That’s an airport beacon.

I think it’s on all the time, not just when the airport’s being controlled.

It’s a visual aid for pilots. It basically tells you the location of an airport which is especially useful at night.


Like what the others say, airport beacon. The beacon is on in IFR or at night.

Also the color code is to identify the airport… green/white=civil airport, green/white/white=military airport, white/red I think is hospital helipad… something like that.

@American_Ranger… Ranger, Google is your friend. Here’s a “Wikileaks’s” extract.
" An aerodrome beacon or rotating beacon is a beacon installed at an airport or aerodrome to indicate its location to aircraft pilots at night.

“An aerodrome beacon is mounted on top of a towering structure, often a control tower, above other buildings of the airport. It produces flashes similar to that of a lighthouse. Airport and heliport beacons are designed in such a way to make them most effective from one to ten degrees above the horizon; however, they can be seen well above and below this peak spread. The beacon may be an omnidirectional flashing xenon strobe, or it may be an aerobeacon rotating at a constant speed which produces the visual effect of flashes at regular intervals. Flashes may be of just a single color, or of two alternating colors.” Continue the text in Wiki for color codes, flash sequence etc"
