    Take off distance can be given as \[S_{LO}=\frac{1.44W^{2}}{g \rho_{\infty}SC_{L,max}T}\]Take-off distance is directly proportional to the square of weight of the aircraft therefore if the weight is increased by \(30 \%\) take off distance will also increase to \(1.69\) that is approximately \(70\%\).
