What is the minimum distance an aircraft should maintain from obstructions without wing walkers present?

The minimum distance an aircraft should maintain from obstructions without wing walkers present is 25 feet. This distance is established to ensure safety during ground operations. Maintaining a buffer zone helps prevent accidents that could occur due to unforeseen movements of the aircraft or unexpected obstructions. Wing walkers are typically present to help guide and monitor the aircraft's movement in proximity to other objects; without them, a larger margin of safety is necessary. This standard helps protect both the aircraft and the personnel on the ground, minimizing the risk of collisions or damage to the aircraft and surrounding equipment.
