A physical beacon for planes in Lebanon, NH is replaced by GPS coordinates

The Federal Aviation Administration is changing how it defines a specific point in the airspace over Lebanon, New Hampshire. Instead of referencing a physical radio beacon, it will now use exact GPS coordinates.

For decades, air traffic control relied on ground-based radio beacons to guide planes. As these physical beacons age and are decommissioned, the system is slowly shifting to a purely digital, satellite-based approach. This small change in Lebanon, NH, is one tiny step in that larger, quiet transition.
