What is the usual maximum aircraft weight that a tractor can handle based on drawbar pull?

The correct answer is based on the general principle that the maximum aircraft weight that a tractor can handle is typically about ten times the drawbar pull it can generate. This factor considers the capabilities of the tractor in terms of both its mechanical strength and its ability to safely tow or maneuver an aircraft without exceeding its operational limits.

When calculating the maximum weight, it's essential to factor in the resistance encountered, such as friction from the wheels and the ground surface. The tenfold multiplier allows for a margin that supports effective handling while ensuring safety and preventing potential equipment failure or loss of control.

Using a multiplier greater than ten would often require extraordinarily high drawbar pull capabilities that most standard tractors do not possess, leading to inefficiency or risk of damage. Thus, the accepted standard and practice is to adhere closely to this tenfold ratio for safe and effective towing of aircraft in operational scenarios.
