A Canadian navigation beacon moved, so a US flight path changed

The US Federal Aviation Administration changed a flight path over the northcentral US. This happened because a Canadian navigation beacon moved.

Air traffic controllers and pilots rely on a network of ground-based radio beacons to define flight paths. When one of these beacons moves, the paths that rely on it must also change. This specific change is part of a larger effort by Canada to modernize its navigation system, which means more such adjustments are likely in the future.
