In the context of aircraft braking, what does 'fail-safe' refer to?

'Fail-safe' in the context of aircraft braking refers to a system's ability to detect and indicate failure conditions. This vital capability is designed to ensure that if a malfunction occurs within the braking system, pilots and maintenance crews can be alerted to the problem before it compromises safety. These warning systems often incorporate sensors and indicators that continuously monitor the performance and condition of the braking components.

By detecting failures early, the fail-safe system contributes to the overall safety of the aircraft, allowing for timely maintenance and ensuring that the aircraft can land safely. It emphasizes proactive measures in design to mitigate risks associated with failures, ensuring that the overall operation of the braking system remains secure.
