Implementation method of warning system for situation when airplanes in whole airspace encounter wake vortexes

The invention discloses an implementation method of a warning system for a situation when airplanes in a whole airspace encounter wake vortexes. The system involves actual distance display of the airplanes, an alarm of the wake vortexes entering five sides, a five-sided wake vortex interval alarm and a whole airspace wake vortex interval alarm. When the airplanes encounter the wake vortexes on thefive sides or in the whole airspace, the airplanes are displayed in a signboard number mode; several colored transverse lines are adopted for representing the last airplane on the five sides; the front airplane which enters the five sides and is not in a runway is displayed in three modes, wherein the three modes include a colored wake vortex interval alarming line behind the front airplane, a forward extension type alarming cone and a rearward extension type warning cone; the whole airspace wake vortex interval alarm is displayed in two levels including a reminding level and an alarming level. By adopting the method, a controller can more visibly check the influence and change trend of the wake vortexes of the airplanes, not only can the occurrence rate of wake vortex encounter events ina terminal area be effectively reduced by about 5%, but also the launching and landing frequency of the airplanes on a frame in the terminal area per unit time can be increased by about 3%, and the operational safety and efficiency of civil aviation air traffic control are improved.
