How does one maintain a safe distance from aircraft on the airside?

Maintaining a safe distance from aircraft on the airside is crucial for ensuring the safety of both personnel and operations. The correct choice emphasizes the importance of adhering to established clearances and spatial guidelines as outlined in the AVOP guidelines. These guidelines are designed to provide specific measurements and procedures that all airside vehicle operators must follow to prevent accidents and ensure the safe movement of both vehicles and aircraft.

The established clearances help in creating a safe environment by reducing the risk of collisions and ensuring that vehicles do not encroach into the operational zones of aircraft. In this context, the AVOP guidelines serve as a comprehensive resource that outlines necessary protocols, signage, and markings that assist operators in maintaining a proper distance.

While some methods might seem practical, such as keeping the engine running or relying solely on visual judgment, they do not provide the structured safety measures needed on the airside. Similarly, following other vehicles closely could lead to situations where operators misjudge the distance required, increasing the risk of an incident. Therefore, adherence to the clearly defined spatial guidelines ensures that every operator is effectively contributing to a safer airside environment.
