The US Federal Aviation Administration is revoking two air routes and changing a third in Alaska. This is happening because a specific radio beacon used for navigation has been shut down.
Why it matters
Air routes are like invisible highways in the sky. When a ground-based navigation aid shuts down, the routes that relied on it must also change. This means pilots flying in these parts of Alaska will need to use different routes or rely more on satellite navigation.
The signal
Watch for any new notices to airmen (NOTAMs) or updated flight charts that reflect these changes, and whether pilots report any new challenges in these areas.
