Abstract
An electric system for controlling a depth aerodynamic surface (1) of an aircraft. The system includes an attitude sensor (3) and an incidence sensor (6). A calculation means (7) in communication with the sensor controls a motor (4) so as the depth aerodynamic surface of the aircraft reaches an incidence according to a programmed depth control law. The system utilizes an incidence protection device (35) able to control the incidence of the aircraft within a range of values limited upwards by a limit value, beyond which the aircraft could become unstable.
