METHOD FOR PREVENTING COLLISION OF AIRCRAFT DURING FLIGHT IN ZONES OF LOW DENSITY OF AIR TRAFFIC AND ABSENCE OF AIR CONTROL SUPPORT Russian patent published in 2017 - IPC G01S13/93 G08G5/04 

FIELD: radio engineering.

SUBSTANCE: relates to radio engineering methods of locating objects in air space and can be used to prevent collision of aircraft, in particular, light aerobatic aircraft having minimum instruments and positions in zones of low density of air traffic in absence of air control support. Said result is achieved due to that as per a measured value of distance to the aircraft, which is a danger for the flight, formed is a zone of air space, which is displayed on the air picture indicator in the form of circles with evenly arranged on them radial arrows, herewith the diameter of the displayed circle corresponds to the distance to the aircraft, which is a danger for the flight, the arrows length and direction are the speed and direction (approach/departure) of the aircraft subject to the risk of collision. As per the specified value of altitude interval between flight levels and the pressure difference of altitudes of the protected and the threatening aircraft on the air picture indicator displayed are the aircraft, for which the difference of altitudes or the estimated time to a dangerous approach exceeds a preset threshold. Depending on a degree of danger changed is the colour of displaying and audio signals are generated. When the threatening aircraft is in the coverage area and when the previously established value of dangerous approach distance is reached the pilot of the aircraft subject to the risk of collision communicates via the standard radio phone with the pilot of the threatening aircraft and matches the divergence maneuver.

EFFECT: technical result is generation of information for detecting by the pilot the presence of a potential danger of collision with another aircraft.
