What does FMU stand for?

• A. Fuel Management Unit
• B. Flow Meter Unit
• C. Fuel Metering Unit
• D. Fuel Monitoring Unit

Answer: (C)

The meaning of FMU is Fuel Metering Unit. Its job is to regulate the amount of fuel delivered to the engine in response to the pilot’s thrust request and engine conditions. It sits in the engine fuel control loop and uses signals from the engine control (FADEC/ECU) to adjust a metering valve, controlling fuel flow so the engine gets the right amount for the requested thrust while maintaining safe limits. The other options describe measuring, monitoring, or managing fuel in a broader sense, but they don’t capture the function of actually controlling how much fuel reaches the engine.
