Airfield ground vehicle (GND)
WHAT AIRCRAFT IS GND?
GND is the ICAO aircraft type designator for the Airfield ground vehicle — not a plane — an airfield vehicle with a transponder. A follow-me car, a sweeper, possibly a man called Alan in a van. When you tap a blip on a radar scope, flight tracker, or spotting app and see "GND", this is what's overhead.
