What must be monitored to avoid problems during braking?

Monitoring brake temperature indicators is essential during braking to avoid problems such as brake fade, which can occur when brakes overheat. Overheating can lead to reduced braking performance and could potentially compromise the safety of the aircraft during landing or in emergency situations. High brake temperatures can affect different components of the braking system, making it critical for pilots to keep an eye on these indicators, particularly during high-energy landings or multiple landings in quick succession. By closely monitoring the brake temperature, pilots can make informed decisions about the safety and effectiveness of their braking action, ensuring that the brakes do not reach critical temperatures that could result in failure or reduced effectiveness.

In contrast, while altitude, fuel quantity, and air speed are important parameters to monitor for overall flight safety, they do not directly relate to the braking system’s performance and potential issues associated with it. Therefore, concentrating on brake temperature indicators is key to maintaining safe and effective braking operations.
