Federal Aviation Administration (FAA), DOT.


Notice of proposed rulemaking (NPRM).


This action proposes to modify low altitude area navigation (RNAV) route T-288 by extending the route westward from the Rapid City, SD, VORTAC to the Gillette, WY, VOR/DME. The proposed extension would enhance efficiency and safety of the National Airspace System (NAS) by supplementing the existing VOR Federal airway structure in that area.


Comments must be received on or before January 20, 2012.

The Proposal

The FAA is proposing an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to modify RNAV route T-288 by adding a new segment between the Rapid City, SD VORTAC and the Gillette, WY VOR/DME. The modification would enhance the efficiency and safety of the NAS by supplementing the existing VOR Federal airway structure and providing alternative routing in the event of navigation aid (NAVAID) outages. The minimum IFR altitude in the area varies between 7,000 feet MSL and 9,300 feet MSL; however, the radar coverage in that area is not reliable below 12,000 feet MSL to 13,000 feet MSL. When NAVAID outages occur, due to the existing route and NAVAID structure, it is difficult to route aircraft between the Gillette VOR/DME and the Rapid City VORTAC. In this situation, aircraft flying at lower altitudes must climb up to be within radar coverage in order to get a more direct route to/from the VOR/DME and VORTAC. This is especially important during winter months because pilots encountering icing conditions at the higher altitudes need to descend, but are then lost from radar coverage. The proposed T-288 modification would alleviate this situation as well as enhance the NAS efficiency by adding an RNAV route option.

Low altitude RNAV routes are published in paragraph 6011 of FAA Order 7400.9V, dated August 9, 2011 and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The RNAV route listed in this document would be published subsequently in the Order.

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this proposed regulation: (1) Is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under Department of Transportation (DOT) Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority.

This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it expands RNAV route coverage to enhance the safe and efficient flow of traffic in the western United States.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, “Environmental Impacts: Policies and Procedures,” paragraph 311a and 311b. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.
