What is the primary function of the Fuel Pump Metering Unit?

The primary function of the Fuel Pump Metering Unit is to control fuel flow and pressure. This component plays a crucial role in ensuring that the engine receives the correct amount of fuel at the appropriate pressure, which is essential for optimal engine performance and efficiency. By maintaining the proper flow and pressure, the unit helps in the precise delivery of fuel to the engine, thereby supporting the overall operation of the aircraft.

Additionally, it is important to understand the context of the other options. Storing fuel is typically the responsibility of fuel tanks, while managing fuel quality involves separate filtration and treatment systems designed to remove contaminants. Measuring fuel consumption relates to systems that monitor how much fuel is used during operation, often involving gauges or sensors, but this does not directly fall under the purpose of the Fuel Pump Metering Unit. Therefore, controlling fuel flow and pressure is the key function that distinguishes this unit’s role within the fuel system.
