Wing walkers are required when towing in restricted areas where clearance is less than how many feet when towing with NVG?

• A. 25 feet
• B. 50 feet
• C. 75 feet
• D. 100 feet

Answer: (B)

Wing walkers are used during tow with NVG because Night Vision Goggles limit depth perception and awareness of surroundings, making precise wingtip clearance in tight spaces risky. In restricted areas, the safety margin must be maintained, so if the clearance between the wing tips and obstacles is less than 50 feet, wing walkers are required to guide and alert the towing team. The 50-foot threshold provides enough margin for an observer to detect potential contacts and communicate with the tow crew under NVG conditions. The other distances would not align with this safety standard for NVG towing in restricted areas, so the appropriate requirement is when clearance is under 50 feet.
