A system and a method include a flight control surface, an actuator configured to control motion of the flight control surface, and a brake configured to engage at least a portion of the flight control surface in response to the flight control surface disengaging from the actuator. The brake arrests unrestrained motion of the flight control surface when the brake engages the at least a portion of the flight control surface.

Systems and methods for controlling a flight control surface of an aircraft

Flight control surface actuation systems including skew detection systems and associated methods. A flight control surface actuation system includes a skew detection system configured to generate a skew detection signal that represents a skew condition of a flight control surface. In some examples, the skew detection system includes a skew lanyard and a detection mechanism assembly (DMA) configured to detect a lanyard displacement of the skew lanyard and to generate an analog lanyard displacement signal. In some examples, the skew detection system includes a hybrid sensing actuator that includes an actuator output and an actuator output position sensor directly coupled to the actuator output. Methods of utilizing a flight control surface actuation system include detecting a skew condition in the flight control surface utilizing DMAs and/or hybrid sensing actuators.
