How to Calculate Maximum Lift over Drag?
Maximum Lift over Drag calculator uses Maximum Lift to Drag ratio of Aircraft =
Landing Mass Fraction*
(((Aspect Ratio of a wing)/
(Aircraft wetted area/Reference Area))^(0.5))
to calculate the Maximum Lift to Drag ratio of Aircraft, The Maximum Lift over Drag formula directly and mainly the fuel and battery weight estimation. The Landing mass fraction varies wrt different aircraft types. Maximum Lift to Drag ratio of Aircraft is denoted by L/D_{max} symbol.
How to calculate Maximum Lift over Drag using this online calculator? To use this online calculator for Maximum Lift over Drag, enter Landing Mass Fraction (K_{LD}), Aspect Ratio of a wing (AR), Aircraft wetted area (S_{wet}) & Reference Area (S) and hit the calculate button. Here is how the Maximum Lift over Drag calculation can be explained with given input values -> 19.79899 =
