Federal Aviation Administration (FAA), DOT.


Notice of proposed policy and request for comment.


As, new technology facilitates the introduction of area navigation (RNAV) instrument approach procedures over the past decade, the number of procedures available in the National Airspace System has nearly doubled. The complexity and cost to the Federal Aviation Administration (FAA) of maintaining the existing ground based navigational infrastructure while expanding the new RNAV capability is not sustainable. The FAA is considering the cancellation of certain Non-directional Beacon (NDB) and Very High Frequency (VHF) Omnidirectional Radio Range (VOR) instrument approach procedures (IAP) at airports that have multiple instrument approach procedures. The FAA proposes specific criteria to guide the identification and selection of appropriate NDB and VOR instrument approach procedures that can be considered for cancellation. The VOR IAPs associated with this cancellation initiative would be selected from the criteria outlined below. This Notice is not a part of the FAA's VOR minimum operating network (MON) initiative.

Title 49 of the United States Code, section 40103, vests the Administrator with broad authority to regulate the safe and efficient use of the navigable airspace. The Administrator is authorized to issue rules and regulations to govern the flight, navigation, protection, and identification of aircraft for the protection of persons and property on the ground, and for the efficient use of the navigable airspace (49 U.S.C. 40103(b)). The Administrator also is authorized under § 44701(a)(5) to promote safe flight of civil aircraft in air commerce by prescribing regulations and minimum standards for other practices, methods, and procedures necessary for safety in air commerce and national security.


The FAA is continuing to expand the availability and capability of area navigation (RNAV) to improve safety and efficiency within the National Airspace System (NAS). A major enhancement is the introduction of Wide Area Augmentation System (WAAS) capable RNAV instrument approach procedures that provide for near-precision vertical guidance.

As a result of new RNAV instrument approach procedures, the number of instrument approach procedures available to the public has nearly doubled over the past decade and will continue to grow with the public's demand for new WAAS procedures. The complexity and cost of maintaining existing ground-based navigational infrastructure while expanding new RNAV capability is exceeding the FAA's current staffing and budget allocations and projections over the next five years. To meet the public's demand for WAAS capable RNAV procedures, the FAA must manage the growth in the number of instrument approach procedures and finds that certain redundant ground-based procedures can be eliminated without affecting safety or access to airports.

To help identify viable strategies for cancellation of ground-based procedures, the FAA awarded a grant to the Flight Safety Foundation. In conducting its research, the Flight Safety Foundation held meetings with FAA and Department of Defense (DOD) personnel and key industry interest groups. Outreach conducted by the Foundation identified that most NDB procedures are no longer desired, except in support of certain DOD operations and flight schools. The Flight Safety Foundation also found user support for cancelling some VOR procedures when multiple IAPs are available. Results of the Flight Safety Foundation study were published in the report titled “A Recommended Process: Safely Reducing Redundant or Underutilized Instrument Approach Procedures.” The report is available for review at:​air_​traffic/​flight_​info/​aeronav/​procedures/​reports/​media/​FAA_​Grant_​Flight_​Safety_​Foundation_​Inc-2010G023.pdf.

By this notice, the FAA seeks comments on proposed criteria that would facilitate the FAA's determination of which procedures can be considered for cancellation. After reviewing the comments submitted to this notice, the FAA will use the criteria for selection of potential NDB and VOR procedures for cancellation. Once the criteria are established and the FAA Start Printed Page 47048considers IAPs for cancellation, the FAA will publish a list of potential IAPs in the Federal Register for notice and comment. Submitted comments will be reviewed and addressed in the final list of subject IAPs published in the Federal Register. The criteria proposed in this notice does not affect any NAS navigational back-up plans and is not a part of the FAA's VOR minimum operating network (MON) initiative.

Proposed Policy

The NDB and VOR IAPs recommended for cancellation would be selected at airports using the following criteria. It must be noted that all airports that have existing RNAV and ground-based IAPs would maintain at least one RNAV and one ground-based IAP.

Airports that would be considered for NDB or VOR IAP cancellation:

— All airports with an NDB IAP.

—All airports with a VOR/DME RNAV IAP, unless it is the only IAP at the airport.

—All airports with two or more ground-based IAPs and an RNAV IAP.

—All airports with multiple, redundant ground-based IAPs (e.g., three VOR procedures).

Additional consideration would be given to the following factors in determining the list of potential candidates for cancellation:

—Prevailing wind runways.

—Prevailing runway alignment during adverse weather operations.

—If an airport has a published ILS IAP and additional ground-based IAPs, cancel the procedure to the same runway as the ILS.

—For airports with multiple VOR and NDB IAP's, retain the IAP with the lowest minimums (if minimums are within 20 feet of each other retain the procedure that allows optimum use by all customers (i.e. VOR and VOR/DME retain VOR because there are no equipage limitations).

Airports that would not be considered for NDB or VOR IAP cancellations:

—Airport with only RNAV/RNPs IAPs published.

—Airport with only one ground-based procedure.

—Airports will not be considered if cancellation would result in removing all IAPs from the airport.

Lastly, the FAA is not considering the following types of procedures for cancellation:

PBN Procedures (RNAV or RNP).

ILS procedures.

Localizer procedures.

TACAN procedures.

Standard Instrument Arrivals (STARs).

Standard Instrument Departures (SIDs).

To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments or, if comments are filed electronically, commenters should submit only one time.

The FAA will file in the docket all comments it receives. Before acting on this proposal, the FAA will consider all comments it receives on or before the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The agency may change this proposal in light of the comments it receives.

Proprietary or Confidential Business Information: Commenters should not file proprietary or confidential business information in the docket.
