What is the initial action to take in case of a breakaway during aircraft towing?

The initial action to take in case of a breakaway during aircraft towing is to immediately apply the brakes on the towing vehicle and simultaneously communicate the emergency to all personnel involved in the towing operation. A breakaway is a situation where the tow bar unexpectedly disconnects from either the aircraft or the towing vehicle, resulting in a loss of control. The towing vehicle operator must apply the brakes firmly and smoothly to stop the vehicle as quickly and safely as possible. At the same time, the operator must use the radio or other communication methods to alert the ground crew, including the wing walkers and any other personnel involved, about the breakaway. This allows everyone to take appropriate actions to prevent further incidents, such as securing the aircraft, assessing the situation, and preventing anyone from approaching the aircraft or the disconnected tow bar until it is safe to do so. The priority is to bring the towing vehicle to a controlled stop and alert all relevant parties to the emergency.
