AIR TRAFFIC CONTROL METHOD

WIPO Patent Application WO/2005/081201

A1

The invention relates to aviation. The inventive method consists in defining instantaneous information about co-ordinates of airplanes and the trajectory parameters thereof by means of a navigation satellite system and/or by means of data of the navigation systems of the airplanes. After receiving said information, the trend in the change of the flight parameters between every airplane and all the other airplanes is calculated. All airplanes located in the air traffic control region are divided into three groups by a computer complex according to a required control probability. Said probability is equal to zero for the first group, is greater than zero but less than one for the second group and is equal to one for the third group. The airplanes of said groups and information associated therewith are displayed on an indicator screen by different colours. The co-ordinates and trajectory parameters for the third group of airplanes are defined at intervals which are equal or greater than 2 seconds, for the second group of airplanes at intervals which are by two times greater than for the third group and for the first group at intervals which are by four times greater than for the third group. The flight information processing and display are carried out only for the airplanes which are located at a distance equal to or less than 250 km.
