How to Calculate Cruise Weight Fraction for Prop-Driven Aircraft?
Cruise Weight Fraction for Prop-Driven Aircraft calculator uses Cruise Weight Fraction = exp((Range of aircraft*(-1)*Specific Fuel Consumption)/(Maximum Lift to Drag Ratio*Propeller Efficiency)) to calculate the Cruise Weight Fraction, The Cruise Weight Fraction for Prop-Driven Aircraft is a measure of the proportion of an aircraft's weight that remains during the cruise phase of flight, typically compared to the maximum takeoff weight (MTOW), it indicates how much weight the aircraft has shed during the climb phase and how much fuel has been consumed by the time it reaches its cruise altitude and airspeed. Cruise Weight Fraction is denoted by FWcruise symbol.
How to calculate Cruise Weight Fraction for Prop-Driven Aircraft using this online calculator? To use this online calculator for Cruise Weight Fraction for Prop-Driven Aircraft, enter Range of aircraft (R), Specific Fuel Consumption (c), Maximum Lift to Drag Ratio (LDmaxratio) & Propeller Efficiency (η) and hit the calculate button. Here is how the Cruise Weight Fraction for Prop-Driven Aircraft calculation can be explained with given input values -> 0.958325 = exp((7126*(-1)*0.000166666666666667)/(5.081*0.93)).
