When an aircraft is being taxied within 25 feet of an obstruction, what safety measure is required?

• A. One wing walker per wing tip
• B. Wing walkers on the aircraft deck
• C. A minimum of one wing walker for each wing tip
• D. No wing walkers required

Answer: (C)

Wing tip clearance is the critical safety measure when taxiing close to obstacles. Having at least one wing walker at each wing tip ensures both sides of the aircraft are watched and guided, so neither wing tip can come into contact with an obstruction as you maneuver within 25 feet. This independent supervision on both wings prevents a wingtip strike that could occur if only a single observer covered the whole airplane, and it means watchers aren’t perched in an aircraft deck position where they can’t effectively see the ground. No wing walkers or inadequate coverage isn’t acceptable for this close clearance situation.
