How does exceeding the maximum safe towing speed affect the controllability of an aircraft during towing?

Exceeding the maximum safe towing speed reduces the controllability of an aircraft during towing primarily due to the increased forces acting upon the aircraft's structure, landing gear, and the tow bar itself. Higher speeds introduce greater aerodynamic drag, which is the force resisting the aircraft's movement through the air. This drag creates instability, making it harder to maintain a straight path and increasing the risk of oscillations or swaying. Furthermore, the forces on the tow bar increase exponentially with speed. If the speed is too high, the increased force can exceed the tow bar's design limits or the shear pin's capacity, potentially leading to a failure. The aircraft's steering mechanism, designed for slow movements, may not respond effectively at higher speeds, reducing the operator's ability to make precise corrections. Moreover, braking distances increase significantly at higher speeds, making it more difficult to stop the aircraft safely in an emergency situation. All these factors combine to compromise the operator's control over the aircraft, increasing the likelihood of accidents or damage to the aircraft and surrounding equipment.
