What is a "fuel flow meter"?

A fuel flow meter is a critical instrument in an aircraft's fuel system that measures the amount of fuel being delivered to the engine. It provides real-time data on fuel consumption, allowing pilots and engineers to monitor fuel efficiency and manage fuel load effectively. This measurement is vital for flight planning and operational safety, as it helps in calculating remaining fuel, optimizing fuel usage during flight, and ensuring that the engine receives the proper amount of fuel required for efficient operation.

The functionality of a fuel flow meter is essential for maintaining performance and ensuring that the aircraft operates within its fuel range. Understanding the volume of fuel being consumed assists in flight management decisions and safety protocols, making the accurate monitoring of fuel flow critical to both pilot operations and aircraft maintenance.
