Engineering:Pitch drop-back
From HandWiki
Short description: Aerodynamic phenomena
Pitch drop-back is the phenomena by which an aircraft which is perturbed in flight path angle from its trim position by a step input exhibits an output which is indicative of a second order system.[1]
A pilot who actuates an elevator input may find that the aircraft then "droops" or "drops back" to a position further toward the start position. The phenomenon is particularly marked in tilt-rotor aircraft.[2] Pitch drop-back may be controlled using a Stability Augmentation System or Stability Control and Augmentation System.[3]
