Abstract: Disclosed is a system for monitoring wing control on an aircraft that includes a plurality of radio frequency identification device (RFID) tags attachable to a movable wing portion. The system includes a RFID reader attachable to a stationary wing portion and configured to communicate with at least two RFID tags, and a controller. The controller includes a processor connected to the RFID reader. The processor transmits at least two carrier signals via the RFID reader to the at least two RFID tags. Each of the transmitted carrier signals have a different carrier frequency. The processor also receives at least two reflected signals from the at least two RFID tags. The processor determines, based on the reflected signal from the at least two RFID tags, at least one of a motion of the movable wing portion and a distance of the movable wing portion.
