Where is the fuel flow transmitter located in the fuel system?

• A. Between the fuel control and the fuel nozzles
• B. In the fuel tank
• C. In the cockpit
• D. Behind the pilot seat

Answer: (A)

The fuel flow transmitter is placed where it can measure the actual fuel going to the engine and send that information to the engine instruments. It needs to be in the line after the fuel control has metered the fuel but before it reaches the nozzles, so it can accurately sense the flow that will be delivered to the engine. That’s why it’s located between the fuel control and the fuel nozzles. Putting it in the fuel tank would only sense quantity rather than flow, and locations like the cockpit or behind the pilot seat aren’t in the actual fuel path.
