The Federal Aviation Administration (FAA) is proposing a rule change that would affect several aviation routes in the Northwestern United States. Due to the upcoming decommissioning of the VOR navigational aid in Whatcom, WA, the FAA plans to revoke Jet Route J-534 and VOR Federal Airway V-349 entirely. The proposal also includes amendments to VOR Federal Airways V-23 and V-165, as well as the establishment of a new Canadian Area Navigation Route, T-645. This is part of the FAA's effort to adapt to the transition towards more modern navigation systems.
Simple Explanation
The FAA wants to change some airplane paths in the Northwest U.S. because they're turning off an old guiding tool in Washington. They're going to stop using two old paths and make changes to others, plus add a new path into Canada to help planes find their way better.
