Abstract

The present invention relates to a method for coupling a flight plan and a flight path using ADS-B information, and more specifically to a method for coupling a flight plan and a flight path, wherein a flight data processing unit of an air traffic control system or an arrival management system separately and directly receives ADS-B information such that the received ADS-B information can be used for coupling a flight plan and a flight path of an aircraft.

Claims

1. A method for coupling a flight plan and a flight path using automatic dependent surveillance-broadcast (ADS-B) information in an air traffic control system for controlling traffic of an aircraft by including a surveillance data processing unit providing a system track that is a data estimating a position and a speed of the aircraft, a flight data processing unit processing and managing data related to the flight plan, and a display unit providing a control screen to an air traffic controller, the method comprising:

a) receiving, by the surveillance data processing unit, radar information and the ADS-B information (ADS-B track or ADS-B plot) and fusing the two information to generate the system track;

b) receiving, by the flight data processing unit, the system track from the surveillance data processing unit and receiving the ADS-B information separately from the surveillance data processing unit to couple the flight path and the pre-stored flight plan; and

c) receiving, by the display unit, the system track and the flight plan to display a current flight state.

2. The method of claim 1, wherein step b) includes:

b-1) coupling the flight plan with a system track using the secondary surveillance radar (SSR) code of the system track (flight plan-system track), if the flight data processing unit receives the system track including the SSR code;

b-2) coupling the flight plan with the ADS-B track using the SSR code or Callsign of the ADS-B track (flight plan-ADS-B track), if the flight data processing unit receives the ADS-B track;

b-3) coupling the flight plan with the ADS-B plot using Callsign of the ADS-B plot (flight plan-ADS-B plot), if the flight data processing unit receives the ADS-B plot; and

b-4) periodically determining, by the flight data processing unit, whether there is the flight path (the system track, the ADS-B track, or the ADS-B plot including the SSR code) corresponding to the flight plan for each aircraft and maintaining the coupling between the flight plan and the flight path if there is the flight path matching the flight path of the steps b-1 to b-3.

3. The method of claim 1, wherein in step b), a criterion on which the flight data processing unit determines the number of aircrafts to be one is at least any one of a track number of the system track, a track number of the ADS-B track, the Callsign of the ADS-B plot or the ADS-B track, and 24-bit ICAO Address.

4. The method of claim 1, wherein in step c), the display unit receives the ADS-B information separately from the surveillance data processing unit and further includes the received ADS-B information in the system track and the flight plan to display the current flight state.

5. A method for coupling a flight plan and a flight path using ADS-B information in an arrival management system performing scheduling of aircrafts so that the aircrafts arrive at a certain point within a flight information region (FIR) at regular intervals, the method comprising:

1) receiving, by a surveillance data processing unit, radar information and the ADS-B information and fusing the two information to generate a system track;

2) receiving, by an arrival management system, the system track from the surveillance data processing unit and receiving the flight plan from the flight data processing unit;

3) receiving, by the arrival management system, the ADS-B information separately from the surveillance data processing unit and coupling the flight path including the received ADS-B information and the received system track with the received flight plan; and

4) generating the flight path of the aircraft using the coupled flight plan and flight path to schedule an arrival interval between the aircrafts.

6. The method of claim 5, wherein in step 3), the ADS-B information is received before an SSR code is issued and the Callsign included in the ADS-B information is used to couple between the flight plan and the flight path.
