Which light indicates the aircraft is ready for nosewheel towing when at the nose gear?

• A. Green towing light
• B. Amber caution light
• C. Red warning light
• D. Blue information light

Answer: (A)

When guiding ground handling, status lights at the nose gear tell the crew when towing is allowed. The green towing light is the signal that the aircraft is prepared and cleared to be moved by a tow vehicle. It means the required safety checks are in place—parking brake released, steering unlocked, towbar connected—and it’s safe for the tug to start pulling. The other lights indicate different conditions: amber for caution or a condition that must be resolved, red for a warning or stop, and blue for general information—none of which indicate that towing is approved. So the green towing light is the definitive cue that nosewheel towing can begin.
