Which of the following best describes the action required by towing safety rules regarding stopping and starting the tow vehicle?

• A. Always stop and start abruptly to maneuver quickly
• B. Never stop or start suddenly under any circumstance
• C. Stop only when fully loaded
• D. Avoid stopping and starting suddenly

Answer: (D)

Smooth, controlled motion of the tow vehicle is essential when moving an aircraft. Stopping and starting abruptly transfers sudden, high forces through the towbar and the nose gear, which can shake the aircraft, loosen chocks, strain equipment, or put ground crew at risk. The safest rule is to avoid abrupt changes in speed—accelerate and brake gradually, keep a steady pace, and plan maneuvers so you don’t have to yank the controls to reposition the aircraft. This approach helps maintain balance, reduces wear on the tow system, and enhances overall safety.

Abrupt starts or stops are unsafe because they create shock loads; an absolute ban on any stopping or starting is impractical in real operations, and stopping only when fully loaded misses everyday safety needs and control requirements during towing.
