Patent ID: 8359130

Claim:
A method for attenuating vertical turbulence encountered by an aircraft during flight, the method comprising the steps of: a) determining, by a wind determination device, a vertical wind component existing outside the aircraft at a current position of said aircraft; b) determining, by a severity level determination unit, according to said determined vertical wind component, a severity level of the vertical turbulence existing outside the aircraft at said current position as a function of deviation in vertical load between a load factor at equilibrium for the aircraft and a load factor resulting from the vertical turbulence; c) calculating, by a control unit, according to said determined vertical wind component, at least one control order to control at least one controllable movable member configured to act on aircraft lift, said control order controlling amplitude of the vertical load generated on the aircraft by the vertical turbulence; d) determining, by said control unit, existence of activation conditions based on verification of the severity level of the vertical turbulence and deviation between a value of the control order and a predetermined threshold value; and e) transmitting, by said control unit, said control order to at least one actuator of said at least one controllable movable member, wherein: said control order is transmitted to said at least one actuator of said at least one controllable movable member, upon the determination of the existence of said activation conditions.
