What does the term "Fuel Flow" indicate in turbine engines?

The volume of fuel injected into the combustion chamber

The rate at which fuel is consumed by the engine

The term "Fuel Flow" in turbine engines refers to the rate at which fuel is consumed by the engine. This measurement is crucial for understanding the engine's performance characteristics, fuel efficiency, and overall operational management.

Monitoring fuel flow helps pilots and engineers ensure that the engine operates within its designed parameters, allowing for optimal performance and preventing issues related to fuel starvation or excess consumption. This metric is often measured in pounds per hour or liters per hour, providing a clear indication of how quickly the engine is using the fuel supplied to it.

Understanding fuel flow is essential for flight planning and route management, as it directly impacts range, endurance, and fuel reserves. Proper management of fuel flow allows for efficient operation, which is vital in commercial aviation for cost control and operational safety.
