Answer 41

Ailerons are the primary flight control surfaces that move the aircraft about the longitudial axis. On the wing on which the aileron trialing edge moves downward, camber is increased and life is increased. (FAA-H-8083-31-V1) P.52

Answer 47

(TQ)Ailerons are the primary flight control surfaces that move the aircraft about the longitudinal axis. In other words, movement of the ailerons in flight causes the aircraft to roll. (TQ) When the aileron on one wing deflects down, the aileron on the opposite wing deflects upward.
