This action proposes to revoke Colored Federal airway, B-25. The revocation is necessary due to the planned decommissioning of the Glenallen Non-Directional Beacon (NDB) Gulkana, AK, which provides navigation guidance for the affected route. The Glenallen NDB is to be decommissioned effective September 8, 2022 due to the high cost of maintenance.
