The latest edition of the FAA SatNavNews includes a discussion* of the agency’s plans to shut down many VORs as the aviation world shifts to GPS-based navigation. The article, on pages 5-8 of the Summer 2012 issue (PDF), includes graphics that show how shutting down many of the VORs in the eastern two-thirds of the continental U.S. will change the existing airway system.
