An aircraft flight control surface actuation control system includes an actuator control unit and a flight control module. The actuator control unit includes at least two independent actuator control channels to generate limited authority flight control surface actuator commands based on pilot inceptor position signals and flight control augmentation data. The flight control module supplies the flight control augmentation data to each of the independent actuator control channels, determines operability of each of the actuator control channels and, based on the determined operability of each independent actuator control channel, selectively prevents one of the independent actuator control channels from supplying the limited authority flight control surface actuator commands. The flight control module may also generate full authority flight control surface actuator commands for supply to flight control surface actuators.
