What is the purpose of chocks during ground operations?

The purpose of chocks during ground operations is to prevent aircraft movement. Chocks are wedge-shaped devices placed at the wheels of an aircraft to secure it in position. They are essential for maintaining safety when the aircraft is parked, loaded, or undergoing maintenance, as they help to ensure that the aircraft does not roll or move unexpectedly.

By immobilizing the aircraft, chocks serve as a critical safety measure, particularly given the size and weight of most military aircraft. This is especially important during various operations on the ground where stability is necessary, such as when ground crews are working near or under the aircraft. Other options, such as enhancing mobility or facilitating towing, do not align with the primary function of chocks, which is to provide a stronghold against inadvertent movement.
