The FADEC controls the ____ that regulates the fuel flow to the engines.

The FADEC controls the ____ that regulates the fuel flow to the engines.

• A. Fuel Regulation Valve
• B. Fuel Control Unit
• C. Engine Control Module
• D. Fuel Metering Unit (FMU)

Answer: (D)

The FADEC acts as the engine’s brain, deciding how much fuel the engine needs based on inputs like throttle position and engine speed. It does not directly open or close a fuel valve itself; instead, it commands the device that actually meters the fuel to the injectors. That device is the Fuel Metering Unit. The FMU receives the FADEC’s electrical commands and positions its metering valve to deliver the precise fuel quantity required, ensuring proper engine operation and performance. Other terms don’t fit because they describe different parts or generic concepts that aren’t the fuel metering assembly that FADEC drives.
