In all my flying experience I have to say I haven't flown an airliner you could hear the actual flap movements (this is with the engines on I must add, all flap movements in the planes I fly are with engines on). I know of airliners you can hear the hydraulic pumps and ones that make audible noises as the flaps move, but not one where you can hear the things physically moving from a closed cockpit door. However, engines off just sitting there, ya you can hear almost anything moving. (I love doing the first flight of the day check on a 727 because you extend the spoilers and they make this awesome sound that I can't really describe but it sounds really really cool)
Pilot for a major US airline certified in the: EMB-120, CRJ, 727, 737, 757, 767, and A-320 and military, T-38, C-130, C-141, and C-5 along with misc. other small airplanes. Any questions, I'm here for you.
