Vapour
Hi people, just a quickie, im PPL, IMC, and night rated pilot, currently enjoying flying the warrior and traumahawk, and have a question for you. when taking off in say a 767 you look out of the window over the wing, (cos im always in cattle class), and when the aircraft rotates there is a huge streamer of vapour off the top of each engine, can you tell me precisely what causes this ? i have seen passengers who didnt know that this is normal panic when they saw it , believing that it was smoke etc ! your explanation much appreciated, cheers.
