Availability and Summary of Documents for Incorporation by Reference This document proposes to amend FAA Order JO 7400.11F, Airspace Designations and Reporting Points, dated August 10, 2021, and effective September 15, 2021. FAA Order JO
7400.11F is publicly available as listed in the ADDRESSES section of this document. FAA Order JO 7400.11F lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.
Background In 2003, Congress enacted the Vision 100-Century of Aviation Reauthorization Act Pub L., 108176, which established a joint planning and development office in the FAA to manage the work related to the Next Generation Air Transportation System NextGen. Today, NextGen is an ongoing FAA-led modernization of the nations air transportation system to make flying safer, more efficient, and more predictable.
In support of NextGen, this proposal is part of a larger and comprehensive Troute modernization project in the state of Alaska. The project mission statement states: To modernize Alaskas Air Traffic Service route structure using satellite based navigation Development of new T-routes and optimization of existing T-routes will enhance safety, increase efficiency and access, and will provide en route continuity that is not subject to the restrictions associated with ground based airway navigation.
As part of this project, the FAA
evaluated the existing Colored Airway structure for: a Direct replacement i.e., overlay with a T-route that offers a similar or lower Minimum En route Altitude MEA or Global Navigation Satellite System Minimum En route Altitude GNSS MEA; b the replacement of the colored airway with a T-route in an optimized but similar geographic area, while retaining similar or lower MEA; or c removal with no route structure T-route restored in that area because the value was determined to be insignificant.
The aviation industry/users have indicated a desire for the FAA to transition the Alaskan en route navigation structure away from dependency on Non-Directional Beacons NDB, and move to develop and improve the RNAV route structure.

The FAA proposes to amend RNAV
route T275 by extending it to the south to provide an alternate routing for Colored airway B7. B7 utilizes Oscarville, AK, OSE and Cape Newenham, AK, EHM NDBs, which are on the scheduled decommission list.
Additionally, the proposed amendments would provide for lower MEAs while also ensuring that the appropriate route criteria is met along the entire route.
The Proposal The FAA is proposing an amendment to 14 CFR part 71 to amend RNAV route T275 in the vicinity of Bethel, AK in support of a large and comprehensive Troute modernization project for the state of Alaska. The proposed route changes are described below.
T275: T275 currently extends from Bethel, AK, BET to Unalakleet, AK, UNK. The FAA proposes to extend the route south from BET to provide alternate navigation for Colored airway B7. The segment between BET and UNK would also change adding an additional turn point, taking the airway slightly to the west to allow for better route connectivity with proposed and current T-routes.
United States Area Navigation Routes are published in paragraph 6011 of FAA
Order JO 7400.11F dated August 10, 2021 and effective September 15, 2021, which is incorporated by reference in 14
CFR 71.1. The RNAV route listed in this document would be published subsequently in the Order.
FAA Order JO 7400.11, Airspace Designations and Reporting Points, is published yearly and effective on September 15.
Regulatory Notices and Analyses 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. It, therefore: 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.
