What is the signal to stop the tow operation?

• A. Cutting across the neck
• B. Raising both arms overhead
• C. Shouting 'stop'
• D. Waving the tow line

Answer: (A)

During aerotow, clear visual signals are used so the tow pilot can respond immediately. The gesture of crossing a hand across the neck is the standard stop signal. It’s unambiguous, easy to see from a distance, and specifically communicates to stop towing and release the tow rope so the glider can separate. Verbal cries or other motions aren’t as reliable in the noisy, fast-moving environment, and waving the tow line or raising arms overhead can be misread or not noticed in time. So this neck-cutting gesture is the most effective and recognized way to halt tow operations promptly.
