Plain English Meaning

How much fuel the engine is burning right now, measured per hour. The faster fuel is going into the engine, the more power it is making and the sooner the tanks will be empty.

Full Definition

The rate at which fuel is being delivered to the engine, typically expressed in pounds per hour (PPH) or gallons per hour (GPH). In turboprop and turbine engines it is a primary engine performance indication, displayed on a dedicated cockpit gauge and used alongside torque, ITT, and propeller RPM to monitor and set power.

Context Anchor

Seen on engine instruments and in turboprop power-setting discussions, especially when checking engine operation and fuel use.
