Abstract

Methods, systems, and computer-readable media described herein provide for the display of taxi route control point information in conjunction with an alphanumeric taxi route display in an aircraft. Taxi route data is received and compared with airport map information to determine any taxi route control points along the taxi route. Information associated with the taxi route control points is then collected and displayed on a display unit of the aircraft in conjunction with an alphanumeric display of the taxi route. The information associated with the taxi route control points may include ATC clearance information, runway and taxiway status information, runway orientation information, runway and taxiway traffic information, or taxi route information such as distance remaining to the taxi route control point.

Claims

1. A method for displaying taxi route control point information on a display unit of a vehicle, comprising:

receiving taxi route data;

upon receiving the taxi route data, utilizing airport map information to determine a taxi route control point along a taxi route described by the taxi route data;

collecting information associated with the taxi route control point; and

displaying the information associated with the taxi route control point in conjunction with an alphanumeric taxi route display on the display unit.

2. The method of claim 1, wherein collecting the information associated with the taxi route control point comprises receiving air traffic control (“

ATC”

) clearance information associated with the taxi route control point.

3. The method of claim 1, wherein collecting the information associated with the taxi route control point comprises receiving one or more of runway status information and taxiway status information associated with the taxi route control point.

4. The method of claim 1, further comprising periodically updating the display of the information associated with the taxi route control point as the vehicle progresses along the taxi route.

5. The method of claim 1, further comprising:

determining that the vehicle is approaching the taxi route control point while progressing along the taxi route; and

upon determining that the vehicle is approaching the taxi route control point, displaying the information associated with the taxi route control point in the alphanumeric taxi route display.

6. The method of claim 1, wherein receiving the taxi route data comprises receiving the taxi route data from at least one of previously stored taxi routes, ATC datalink, and manual pilot input.

7. The method of claim 2, wherein receiving the ATC clearance information comprises receiving the ATC clearance information from at least one of a predefined rule, ATC datalink, and manual pilot input.

8. The method of claim 3, wherein receiving one or more of the runway status information and the taxiway status information comprises receiving the runway status information and the taxiway status information from at least one of a predefined rule, ATC datalink, and manual pilot input.

9. The method of claim 3, wherein receiving one or more of the runway status information and the taxiway status information comprises:

receiving aircraft traffic information regarding aircraft operating in proximity to the vehicle;

upon receiving the aircraft traffic information, utilizing the airport map information to determine a position, a heading, and a speed of the aircraft in relation to a runway or a taxiway associated with the taxi route control point based on the aircraft traffic information; and

determining the runway status information or the taxiway status information based upon the position, the heading, and the speed of the aircraft in relation to the runway or the taxiway associated with the taxi route control point.

10. The method of claim 1, wherein the alphanumeric the information regarding the taxi route control point is displayed in conjunction with a graphical map display of the taxi route.

11. The method of claim 1, wherein the display unit comprises at least one of a multi-functional display unit, a control display unit, a dedicated display unit, a handheld display unit, an electronic flight bag, and a printer in a cockpit of an aircraft.

12. A system for displaying taxi route control point information for a vehicle operating at an airport, comprising:

a memory for storing a program containing computer-executable instructions for displaying taxi route control point information; and

a processing unit functionally coupled to the memory, the processing unit being responsive to the computer-executable instructions and operative to;

receive taxi route data,

upon receiving the taxi route data, utilize airport map information to determine a taxi route control point along the taxi route described by the taxi route data,

collect information associated with the taxi route control point, and

display the information associated with the taxi route control point in conjunction with an alphanumeric taxi route display on a display unit in the vehicle.

13. The system of claim 12, wherein collecting the information associated with the taxi route control point comprises receiving air traffic control (“

ATC”

) clearance information associated with the taxi route control point.

14. The system of claim 12, wherein collecting the information associated with the taxi route control point comprises receiving one or more of runway status information and taxiway status information associated with the taxi route control point associated with the taxi route control point.

15. The system of claim 12, wherein the processing unit is further operative to:

periodically determine a progress of the vehicle along the taxi route; and

update the display of the information associated with the taxi route control point based on the progress of the vehicle along the taxi route.

16. The system of claim 12, wherein the processing unit is further operative:

receive traffic information associated with aircraft operating in proximity to the vehicle;

upon receiving the traffic information, utilize the airport map information to determine a position, a heading, and a speed of the aircraft in relation to a runway or a taxiway associated with the taxi route control point based on the traffic information;

determine runway status information or taxiway status information associated with the taxi route control point based upon the position, the heading, and the speed of the aircraft in relation to the runway or the taxiway; and

display the runway status information or the taxiway status information with the information associated with the taxi route control point in the alphanumeric taxi route display.

17. A computer-readable medium containing computer-executable instructions that, when executed by a flight management computer of an aircraft, cause the flight management computer to:

receive taxi route data;

utilize airport map information describing an airport at which the aircraft is operating to determine a taxi route control point along a taxi route described by the taxi route data;

determine identifying information associated with the taxi route control point from the map information;

receive air traffic control (“

ATC”

) clearance information associated with the taxi route control point; and

display the identifying information and the ATC clearance information associated with the taxi route control point in conjunction with an alphanumeric taxi route display on a display unit of the aircraft.

18. The computer-readable medium of claim 17, containing further computer-executable instructions that cause the flight management computer to:

receive one or more of runway status information and taxiway status information associated with the taxi route control point; and

display the runway status information and taxiway status information with the identifying information and the ATC clearance information associated with the taxi route control point in the alphanumeric taxi route display.

19. The computer-readable medium of claim 17, wherein the display unit comprises at least one of a multi-functional display unit, a control display unit, a dedicated display unit, a handheld display unit, an electronic flight bag, and a printer in a cockpit of the aircraft.

20. The computer-readable medium of claim 17, wherein receiving the ATC clearance information comprises receiving the ATC clearance information from at least one of a predefined rule, ATC datalink, and manual pilot input.
