What is measured by the fuel flow transmitter and displayed in pounds per hour?

The fuel flow transmitter specifically measures the amount of fuel consumed by the engine over a period of time. This measurement is crucial for assessing engine performance and efficiency and is displayed in pounds per hour. By providing real-time data on engine fuel consumption, pilots can make informed decisions regarding fuel management, flight planning, and operational efficiency. Understanding fuel flow is vital for ensuring the aircraft operates within safe limits and optimizing fuel usage during flight.

The options concerning inter-wing fuel transfer, refueling rate, and boost pump pressure do not directly relate to the continuous measurement of fuel being consumed by the engine, which is why they do not serve as the correct answer in this case. These factors are important operational aspects but are not the primary focus of what the fuel flow transmitter is designed to measure.
