When passing underneath the aircraft, which area should you steer clear of?

When passing underneath the aircraft, it is crucial to steer clear of the tailhook and large flight controls. This area poses significant safety risks due to the potential for movement or activation. The tailhook is designed to catch cables on an aircraft carrier during landing, and it may extend or retract unpredictably. The large flight controls, such as ailerons and elevators, can also be in motion during pre-flight checks and ground operations. They may not be immediately visible or could be operated by someone on the flight deck, creating hazards for personnel passing underneath.

Maintaining a safe distance from these components is vital to prevent injury, especially since they can move rapidly and without warning. Safety protocols emphasize awareness of aircraft operations and the potential risks associated with large, moving parts during all phases of aircraft handling.
