FIELD: aviation engineering. SUBSTANCE: method involves shaping of course signal, correction of landing pattern cross track error signal, and generation of landing approach control parameter. Prior to do so, approach course line signals are computed by geographical coordinates on runway axis, glide-path signals are shaped, approach range and altitude signals are computed and stored as geographical coordinates. In addition, space coordinates of flying vehicle are computed by using signals coming from satellite radio navigation system, signals controlling vehicle approach to geographical axis of pre-computed approach range and altitude are computed. As soon as vehicle has approached landing heading line by signals from radio navigation system, geographical coordinates of landing heading line, and vehicle navigation data transmitters, signals specifying more accurately location of flying vehicle are shaped, vehicle position is corrected by using range and altitude signals, then landing pattern cross track error signal is corrected and approach control variable is generated. Device implementing this method has course and speed transmitters and control console. Additionally introduced in device are antenna assembly, receiver-processor subsystem, first storage unit, altitude transmitter, and calculator. Antenna assembly is connected via receiver-processor subsystem to first input of calculator; output buses of control console and first storage unit are connected to calculator second and third inputs, respectively; outputs of course, speed, and altitude transmitters are connected, respectively, to fourth through sixths inputs of calculator. First through fifth outputs of calculator buses are connected to switching unit of on-board computer. Device is also provided with second storage unit and display; output bus of the former is connected to seventh input of calculator and sixth input of the latter is connected to display. EFFECT: improved safety of landing; enlarged functional capabilities. |
