Breguet range equation

[¦bre·gā ¦rānj i‚kwā·zhən] (aerospace engineering) An equation for the range of an aircraft stating that the range is equal to K (PE/SFC)(L/D) ln (TOW/LW), where PE is propeller efficiency, SFC is specific fuel consumption, L/D is lift-to-drag ratio, TOW is takeoff weight, LW is landing weight, and K is a constant (equal to 375 if the range is expressed in miles and the specific fuel consumption is expressed in pounds per horsepower-hour).
