## Breguet Range Equation Calculator

Just enter the required details in the corresponding fields of online Breguet range equation calculator to get the reliable result.

**Breguet Range Equation Formula:** For manual calculations, you could refer the below given formula.

**R = ( V / TSFC ) x ( L / D ) x ln ( Wi / Wf )**
R = Breguet Range

TSFC = Thrust Specific Fuel Combustion

V = Velocity

L / D = Lift to Drag Ratio

Wi = Initial Weight

Wf = Final Weight.
