How does the fuel flow indicator display fuel flow in the EICAS?

The fuel flow indicator in the Engine Indication and Crew Alerting System (EICAS) displays fuel flow in pounds per hour. This choice is correct because the T-6B aircraft uses a system that measures fuel flow based on weight rather than volume.

Using pounds per hour as the measurement allows for a more precise understanding of fuel consumption, especially given that fuel density can vary with temperature and pressure. By displaying fuel flow in this way, pilots can better assess the efficiency of the engines and manage fuel reserves more effectively, which is critical for flight planning and operational safety.

In contrast, options that suggest fuel flow would be measured in gallons per minute or gallons per hour fail to account for the aircraft's operational context and the varying conditions that affect fuel density. Similarly, pounds per minute would not be practical for long-term fuel management during flight, as it does not provide a comprehensive view of consumption over an extended period.
