Hanghull

Hanghull is a type of aerial maneuver performed by aircraft. It involves a significant loss of altitude while the aircraft maintains a constant angle of attack, typically close to that required for a stall. During a hanghull, the pilot intentionally uses the aircraft's control surfaces to disrupt airflow over the wings, causing a controlled descent. This maneuver is often used for rapid altitude reduction or to reposition the aircraft in a tactical situation.

The term "hanghull" itself is not widely recognized in standard aviation terminology, and may be a colloquial or niche term. More common terms that describe similar actions include a "controlled descent," a "steep dive," or a "rapid descent with high angle of attack." The precise execution and controllability of such a maneuver are highly dependent on the specific aircraft type and the pilot's skill. It is crucial that any such maneuver be performed within the aircraft's structural limits and aerodynamic capabilities to avoid uncontrolled flight or structural failure. Training in such advanced maneuvers is typically reserved for military pilots or those involved in specialized aviation activities. The primary goal of a hanghull, if it is indeed a defined maneuver, is to achieve a rapid and controlled loss of altitude without entering an uncontrolled stall or dive.
