Which factors significantly affect brake temperature?

• A. Altitude and surrounding weather
• B. Weight, pressure altitude, OAT, runway slope, and wind
• C. Throttle settings and fuel load
• D. Time of day and humidity levels

Answer: (B)

The correct choice highlights several critical factors that significantly influence brake temperature during aircraft operations. Weight directly affects the amount of kinetic energy that must be dissipated during braking; the heavier the aircraft, the greater the energy that needs to be managed. Pressure altitude contributes by altering air density, which can impact the effectiveness of brake cooling processes. Outside Air Temperature (OAT) also plays a role, as lower temperatures typically facilitate better heat dissipation from the brakes. Runway slope is another significant variable; when an aircraft is rolling downhill, it requires heavier braking force, leading to increased brake temperatures. Lastly, wind can impact the cooling effectiveness during landing and taxiing—headwinds can enhance cooling, while tailwinds can diminish it. These factors collectively create a scenario where proper management of brake temperature is crucial for safety and performance, marking their significance in evaluating brake temperature.
