Abstract

A display system for an aircraft is provided. The system includes a processing unit configured to receive weather information associated with a flight path of a flight plan and to generate display commands based on the weather information. The flight plan includes a first waypoint associated with a first altitude. The system further includes a display device coupled with the processing unit and configured to receive the display commands and to display symbology representing the weather information. The weather information includes first weather information for the first altitude and second weather information at a second altitude, different from the first altitude.

Claims

1. A display system for an aircraft, comprising:

a processing unit configured to receive weather information associated with a flight path of a flight plan and to generate display commands based on the weather information, wherein the flight plan includes a first waypoint associated with a first altitude; and

a display device coupled the processing unit and configured to receive the display commands and to display symbology representing the weather information, wherein the weather information includes first weather information for the first altitude and second weather information at a second altitude, different from the first altitude.

2. The display system of claim 1, wherein the flight path includes a vertical flight path to the first waypoint, and wherein the display device is configured to display a vertical situation display view that includes the first weather information for the first altitude and the second weather information for the second altitude.

3. The display system of claim 2, wherein the first weather information for the first altitude includes wind direction, wind speed, and temperature for the first altitude at the first waypoint and the second weather information for the second altitude includes wind direction, wind speed, and temperature for the second altitude at the first waypoint.

4. The display system of claim 3, further comprising a user interface coupled to the processing unit and configured to receive a selection of a position on the flight plan other than the first waypoint from a user, and wherein, in response to the selection, the display device displays third weather information for the second altitude at the position on the flight plan.

5. The display system of claim 1, further comprising a user interface coupled to the processing unit and configured to receive a selection of the first waypoint from a user.

6. The display system of claim 1, further comprising a user interface coupled to the processing unit and the display device, wherein the display device is configured to display a first menu with a plurality of altitude selections to a user and the user interface is configured to receive an altitude selection from the plurality of altitude selections on the first menu from the user.

7. The display system of claim 6, wherein the display device is configured to display a plurality of increment selections to the user on the first menu and the user interface is configured to receive an increment selection from the plurality of increment selections on the first menu from the user.

8. The display system of claim 1, wherein the symbology representing the weather information includes wind direction expressed as degrees relative to true North.

9. The display system of claim 1, wherein the symbology representing the weather information includes wind direction expressed as an arrow indicating a tail wind or a head wind relative to the aircraft.

10. The display system of claim 1, further comprising a communications unit coupled to the processing unit, the communications unit configured to selectively send a message requesting an altitude clearance to the second altitude.

11. The display system of claim 10, further comprising a user interface coupled to the processing unit, wherein the display device is configured to display menu with a message selection, such that, upon selection of the message selection, the communications unit sends the message requesting the altitude clearance to the second altitude.

12. The display system of claim 1, wherein the display device is configured to display a pop-up box with a wind correction angle and a track wind component of the second altitude.

13. The display system of claim 1, wherein the display device is configured to render the second weather information in a color that indicates a temporal validity.

14. A method for displaying weather information on an aircraft, comprising:

receiving a first user selection, via a user interface, of a first waypoint on a flight path of the aircraft;

displaying, on a display device, first weather information for the first waypoint at a first altitude; and

displaying, on the display device, second weather information for the first waypoint at a second altitude.

15. The method of claim 14, wherein the step of displaying, on the display device, the second weather information includes displaying wind direction, wind speed, and temperature at the second altitude.

16. The method of claim 14, further comprising a step of receiving a second user selection, via the user interface, the second altitude.

17. The method of claim 14, wherein the displaying, on the display device, the second weather information, includes displaying the second weather information on a vertical situation display view.

18. The method of claim 14, wherein the displaying, on the display device, the second weather information, includes displaying the second weather information on a lateral situation display view.

19. The method of claim 14, further comprising a step of sending, in response to a second user selection, a message requesting an altitude clearance to the second altitude.

20. A display system for an aircraft, comprising:

a processing unit configured to receive weather information associated with a flight path of a flight plan and to generate display commands based on the weather information, wherein the flight plan includes a first waypoint and wherein the weather information includes wind direction, wind speed, and temperature at each of a first altitude at the first waypoint and a second altitude at the first waypoint;

a user interface coupled to the processing unit and configured to select the first waypoint to selectively display the weather information; and

a display device coupled to the processing unit and configured to receive the display commands and to display symbology representing the weather information, wherein the display device includes a vertical situation display view including the wind direction, wind speed, and temperature at the first altitude at the first waypoint and the wind direction, wind speed, and temperature at the second altitude at the first waypoint.
