Abstract
A flight control system for controlling the pitch of an aircraft having a vertical takeoff capability and an orientable lift direction may include a first device, to which a pitch command determined by a computing unit is applied, for actuating an element acting on the pitch of the aircraft. A second device of the flight control system receives an orientation order to actuate an element altering the orientation of the lift direction. Another device determines an orientation order for optimizing a flight parameter based on the pitch command determined by the computing unit. Yet another device subtracts from the pitch command the pitch contribution due to actuating the orientation element. The difference value acts as a pitch command to the first device.
