Canadian air traffic control is removing old radio beacons, changing US flight paths

Canada is decommissioning several old radio navigation beacons that planes use to find their way. This means the US Federal Aviation Administration must change several established flight routes over the northcentral United States.

For decades, planes have navigated using ground-based radio beacons. These beacons are expensive to maintain and are being replaced by satellite-based navigation systems. This change means pilots will rely more on GPS and less on fixed ground signals, making air travel more efficient and flexible.
