Which indication confirms that the aircraft is secured from moving?

The indication that confirms the aircraft is secured from moving is when chocks are inserted. Chocks are physical blocks that are placed against the wheels of the aircraft to prevent it from rolling or moving unexpectedly. In the ramp environment, safety is a top priority, and ensuring that the aircraft is securely in place is crucial when loading, unloading, or performing maintenance.

While engaging the brakes, turning off the engines, and having locked wheels can contribute to the aircraft being stable and stationary, chocking the wheels is a definitive action specifically aimed at preventing movement. Chocks serve as a mechanical method of securing the aircraft, providing visual and physical confirmation that the aircraft is in a safe position, particularly during ground operations.
