An aerodrome beacon, airport beacon, rotating beacon or aeronautical 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.
Rotating beacon may refer to: Aerobeacon, a light assembly used to create a fixed or flashing signal visible over long distances; Aerodrome beacon, a beacon installed at an airport or aerodrome to indicate its location to aircraft pilots at night; Airway beacon, a rotating light assembly mounted atop a tower
Anti-collision lights, also called beacon lights or strobe lights, are a set of lights required on every aircraft to improve visibility to others, as well as collision avoidance measures by warning other pilots. [1] Historically they have used incandescent light bulbs, but recently LED lamps have been used.
DCB-224 - Two Harbors Light. The model DCB-224 is a high-power spotlight designed and built by Carlisle & Finch. [1] Originally intended for use as an aerodrome beacon, it was also widely used in marine lighthouses. Depending on the type of bulb installed, the beam could be seen for 18 to 26 nautical miles (33 to 48 km).
An airway beacon (US) or aerial lighthouse (UK and Europe) was a rotating light assembly mounted atop a tower. These were once used extensively in the United States for visual navigation by airplane pilots along a specified airway corridor .
The flashing light signature seen by the observer has been achieved by rotating a lens system. Since LEDs can be flashed on and off without degrading their lives, it is likely the VRB-25 is the last use of rotating beacons in lighthouses.
