Abstract

A method of controlling airport traffic is provided. The method includes routing a plurality of aircraft towards a runway and selecting a runway approach vector for each of the plurality of aircraft. First approach legs of each runway approach vector are separated from each other by a distance.

First claim

What is claimed is:

1 . A method of controlling airport traffic, said method comprising:
routing a plurality of aircraft towards a runway; and selecting a runway approach vector for each of the plurality of aircraft, wherein first approach legs of each runway approach vector are separated from each other by a distance.

2 . The method in accordance with claim 1 , wherein selecting a runway approach vector comprises plotting the first approach legs of each runway approach vector at successively greater distances from the runway.

3 . The method in accordance with claim 2 further comprising plotting a turn-to-final leg for each of the first approach legs, wherein a size of each turn-to-final leg increases as the first approach legs are spaced at the successively greater distances from the runway.

4 . The method in accordance with claim 3 further comprising plotting a final approach leg for each turn-to-final leg thereby forming a plurality of final approach legs, wherein the plurality of final approach legs substantially overlap with each other.

5 . The method in accordance with claim 1 further comprising defining a plurality of flight parameters for each runway approach vector, the plurality of flight parameters including at least one of speed or altitude of the aircraft.

6 . The method in accordance with claim 1 further comprising monitoring a position of the plurality of aircraft to verify each of the plurality of aircraft are traveling along the selected runway approach vector.

7 . The method in accordance with claim 6 , wherein monitoring a position of the plurality of aircraft comprises determining whether the plurality of aircraft are traveling along the selected runway approach vectors before being maneuvered into a turn-to-final leg of each runway approach vector.

8 . A navigational control system for use in an aircraft, said navigational control system comprising:
an autopilot system; a receiver configured to receive a signal including runway approach flight plan data; and a controller in communication with said autopilot system and said receiver, said controller comprising a processor and a memory storing data including a plurality of runway approach vectors that each include first approach legs separated from each other by a distance, said controller configured to:
receive a selection of one of the plurality of runway approach vectors, the selection based on the runway approach flight plan data included in the signal; and
instruct said autopilot system to execute the selected runway approach vector.

9 . The system in accordance with claim 8 further comprising a user interface in communication with said controller, wherein said user interface facilitates manual input of the selection of one of the plurality of runway approach vectors.

10 . The system in accordance with claim 8 , wherein said memory stores flight parameters for each of the plurality of runway approach vectors, said controller further configured to instruct said autopilot system to execute the flight parameters corresponding with the selected runway approach vector.

11 . The system in accordance with claim 10 , wherein said memory stores flight parameters including at least one of speed or altitude of the aircraft along the plurality of runway approach vectors.

12 . The system in accordance with claim 8 , wherein said memory stores runway approach vector data including the first approach legs of each runway approach vector plotted at successively greater distances from the runway.

13 . The system in accordance with claim 12 , wherein said memory stores runway approach vector data including a turn-to-final leg plotted for each of the first approach legs, wherein a size of each turn-to-final leg increases as the downwind legs are spaced at the successively greater distances from the runway.

14 . An air traffic control system for use in routing a plurality of aircraft towards a runway, said system comprising:
a transmitter; and a controller in communication with said transmitter, said controller comprising a processor and a memory storing data including a plurality of runway approach vectors that each include first approach legs separated from each other by a distance, said controller configured to:
receive a selection of different runway approach vectors for each of the plurality of aircraft; and
instruct said transmitter to transmit a signal to each of the plurality of aircraft, wherein each signal includes the selected runway approach vectors.

15 . The system in accordance with claim 14 further comprising a user interface in communication with said controller, wherein said user interface facilitates selection of the different runway approach vectors by an air traffic controller.

16 . The system in accordance with claim 15 further comprising a visual display in communication with said controller, wherein said controller is further configured to display the plurality of runway approach vectors on the visual display for viewing by the air traffic controller.

17 . The system in accordance with claim 14 , wherein said controller is further configured to provide an alert if the plurality of aircraft deviate from the selected runway approach vectors.

18 . The system in accordance with claim 14 , wherein said memory stores runway approach vector data including the first approach legs of each runway approach vector plotted at successively greater distances from the runway.

19 . The system in accordance with claim 18 , wherein said memory stores runway approach vector data including a turn-to-final leg plotted for each of the first approach legs, wherein a size of each turn-to-final leg increases as the first approach legs are spaced at the successively greater distances from the runway.

20 . The system in accordance with claim 19 , wherein said memory stores runway approach vector data including each turn-to-final leg plotted with a substantially constant radius.
