What is considered a 'circle of safety' around parked aircraft?

A 'circle of safety' around parked aircraft is defined as a clear buffer zone to ensure the safety of personnel and avoid accidents or injuries while moving around aircraft. This zone is established to help ground personnel maintain a safe distance from the aircraft during operations, minimizing risks associated with moving equipment, debris, and the aircraft itself.

The chosen distance of 10 feet is deemed appropriate because it provides a balance between maintaining a safe distance and allowing for practical movement near the aircraft. It is crucial for ground personnel to be aware of their surroundings and follow the established safety protocols, particularly when it comes to navigating around aircraft that may be sensitive to interference or external contact.

In contrast, other distances like 5 feet may not allow sufficient space for safe movement, especially in busy aircraft parking areas, while 15 feet or 20 feet may be unnecessarily excessive, potentially complicating operations and increasing the risk of accidents due to limited access to aircraft. Thus, a 10-foot circle of safety effectively serves its purpose of protecting personnel while ensuring that ground operations can proceed smoothly.
