Why is radio communication vital between the tug operator and the wing walkers during aircraft towing?

Radio communication is vital between the tug operator and the wing walkers during aircraft towing to ensure real-time coordination and communication, enabling the safe movement of the aircraft. Wing walkers are positioned at the wingtips to visually monitor the aircraft's clearance from obstacles, such as other aircraft, buildings, and ground equipment. They can see areas that the tug operator cannot, due to blind spots or the aircraft's size. Radio communication allows the wing walkers to immediately alert the tug operator of any potential hazards or obstructions, allowing the operator to adjust the aircraft's path or stop the towing operation if necessary. This constant communication loop significantly reduces the risk of collisions and ensures a safe and efficient towing process. Furthermore, radio communication provides a clear and reliable means of communication, especially in noisy environments or when visual signals may be obscured.
