AIRCRAFT LANDING APPROACH AND SYSTEM TO THIS END Russian patent published in 2015 - IPC G01S13/93 

FIELD: aircraft engineering.

SUBSTANCE: approach landing comprises measurement of heading angles of microwave radio stations, measurement of flight altitude and descent to runway at design vertical speed. Aircraft generates decent glide path with allowance for range received from anti-collision system set (ANS). Code of individual identification to be identified aboard the aircraft for landing latitude received from onboard altimeters and initiated thereat as preset altitude mark. Crew holds the preset descent glide path by eliminating errors between preset and current flight altitude by preset altitude mark. Or, descent glide path is generated by the signal of error between preset and current glide path inclination angles. Said error signal is fed to aircraft onboard ACS. Dispatcher workstation receives data on flight range and altitude from surface ANS to generate descent glide path as preset height and different between preset and current aircraft altitude (and to display its at indicator). Dispatcher defines the vertical deflection of glide path from said difference. Microwave radio station data and range received from ground ANS-bearing finder and displayed on indicator allow the dispatcher to define displacement error to output control instruction in radio channel. Indicator is used to define the error between preset and current flight path. Aircraft landing system applies anti-collision system comprises microwave radio stations, microwave direction finder, command microwave radio station antenna, anti-collision system set (ANS), code of individual identification to be identified aircraft onboard hardware as preset landing data and computer of preset altitude and deflection therefrom. Indicator is connected by its inputs with outputs of ground anti-collision station in altitude channels, azimuth channels, range channels and with computer outputs of preset altitude and deflection therefrom as well as microwave heading finder output. Besides, said indicator is connected by its inputs with outputs of ground anti-collision station in range and measured altitude to aircraft channels of masters of temperature and air pressure near ground. Aircraft incorporates onboard microwave radio station and altimeters. ground anti-collision station installed aboard aircraft communicated with the latter additionally comprises decoder (loading code ID unit), landing code master, two computers of preset altitude and deflection from preset descent glide path, altimeter and air sensor of temperature near ground.

EFFECT: higher safety of landing.
