description abstract	A method is presented for predicting from basic airplane characteristics the elevator deflection required to maintain optimum landing attitude. Charts for evaluating the components of the equation for the elevator deflection required to land, as well as a comparison of computed and measured values for 15 airplanes, are included. This comparison of experimental and computed results shows that, for preliminary design purposes, the elevator deflection required to land can be satisfactorily predicted from the basic airplane dimensions. Because of variations in piloting technique, the computed deflection is considered as the minimum value required to maintain landing attitude. A simplified method of obtaining the down-wash angle near the ground and a limited analysis of the effect of flap type and deflection on the aerodynamic-center location and pitching-moment coefficient are presented as appendixes.
