Alaska is closing down some of its old air navigation routes

The US is proposing to change several federal airways in Alaska. This means some old radio beacons that guide planes are being turned off.

For decades, air travel relied on ground-based radio signals to guide planes. These signals created invisible highways in the sky. As technology advances, planes increasingly use satellite navigation, making the old radio beacons less necessary. This change reflects a broader shift in how air traffic is managed, moving away from fixed ground infrastructure.
