Abstract:
1. A method of dynamically reducing the buffeting of an airplane, comprising the steps of: detecting a risk of buffeting of the airplane in flight by a monitor; and turning, by an actuator, at least one control surface arranged at a trailing edge of each wing of the airplane, wherein: said at least one control surface is turned, at a predetermined respective rate of turn, into a predetermined respective position to modify lift profile of the wings along a wingspan length to reduce lift in at least one buffeting-generating region of each wing, the predetermined respective rate of turn is between 0.2°/s and 2°/s and the predetermined position is at an angle of between −5° and +5′ relative to initial position, prior to turning, and the risk of buffeting is detected by the monitor, when the following two conditions are simultaneously satisfied: altitude of the airplane is above a predetermined altitude; and a G-factor command of the airplane is above a predetermined G-factor.
