In aerobatics, the Cobra maneuver (often shorted to just the Cobra), also named dynamic deceleration, among several other names, is a dramatic and demanding maneuver in which an airplane flying at a moderate speed suddenly raises the nose momentarily to the vertical position and slightly beyond vertical with an extremely high angle of attack, momentarily stalling the plane and making it a full-body air brake, before dropping it back to normal, during which the aircraft does not change effective altitude.
