AIRCRAFT LANDING METHOD Russian patent published in 2009 - IPC B64D45/04 

FIELD: aircraft industry.

SUBSTANCE: invention refers to aircraft landing procedure, and is meant for being used in independent airborne systems of landing on runways which are not equipped with radio equipment, including level sections of roads and ground surface. At the runway deployment, there determined are geographical coordinates of two points on the longitudinal symmetry axis of the runway along its edges, and coordinates of those points are transmitted to the landing aircraft, where they are stored. Aboard the aircraft there determined are geographical aircraft position coordinates, northern and eastern speed components, heading, pitch angle, roll angle, flight altitude and vertical speed. Based on that data, runway heading angle, aircraft heading angle, glide slope angle and speed of change of those angles are computed on the board. Thus, signals of aircraft control in horizontal and vertical planes are generated. The effect is improving reliable and safe aircraft landing on the runway as well as improving efficiency of runway deployment thanks to simplified landing system.

EFFECT: possibility of aircraft landing is provided irrespective of aircraft distance to the runway and flight altitude, at any time of the year and day, and at any meteorological conditions, including at instrumental landing.
