AMAN: Abrupt Manoeuvre - The intentional abrupt maneuvering of the aircraft by the flight crew.
- This category includes the intentional maneuvering of the aircraft to avoid a collision with terrain, objects/obstacles, weather or aircraft (note: the effect of intentional maneuvering is the key consideration).
- Abrupt maneuvering may also result in a loss of control or system/component failure or malfunction. In this case the event is coded under both categories (e.g., AMAN and LOC-I, AMAN and SCF-NP, or AMAN and SCF-PP).
- Abrupt maneuvering may also occur on ground, examples include hard braking maneuver, rapid change of direction to avoid collisions etc.
