@aviation.with.harry: Ever wondered what the lights in the centre of the runway actually mean? The lighting at airports goes far beyond allowing pilots and ground staff to see at night, changes in colour are used to give different information - Runway centreline lights are a great tool to show pilots how much runway they have left to go, especially in poor visibility where they may not be able to see the end! It’s also great for vehicles who are driving on the runway in poor weather for the same reasons. #aviation #aviationfacts #Runway #airport #airportlife #pilots #studentpilot #flightcrew #pilots #agl #planes #airports #airportfacts
