A method for realizing an aircraft wake encounter risk warning system in the whole airspace

Abstract

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.

Description

technical field [0001] The invention relates to traffic management in civil aviation, in particular to a method for realizing an aircraft wake encounter risk warning system in the entire airspace, which can provide necessary wake reminder and warning functions for air traffic automation management equipment and radar control simulation equipment. Background technique [0002] Wake turbulence is the counter-rotating vortex formed at the wingtip due to the pressure difference between the upper and lower surfaces of the wing during the flight of the aircraft. In order to prevent dangerous events such as roll, sharp pitch, altitude drop, and stall that may occur after the following aircraft encounters wake turbulence, the Civil Aviation Administration of China has formulated the minimum wake distance separation standard between the front and rear aircraft. [0003] The air traffic automation management system applicable to the traffic management department of my country's civil ...

AI Technical Summary

Problems solved by technology

The current automatic air traffic management system and radar control simulation training equipment do not provide aircraft wake modules, which cannot provide early warning and reminders of wake encounters to air traffic controllers. On the one hand, there are potential safety hazards, and on the other hand, air traffic is restricted The deployment potential of controllers to flight conflicts affects the performance of controllers' air traffic command skills
