Landing distance calculator by K.Prakashbalan

SL=1.69W2/ρ*g*S*CL max [T+D+μ(W-L)]

Where, SL – landing distance in meter, W-weight of a/c in newton, ρ-ambient density in kg/m^3,g-acceleration due to gravity in m/s^2,S-area in sq. meter, CL max-max lift coefficient, T – thrust in newton, D-drag in newton, μ-friction coefficient, L-lift in newton


(1)Sincreases with an increase in W/S

(2)SL decreases with an increase in CL max

(3)SL decreases with an increase in Trev/W

(4) SL increases with an decrease in ρ
