What must be done before parking equipment near an aircraft?

When parking equipment near an aircraft, chocking the aircraft is a critical safety procedure to ensure that the aircraft remains securely in position and does not inadvertently move. This step helps prevent accidents that could occur if the aircraft were to roll or shift while equipment is being parked or maneuvered near it.

Chocking provides a physical barrier that immobilizes the aircraft, allowing personnel to safely operate around it without the risk of movement. It is essential for maintaining a secure environment, particularly in busy ramp areas where various activities occur simultaneously.

While inspecting the equipment, giving clearance signals, and turning off engines are important safety protocols in their own contexts, the act of chocking directly relates to preventing movement of the aircraft itself, thus creating a safe zone for maneuvering equipment around it.
