What is prohibited concerning the tow bar during operations?

The prohibition of crossing or riding on a tow bar that connects both the aircraft and the tow vehicle is rooted in safety concerns. When personnel cross or ride on a tow bar under those conditions, they intentionally place themselves in a potential hazard zone. If the tow vehicle moves unexpectedly or if there's a sudden engagement or disengagement of the tow bar, it could result in serious injury or even fatality. The tow bar is not designed to support the weight of personnel, and using it as a means of crossing or as a seat underscores a disregard for safety protocols. Maintaining a safe distance from the tow bar and ensuring personnel are clear of the operational area helps prevent accidents and promotes a culture of safety during ground operations.
