What are the various whine noises coming from the Boeing 787 cabin? Especially near the wing. I have seen tons of YouTube videos in which it has a noise during takeoff, or when flaps are being lowered or raised?
Other people have complained about this too. Boeing should rename the type to the "Whineliner".
The noise is caused by a hydraulic pump which is situated directly below the cabin. It mostly runs on takeoff and landing, but it can also run automatically at other times.
Dogs have been reported to need psychiatric treatment after being transported on a 787.
