US and Canada will use the same air traffic routes over North Dakota

The US Federal Aviation Administration proposes to establish a new air navigation route, Q-855, and remove an old one, J-549. This change will align US air traffic control with Canada's ongoing efforts to modernize its route structure.

For decades, air traffic control has relied on ground-based radio beacons to define flight paths. Modern aircraft use satellite navigation, which allows for more direct and efficient routes. This small change is part of a larger, quiet shift towards a unified, satellite-based air traffic system across North America.
