Specific Fuel Consumption


Specific Fuel consumption (SFC) is a measure of the fuel efficiency of an aircraft's engine. It is defined as the amount of fuel consumed per unit of thrust produced by the engine. SFC is typically measured in pounds of fuel per hour per pound of thrust (lb/hr/lbf) or in grams of fuel per kilowatt hour (g/kWh). A lower SFC indicates a more fuel-efficient engine, which can result in lower operating costs and reduced environmental impact.
