What is the only safe way to move most aircraft while on the ground and not running?

The correct approach for moving most aircraft on the ground while they are not running is by using a tow tractor. This method is specifically designed for this purpose and ensures safe and efficient movement of aircraft.

Tow tractors are equipped with the proper attachments and power to maneuver aircraft smoothly, reducing the risk of damage to the aircraft and minimizing the physical strain on personnel. They provide better control over the aircraft's movement, allowing operators to follow safe procedures while also adhering to the necessary ground handling protocols.

For safety and efficiency, employing a tow tractor mitigates the risks associated with the other options. Forklifts, for instance, may not have the appropriate design to handle aircraft without risk of causing structural damage. Manual push methods could lead to uneven distribution of force, increasing the potential for accidents. Dragging by hand is highly discouraged due to the risk of injury and could result in damage to the aircraft and surrounding areas. Thus, using a tow tractor is recognized as the safest and most effective method for aircraft movement on the ground.
