An electronic and mechanical control system that ensures an aircraft follows a pre-programmed flight plan. The autopilot (automated pilot) monitors the course and speed of the aircraft and corrects any deviations from the flight plan. Systems range from simple wing-levellers to computer-operated units consisting of a gyroscope; an electric servomechanism; and an accelerometer, which measures the acceleration of the aircraft.
