Abstract
A digital surface position sensor includes a position sensor, an adaptable hardware input, and a processing circuit. The position sensor is adapted to be coupled to an aircraft flight control surface The adaptable hardware input provides an identification signal that identifies the aircraft flight control surface to which the position sensor is coupled. The processing circuit is configured to generate sensor actuator position data representative of flight control surface actuator position, determine flight control surface actuator position error, and generate a fault signal when the flight control surface actuator position error exceeds a predetermined threshold.
