WebThe wings of a bird are flapping, but the wings of an airplane are fixed and cannot be flapping. So birds are not afraid of stall, and even use stall (differential pressure resistance) to generate more force to reduce speed. Note that the bird will flap its wings in the direction of speed when landing. Share. Webof the wings themselves.
