The article describes the structure of the control system of unmanned aircraft and reflects currency and necessity of an automatic landing system for such type of aircraft. The main attention is paid to the research of the longitudinal channel of unmanned aircraft in the landing mode, that is to the variants of application in the control system of optimal Kalman filter (OKF) of conventional structure and with «freezed» coefficients. «Freezed» coefficients in this case are coefficients of a matrix of amendments, stored on the first second of continuous work of optimal Kalman filter. There are showed (submitted) the results of estimation of such nonmetering parameters as the angle and the speed of a wind at classical OKF, OKF with «freezed» coefficients and at the existence of additional gauges. On the base of the OKF estimations there was carried out the design of unmanned aircraft dynamics at the classical control law and at the presence of the estimation of the wind angle in the control law.
