Function of the outboard ailerons on the B-727 is based on position of outbard flaps and not speed. Movement of outoard ailerons commence with initial flap extion and increases as outboard flaps are extended to about the 15 degree position. The outboard ailerson are bused via cable from a concentric pully located just aft of the outboard ailerons when input is provided to the inboard ailerons.
