What is the minimum distance to maintain from an obstacle when NOT using a marshaler or wing walker?

The minimum distance to maintain from an obstacle when not using a marshaler or wing walker is set at 10 feet to ensure safety and avoid potential collisions. This distance takes into account the size of the aircraft and the necessary margin for error during maneuvers. Maintaining a minimum of 10 feet allows pilots to operate with a buffer that reduces the risk of contacting obstacles or other aircraft, which is particularly crucial in tight operational environments.

Choosing a distance that is too small could lead to hazardous situations where an aircraft might inadvertently come too close to objects that could cause damage or endanger personnel. The specified distance strikes a balance between operational efficiency and safety protocol, ensuring that there is enough space for the pilot to visually confirm their surroundings without the assistance of a marshaler or wing walker.
