A method and device of dynamically reducing the buffeting of an airplane. The method is carried out by detecting a risk of buffeting of the airplane in flight by a monitor. At least one control surface is turned by an actuator arranged at a trailing edge of each wing of the airplane. The control surface is turned, at a predetermined respective rate of turn, into a predetermined respective position to modify lift profile of the wing along a wingspan length to reduce lift in at least one buffeting-generating region of each wing.
