Patent ID: 8083178

Claim:
A method for piloting an aircraft, in which the aircraft comprises two symmetric wings, with each wing having: movable lift-enhancing aerodynamic surfaces, configured to provide said wings either a smooth configuration, or at least one enhanced-lift configuration; and roll control ailerons, configured to provide a neutral position that corresponds to a zero deflection, when said wings exhibit said smooth configuration, the method comprising the steps of: providing the enhanced-lift configuration to said wings: when incidence and speed of the aircraft are respectively less than an incidence threshold and greater than a speed threshold, a first state corresponding to a position deflected upwards by an angle such that roll effectiveness of said ailerons is preserved; and when incidence of the aircraft is equal to or greater than said incidence threshold or when the speed of the aircraft is equal to or less than said speed threshold, a second state corresponding to at least one of: a first downward deflection value corresponding to maximum finesse (Fmax) of the aircraft during takeoff or re-takeoff phase, and a second downward deflection value corresponding to optimal lift of the aircraft during landing phase.
