AIRPORT ROTATING BEACON
This reproduces published FAA reference text for study. It does not replace the current official FAA publication or regulation.
A visual NAVAID operated at many airports. At civil airports, alternating white and green flashes indicate the location of the airport. At military airports, the beacons flash alternately white and green, but are differentiated from civil beacons by dualpeaked (two quick) white flashes between the green flashes.
