What is the function of the fuel flow transducer?

• A. It turns fuel flow into a digital signal and feeds it to the MAU and cockpit display.
• B. It heats the fuel.
• C. It filters the fuel.
• D. It meters air into the fuel system.

Answer: (A)

The fuel flow transducer measures how fast fuel is moving through a section of the line and turns that measurement into a digital electrical signal that the MAU uses and that can be shown on the cockpit display. This lets you see real-time fuel flow and use it for managing fuel consumption and engine performance. It doesn’t heat or filter the fuel or meter air into the fuel system—those functions are handled by other components.
