| 释义 |
Anti-collision lights, also known as Beacon lights or Strobe lights are a set of lights required on every aircraft to improve visibility to others.[1] Historically they have used incandescent bulbs, but recently Light-emitting diodes have been used. Types of anti-collision lightBeaconBeacon lights are flashing red lights fitted on the top and bottom fuselage of an aircraft. Their purpose is to alert ground crew and other aircraft that an engine is starting up, running or shutting down, or that the aircraft is about to start moving. They spin to produce a flashing effect, increasing the chance they will be noticed. Beacon lights are bright enough to be seen from the ground, and can be used to identify aircraft from the ground in dark or overcast conditions where the plane itself isn't completely visible. StrobeStrobe lights are flashing white lights on the furthest left, right and back points of an aircraft. They are the brightest lights on the aircraft, and are used to signal that an aircraft is entering or approaching an active runway, or for visibility in dark, clear sky. They are turned off in cloud or fog, as they can further obscure the pilot's sight outside of the aircraft by reflecting off water particles.
