FAA Issues Advisory for GPS Interference Testing in Anchorage, Alaska
The Federal Aviation Administration (FAA) has issued a flight advisory warning pilots about scheduled GPS interference testing in the Anchorage, Alaska, area. This testing is set to occur from November 6-16, 2026. During these periods, GPS signals may become unreliable or completely unavailable, according to officials from the Alaska Airmen’s Association. The interference could also affect GPS-dependent systems such as the Wide Area Augmentation System (WAAS), Ground-Based Augmentation System (GBAS), and Automatic Dependent Surveillance-Broadcast (ADS-B) equipment. The testing is centered on the Ted Stevens Anchorage International Airport (PANC) VOR (TED) 025° radial at 12 nautical miles, with a potential advisory area covering a significant portion of south-central Alaska, extending outwards based on altitude. Pilots operating in this region are advised to review active NOTAMs before each flight, be prepared for potential GPS service loss, and utilize non-satellite navigation alternatives when necessary. ...
