Which of the following is NOT a factor in evaluating runway conditions?

In evaluating runway conditions, several factors play critical roles in ensuring the safety and effectiveness of takeoff and landing operations. Wind direction is important as it affects aircraft performance, stability, and how an aircraft handles during approach and departure. Surface conditions are vital to assess whether the runway is dry, wet, icy, or in any other state that could impact tire grip and braking efficiency.

Runway length is another essential factor, as it determines whether an aircraft has sufficient space to accelerate to takeoff speed or decelerate safely on landing. An aircraft's weight, speed, and type will all influence the required runway length for safe operations.

Average fuel consumption, while important for overall operational planning and efficiency of the flight, does not have a direct effect on evaluating runway conditions. Fuel consumption does not influence the physical state of the runway or the safety measures directly associated with its use. Thus, when considering factors crucial to runway evaluation, average fuel consumption stands apart from the others.
