When is it permissible to drive between a marshaller and an aircraft during the push-back or docking process?

Driving between a marshaller and an aircraft during the push-back or docking process is never permissible. This rule is in place to ensure the safety of all personnel and equipment involved. The marshaller's role is to provide clear signals to the aircraft and ensure that the area is free of obstacles before an aircraft moves. If a vehicle were to drive between the marshaller and the aircraft, it could create dangerous situations, potentially leading to collisions or endangering ground personnel.

Maintaining a clear line of communication and visibility between the marshaller and the aircraft is critical during these operations. Distracting or obstructing this interaction could lead to misunderstandings or accidents. Therefore, adherence to this rule is crucial for maintaining safety and operational integrity on the airside.
