A320 "whirring"
Hi, and I hope I've posted this in the right section!
Here goes then,
Been on a few A320s and while the baggage is being loaded etc. I've heard a slight whirring sound from underneath, around the middle of the a/c! Sounds like a screw jack turning or the like, but really I haven't a clue what it is!
Any help would be appreciated here! Cheers!
