The Fuel Metering Unit (FMU) is a critical component of the fuel system in aircraft engines,

ensuring that the engines receive the right amount of fuel at all times.

It regulates the fuel supply by controlling the fuel pump and monitoring various

parameters to maintain the desired fuel-air mixture ratio. 

The FMU consists of a metering valve and a pressure regulator, which work together

to ensure optimal engine performance and fuel efficiency. It is designed to withstand

harsh operating conditions, including extreme temperatures and vibrations,

and is typically located close to the engines to reduce the risk of pressure loss or contamination.

Fuel Metering Units (FMU) deliver state-of-the-art fuel control functionality with

significantly higher reliability and lower lifecycle costs versus the competition.
