During power-on towing, the anti-collision switch should be set to which position?

• A. Wing
• B. Nose
• C. Tail
• D. Fuselage

Answer: (D)

During power-on towing you want the aircraft to be highly visible to everyone working around it and to approaching traffic. The anti-collision switch governs which lighting assemblies are energized, and selecting the fuselage position places the lighting along the aircraft’s centerline. This makes the anti-collision visibility most obvious to ground handlers and spotters around the nose and along the fuselage, no matter which direction you’re moving in. Wingtip or tail lighting can be harder to see in a busy ramp scene because those areas can be blocked by the tow tractor, aircraft structure, or equipment, and a nose-focused setting doesn’t give as broad visibility to people around the aircraft. So, the fuselage setting provides the most reliable, consistent visibility for safe towing.
