Abstract: The system includes a plurality of engines that generate a thrust of an aircraft, each of the engines controlled by a first controllable actuator. A plurality of brakes reduce the speed of the aircraft when it is taxiing, each of the brakes controlled by a second controllable actuator. A control unit generates a piloting setpoint that relates to the longitudinal behavior of the aircraft. A central processing unit automatically determines, from the piloting setpoint, a plurality of individual control commands that are applied automatically to the first and second actuators and used to satisfy the piloting setpoint and a usage objective for the actuators.

Abstract: A piloting device may include a section for generating control orders for the control surfaces acting on the yaw movement of an aircraft. A central unit determines an instruction to rotate the aircraft, based on control orders, and determines a global moment to be applied to the aircraft about the yaw axis so that the aircraft performs the rotation instruction. The central unit divides the global moment into a sum of elementary moments and computes, for each control surface, the instruction to be applied to its actuator so that the latter generates the associated elementary moment.

Abstract: The system includes a plurality of engines (m1 to mn) designed to generate a thrust of the aircraft, each of said engines (m1 to mn) being controlled by a first controllable actuator (A1 to An), a plurality of brakes (F1 to Fm) designed to reduce the speed of the aircraft when it is taxiing, each of said brakes (F1 to Fm) being controlled by a second controllable actuator (B1 to Bm), a control unit (2) designed to generate a piloting setpoint which relates to the longitudinal behavior of the aircraft, and a central processing unit (3A, 3B) for automatically determining, from the piloting setpoint, a plurality of individual control commands which are applied automatically to the first and second actuators (A1 to An, B1 to Bm) and which are used to satisfy the piloting setpoint, and a usage objective for the actuators.

Abstract: The piloting device (1) comprises means (2A, 2B) for generating orders for the control of control surfaces (3A, 3B, 3C, 3D) capable of acting on the yaw movement of the aircraft and each controlled by at least one actuator (4A, 4B, 4C, 4D), and a central unit (UC) which comprises means (5A, 5B) for determining an instruction to rotate the aircraft, based on control orders, means (6) for determining a global moment having to be applied to the aircraft about the yaw axis so that the aircraft performs the rotation instruction, means (7) for dividing this global moment into a sum of elementary moments, and means (7) for computing, for each of the control surfaces (3A, 3B, 3C, 3D), the instruction to be applied to its actuator (4A, 4B, 4C, 4D) so that the latter generates the associated elementary moment.
