What does a fuel leak detection system primarily monitor?

A fuel leak detection system is primarily designed to monitor fuel levels and pressure within the aircraft's fuel system. The primary function of this type of system is to identify any irregularities or changes that might indicate a leak. Monitoring fuel levels is crucial because a significant drop could signal that there is an unintended loss of fuel, potentially due to a leak. Similarly, observing fuel pressure is essential because a drop in pressure could also suggest leakage or flow issues, which could affect engine performance and safety.

Maintaining proper fuel levels and pressures is vital for efficient engine operation and overall system integrity. Any discrepancies detected by the system can prompt immediate investigation and corrective action, ensuring the safety of the aircraft during operation.
