What Creates The Strange Sounds You Hear Prior To Take Off And Landing?

Answer»

The drilling SOUND you hear during landing and take-off is the sound of the flaps and slats being extended on the wings. These PANELS are DRIVEN by a screw mechanism that CAUSES the SOUNDS; it increases the area and curvature of the wing when extended to facilitate low-speed flying.
