Abstract

A system and method for alerting when a trend vector associated with a traffic aircraft is predicted to intercept a travel route of an ownship aircraft. A control module receives real-time aircraft state data, flight plan data, and traffic data associated with the traffic aircraft. The control module processes these data and constructs the travel route of the ownship aircraft from the current location to the intended destination The control module generates the trend vector associated with the traffic aircraft, predicts a location of an intersection of the trend vector and the travel route, determines an amount of time it will take for the ownship aircraft to reach the location of the intersection, and generates display commands that cause the display device to generate an alert that visually distinguishes the location on the image based at least in part on the amount of time.

First claim

What is claimed is:

1. A system for alerting, in an ownship aircraft, when a trend vector associated with a traffic aircraft that is external to the ownship aircraft is predicted to intercept a travel route of the ownship aircraft, the system comprising:
a control module operationally coupled to receive real-time aircraft state data, flight plan data, and traffic data associated with the traffic aircraft, the real-time aircraft state data including a current location, a current heading, and a current speed of the ownship aircraft, the flight plan data including an intended destination of the ownship aircraft, the control module configured to:
process the real-time aircraft state data, the flight plan data, and the traffic data;
construct the travel route of the ownship aircraft from the current location to the intended destination;
generate display commands that cause a display device to render an image showing the ownship aircraft at the current location and at the current heading;
generate the trend vector associated with the traffic aircraft;
predict a location of an intersection of the trend vector and the travel route;
determine an amount of time it will take for the ownship aircraft, at the current location, the current heading, and the current speed, to reach the location of the intersection; and
generate display commands that cause the display device to generate an alert that visually distinguishes the location of the intersection on the image by rendering the location of the intersection in different colors depending on a type of alert and based at least in part on the amount of time.

2. The system of claim 1 , wherein the control module is further configured to:
process the traffic data to determine if the traffic aircraft is out of a field of view of the image; and
when the traffic aircraft is out of the field of view of the image, generate display commands that cause the display device to render the trend vector as a dotted line that extends from the location of the intersection toward the traffic aircraft.

3. The system of claim 1 , wherein the control module is further configured to:
conduct comparisons of the amount of time to a plurality of threshold time values; and
generate display commands that cause the display device to visually distinguish the alert based on the comparisons.

4. The system of claim 3 , wherein the control module is further configured to:
generate display commands that cause the display device to render the alert using the different colors based on the comparisons.

5. The system of claim 4 , wherein the plurality of threshold time values include a first threshold time value and a second threshold time value, the first threshold time value greater than the second threshold time value.

6. The system of claim 5 , wherein the control module is further configured to:
generate display commands that cause the display device to render the alert using a first color when the amount of time is less than the first threshold time value and greater than the second threshold time value; and
generate display commands that cause the display device to render the alert using a second color when the amount of time is less than the second threshold time value.

7. The system of claim 3 , wherein the control module is further configured to generate display commands that cause the display device to render the alert as a predefined size and shaped.

8. The system of claim 1 , further comprising:
a real-time aircraft state data source configured to supply the real-time aircraft state data;
a flight plan data source configured to supply the flight plan data; and
a traffic data source configured to supply the traffic data.

9. The system of claim 1 , wherein:
the control module is further operationally coupled to receive airport feature data, the airport feature data representative of an airport field; and
the control module is further configured to process the airport feature data and generate display commands that cause the display device to render the image showing the ownship aircraft at the current location and heading on the airport field.

10. The system of claim 9 , further comprising:
a real-time aircraft state data source configured to supply the real-time aircraft state data;
a flight plan data source configured to supply the flight plan data;
a traffic data source configured to supply the traffic data; and
an airport feature data source configured to supply the airport feature data.

11. The system of claim 1 , wherein the location of the intersection includes a discernable width and length of the intersection defining a discernable area of the intersection that is rendered in the different colors.

12. The system of claim 11 , wherein the area is a two-dimensional shape, a polygon, or a quadrilateral.

13. A system for alerting, in an ownship aircraft, when a trend vector associated with a traffic aircraft that is external to the ownship aircraft is predicted to intercept a travel route of the ownship aircraft, the system comprising:
a real-time aircraft state data source configured to supply real-time aircraft state data, the real-time aircraft state data including a current location, a current heading, and a current speed of the ownship aircraft;
a flight plan data source configured to supply flight plan data, the flight plan data including an intended destination of the ownship aircraft;
a traffic data source configured to supply traffic data associated with the traffic aircraft;
an airport feature data source configured to supply airport feature data, the airport feature data representative of an airport field; and
a control module operationally coupled to receive the real-time aircraft state data, the flight plan data, and the traffic data, the control module configured to:
process the real-time aircraft state data, the flight plan data, the traffic data, and the airport field data;
construct the travel route of the ownship aircraft from the current location to the intended destination;
generate display commands that cause a display device to render an image showing the ownship aircraft at the current location and at the current heading on the airport field;
generate the trend vector associated with the traffic aircraft;
predict a location of an intersection of the trend vector and the travel route;
determine if the traffic aircraft is out of a field of view of the image;
determine an amount of time it will take for the ownship aircraft, at the current location, the current heading, and the current speed, to reach the location of the intersection;
generate display commands that cause the display device to generate an alert that visually distinguishes the location of the intersection on the image by rendering the location of the intersection in different colors depending on a type of alert and based at least in part on the amount of time; and
