Abstract

A method, computer program product and apparatus for locating aircraft with respect to airport runways and environs, generating a graphical display of the aircraft position, heading and ground speed information relative to the aircraft runways and environs, and annunciating situational awareness advisories as a function of aircraft information relative to the airport runways and environs.

Claims

1. An airport position situational awareness computer program residing on a computer usable storage medium, comprising:

means for receiving one or more signals representative of current aircraft position, orientation and ground speed information;

means for accessing stored runway survey information as a function of the current aircraft position information; and

means for indicating a current position of the current aircraft relative to selected runway survey information as a function of the current aircraft position and orientation information, including;

means for generating a graphical depiction of the selected runway survey information for display on a cockpit display device; and

means for generating a plot the current aircraft position, orientation and ground speed information relative to the graphical depiction of the selected runway survey information for display on the cockpit display device.

2. The computer program of claim 1, further comprising means for generating an RF broadcast containing the current aircraft position information.

3. The computer program of claim 2 wherein the means for generating an RF broadcast containing the current aircraft position information further comprises periodically generating the RF broadcast.

4. The computer program of claim 2 wherein the means for generating the RF broadcast further comprises generating an RF broadcast containing the current aircraft orientation information.

5. The computer program of claim 2 wherein the means for generating the RF broadcast further comprises generating an RF broadcast containing the current aircraft ground speed information.

6. The computer program of claim 2 further comprising means for receiving one or more RF broadcasts containing current position information of objects external to an aircraft receiving the one or more RF broadcasts.

7. The computer program of claim 6 further comprising means for generating a plot of the current position information of the external objects relative to the graphical depiction of the selected runway survey information for display on the cockpit display device.

8. The computer program of claim 7 wherein the code means for receiving one or more RF broadcasts containing current position information of the external objects further comprises means for receiving one or more RF broadcasts containing current orientation information of the external objects.

9. The computer program of claim 8 wherein the code means for generating a plot the current position information of the external objects relative to the graphical depiction of the selected runway survey information for display on the cockpit display device further comprises means for generating a plot the current orientation information of the external objects relative to the graphical depiction of the selected runway survey information.

10. The computer program of claim 8 further comprising program code means for predicting a potential conflict between the aircraft receiving the one or more RF broadcasts and one or more of the external objects.

11. The computer program of claim 10 wherein the means for predicting a potential conflict further comprises means for determining an intersection of a velocity vector of the aircraft receiving the one or more RF broadcasts and a velocity vector of one or more of the external objects.

12. The computer program of claim 10 further comprising means for generating a potential conflict condition advisory as a function of determining an intersection of a velocity vector of the aircraft receiving the one or more RF broadcasts and a velocity vector of one or more of the external objects.

13. The computer program of claim 12 further comprising means for determining a priority of the potential conflict condition advisory relative to other advisories and alerts.
