The FAA has issued Letters to Airmen outlining plans to decommission the Nondirectional Beacons (NDBs) at the Gulkana (GKN), Mekoryuk (MYU) and Noatak (WTK) airports. In all three cases, the decommissioning’s are for navaids that have failed, and have been out of service for some time. Even though they are non-functional, they serve as fixes that are part of the airway structure, or are components of instrument approaches. If the removal of these navaids impacts your operation, please let the FAA know, using the contact information provided below.
Moving to Space Based IFR Infrastructure
While the FAA is moving to a space-based IFR system, NDBs in some locations are still serving not only as the basis for instrument approach procedures, but as anchor fixes for IFR airways. Last year AOPA was part of an industry group that looked at the IFR Enroute infrastructure in Alaska. Working with the Alaska Air Carriers Association, Alaska Airmen Association, National Business Aviation Association and other organizations, the group delivered formal recommendations to the FAA. The topics covered in the report were wide ranging including sections acknowledging the role NDBs play in the enroute environment, and expressed concern that some GPS based T-Routes have a much higher Minimum Enroute Altitude than the NDB-based colored airways. One of the recommendations called for the FAA to consider operator impacts before decommissioning any airway supported by NDBs. Responding to a Letter to Airmen is one mechanism that the FAA uses to collect user feedback.
This specific working group was only tasked to look at the enroute infrastructure, but acknowledged that NDBs in some locations still serve an operational role in the terminal environment, which should also be considered before these stations are decommissioned.
User input needed
The FAA is struggling to move into the space-based, NextGen era, balancing the need to keep existing “legacy” systems in place, while obtaining funding to stand up new infrastructure. AOPA and others are pushing FAA to expand the network of ADS-B ground stations in Alaska, to provide a “minimum operational network” across the state. Decommissioning legacy navigation aids is one way to free up resources, but only after the operational needs of the users have been considered. FAA is asking for our feedback on these three stations. If you fly to these areas, let the FAA know if removing these NDBs impacts your operations. Please contact:
