Proposed Amendment to Alaskan VOR Federal Airway V-319, United States Air Navigation (RNAV) Routes, T-219 and T-269, and Revocation of Federal Colored Airway R-50; Alaska

Краткое содержание

This action proposes to remove Colored Federal airway, R-50, and amend Alaskan VOR Federal airway, V-319, and United States Air Navigation (RNAV) Routes T-219 and T-269 in Alaska. The modifications are necessary due to the planned decommissioning of the Nanwak Non- Directional Beacon (NDB) and Distance Measuring Equipment (DME) in Mekoryuk, AK, which provides navigation guidance for portions of the affected routes. The Nanwak NDB/DME (AIX) is to be decommissioned effective June 17, 2021 due to the high cost of maintenance.
