Abstract
The disclosed embodiments concerns a process for limiting the control surface steering angle of an aircraft, including operations to: determine the maximum permissible steering angle in function of the speed of the aircraft, detect a yaw configuration of the aircraft following a first order for control surface deflection at a maximum steering angle and a first direction, apply a limit to the maximum permissible steering angle. The disclosed embodiments also concern a system for implementing the process.

Process for limiting the steering angles of an aircraft's control surface, the process comprising:
- using a first device to acquire a speed of the aircraft;
- using a second device to determine a maximum permissible steering angle as a function of the speed of the aircraft;
- supplying a current position of the control surface from a third device;
- using an electronic circuit to detect a yaw configuration of the aircraft and an order for control surface deflection at the maximum permissible steering angle by using a logical circuit to verify that two successive control surface deflections are in opposite directions and at the maximum permissible steering angle;
- and
- using a computer to apply a limit to the maximum permissible steering angle.
System for limiting the steering angle of a control surface of an aircraft, including:
- a device for acquiring the speed of the aircraft,
- a device for determining the maximum permissible steering angle as a function of the speed of the aircraft,
- a device for acquiring the current position of the control surface, wherein the system includes:
