Why is it important to monitor fuel system pressures?

Monitoring fuel system pressures is crucial for ensuring proper fuel distribution and system functionality. Fuel pressure directly affects how effectively fuel is delivered to the engine. Too low of a pressure can lead to inadequate fuel flow, potentially causing the engine to run lean, which can result in poor performance or even engine failure. On the other hand, excessive pressure can lead to fuel system leaks or component failures.

By keeping a close eye on fuel pressures, pilots and maintenance personnel can verify that the fuel system is functioning within its design parameters, ensuring that the engine receives the right amount of fuel at the right times. This includes facilitating the proper atomization of fuel for combustion, which is vital for optimal engine performance and efficiency. Therefore, consistent monitoring helps in early detection of issues that could otherwise compromise safety and aircraft performance.
