What is the role of warning lights in relation to fuel systems?

The role of warning lights in relation to fuel systems is crucial for ensuring safe aircraft operation. When a warning light indicates low fuel pressure or low fuel quantity, it alerts the pilot to potentially critical conditions that could affect engine performance or lead to fuel starvation.

Low fuel pressure might indicate that the fuel pump is not delivering enough fuel to the engine, which could lead to engine failure if not addressed promptly. Similarly, a low fuel quantity warning is essential, as it informs the crew that fuel levels are insufficient for safe operation, preventing unexpected fuel exhaustion mid-flight.

This system of alerts is designed to enhance situational awareness and promote timely interventions, which are vital in aviation safety. The other choices relate to different systems and parameters unrelated to fuel management. For example, engine temperature and oil pressure are monitored through separate mechanisms, and battery voltage is tracked independently to ensure electrical stability.
