeds with a smooth runway and note the general characteristics of the simulated runway rumble effects of oleo deflections. Repeat the maneuver with a runway roughness of 50%, then with maximum roughness. Note the associated motion vibrations affected by ground speed and runway roughnessXXXXDifferent gross weights can also be selected, which may also affect the associated vibrations depending on airplane type. The associated motion effects for the above tests should also include an assessment of the effects of rolling over centerline lights, surface discontinuities of uneven runways, and various taxiway characteristics.
2.Buffets on the ground due to spoiler/speedbrake extension and reverse thrust: Procedure: Perform a normal landing and use ground spoilers and reverse thrust—either individually or in combination—to decelerate the simulated airplane. Do not use wheel braking so that only the buffet due to the ground spoilers and thrust reversers is feltXXXX
Start Printed Page 26566
3.Bumps associated with the landing gear: Procedure: Perform a normal take-off paying special attention to the bumps that could be perceptible due to maximum oleo extension after lift-off. When the landing gear is extended or retracted, motion bumps can be felt when the gear locks into positionXXXX
4.Buffet during extension and retraction of landing gear: Procedure: Operate the landing gear. Check that the motion cues of the buffet experienced represent the actual airplaneXXXX
5.Buffet in the air due to flap and spoiler/speedbrake extension and approach to stall buffet: Procedure: Perform an approach and extend the flaps and slats with airspeeds deliberately in excess of the normal approach speeds. In cruise configuration, verify the buffets associated with the spoiler/speedbrake extension. The above effects can also be verified with different combinations of spoiler/speedbrake, flap, and landing gear settings to assess the interaction effectsXXXX
6.Approach to stall buffet: Procedure: Conduct an approach-to-stall with engines at idle and a deceleration of 1 knot/second. Check that the motion cues of the buffet, including the level of buffet increase with decreasing speed, are representative of the actual airplaneXXXX
7.Touchdown cues for main and nose gear: Procedure: Conduct several normal approaches with various rates of descent. Check that the motion cues for the touchdown bumps for each descent rate are representative of the actual airplaneXXXX
8.Nosewheel scuffing: Procedure: Taxi at various ground speeds and manipulate the nosewheel steering to cause yaw rates to develop that cause the nosewheel to vibrate against the ground (“scuffing”). Evaluate the speed/nosewheel combination needed to produce scuffing and check that the resultant vibrations are representative of the actual airplaneXXXX
9.Thrust effect with brakes set: Procedure: Set the brakes on at the take-off point and increase the engine power until buffet is experienced. Evaluate its characteristics. Confirm that the buffet increases appropriately with increasing engine thrustXXXXThis effect is most discernible with wing-mounted engines.
10.Mach and maneuver buffet: Procedure: With the simulated airplane trimmed in 1 g flight while at high altitude, increase the engine power so that the Mach number exceeds the documented value at which Mach buffet is experienced. Check that the buffet begins at the same Mach number as it does in the airplane (for the same configuration) and that buffet levels are representative of the actual airplane. For certain airplanes, maneuver buffet can also be verified for the same effects. Maneuver buffet can occur during turning flight at conditions greater than 1 g, particularly at higher altitudesXXX
Start Printed Page 26567
11.Tire failure dynamics: Procedure: Simulate a single tire failure and a multiple tire failureXXThe pilot may notice some yawing with a multiple tire failure selected on the same side. This should require the use of the rudder to maintain control of the airplane. Dependent on airplane type, a single tire failure may not be noticed by the pilot and should not have any special motion effect. Sound or vibration may be associated with the actual tire losing pressure.
12.Engine malfunction and engine damage: Procedure: The characteristics of an engine malfunction as stipulated in the malfunction definition document for the particular flight simulator must describe the special motion effects felt by the pilot. Note the associated engine instruments varying according to the nature of the malfunction and note the replication of the effects of the airframe vibrationXXX
13.Tail strikes and engine pod strikes: Procedure: Tail-strikes can be checked by over-rotation of the airplane at a speed below Vr while performing a takeoff. The effects can also be verified during a landing Excessive banking of the airplane during its take-off/landing roll can cause a pod strikeXXXThe motion effect should be felt as a noticeable bump. If the tail strike affects the airplane angular rates, the cueing provided by the motion system should have an associated effect.

1.Braking Dynamics:
Representations of the dynamics of brake failure (flight simulator pitch, side-loading, and directional control characteristics representative of the airplane), including antiskid and decreased brake efficiency due to high brake temperatures (based on airplane related data), sufficient to enable pilot identification of the problem and implementation of appropriate proceduresXX
2.Effects of Airframe and Engine Icing:XX
Required only for those airplanes authorized for operations in known icing conditions
Start Printed Page 26568
Procedure: With the simulator airborne, in a clean configuration, nominal altitude and cruise airspeed, autopilot on and auto-throttles off, engine and airfoil anti-ice/de-ice systems deactivated; activate icing conditions at a rate that allows monitoring of simulator and systems response. Icing recognition will include an increase in gross weight, airspeed decay, change in simulator pitch attitude, change in engine performance indications (other than due to airspeed changes), and change in data from pitot/static system. Activate heating, anti-ice, or de-ice systems independently. Recognition will include proper effects of these systems, eventually returning the simulated airplane to normal flight

1. Introduction

a. The following is an example test schedule for an Initial/Upgrade evaluation that covers the majority of the requirements set out in the Functions and Subjective test requirements. It is not intended that the schedule be followed line by line, rather, the example should be used as a guide for preparing a schedule that is tailored to the airplane, sponsor, and training task.

b. Functions and subjective tests should be planned. This information has been organized as a reference document with the considerations, methods, and evaluation notes for each individual aspect of the simulator task presented as an individual item. In this way the evaluator can design his or her own test plan, using the appropriate sections to provide guidance on method and evaluation criteria. Two aspects should be present in any test plan structure:

(1) An evaluation of the simulator to determine that it replicates the aircraft and performs reliably for an uninterrupted period equivalent to the length of a typical training session.

(2) The simulator should be capable of operating reliably after the use of training device functions such as repositions or malfunctions.

c. A detailed understanding of the training task will naturally lead to a list of objectives that the simulator should meet. This list will form the basis of the test plan. Additionally, once the test plan has been formulated, the initial conditions and the evaluation criteria should be established. The evaluator should consider all factors that may have an influence on the characteristics observed during particular training tasks in order to make the test plan successful.
