Abstract

A system and method for determining and displaying an unknown weather due to receiving maximum radar attenuation compensation using a three-dimensional memory. The system and method may also determine whether the flight plan conflicts with an unknown weather zone. The user is alerted to an unknown weather zone and any flight plan conflict with an unknown zone. The user is alerted to the unknown weather zone using displays, sounds, or words that can be generated based on a determined hazard level.

Claims

1. A method comprising:

receiving one or more parameters;

determining a zone of unknown weather information based on the received parameters and weather radar return information stored in a three-dimensional memory; and

outputting an alert based on the determined zone.

2. The method of claim 1, wherein the alert is at least one of a visual alert, textual alert, or audio alert.

3. The method of claim 1, wherein outputting comprises displaying one or more display features corresponding to the zone of unknown weather information.

4. The method of claim 3, wherein displaying comprises displaying on at least one of a vertical situation display or a three-dimensional display.

5. The method of claim 3, further comprising:

determining a hazard level based on one or more parameters; and

determining at least one of color, outline thickness, flashing, fill content, shape, or size of the display features based on hazard level.

6. The method of claim 5, wherein the one or more display features comprises at least one of a shape, a bar, or an axis.

7. The method of claim 1, further comprising:

determining whether a flight plan conflicts with the zone of unknown weather; and

outputting an alert if the flight plan conflicts with the zone of unknown weather.

8. The method of claim 7, wherein the alert is at least one of a visual alert, textual alert, or audio alert.

9. The method of claim 7, wherein outputting comprises displaying one or more display features corresponding to the flight plan.

10. The method of claim 8, wherein displaying comprises displaying on at least one of a vertical situation display or a three-dimensional display.

11. The method of claim 9, further comprising:

determining a hazard level based on one or more parameters; and

determining at least one of color, outline thickness, fill content, shape, or size of the one or more display features based on the hazard level and whether the flight plan conflicts with the zone of unknown weather.

12. A system comprising:

memory configured to store weather radar return information;

one or more input devices configured to receive one or more parameters;

one or more output devices; and

a processor in signal communication with the memory, the one or more input devices, and the one or more output devices configured to determine one or more unknown weather zones and generate one or more alerts based on the one or more unknown weather zones.

wherein the processor is.

13. The system of claim 12, wherein the output device is at least one of a two-dimensional display, a three dimensional display, or a speaker.

14. The system of claim 12, wherein the processor is also configured to determine a hazard level based on at least one of the parameters, and the alert comprises a display feature generated based on at least one of the hazard level and the zone of unknown weather.

15. A system comprising:

means for storing three-dimensional weather radar information;

means for receiving one or more parameters;

means for determining one or more zones of unknown weather based on maximum attenuation being received; and

means for generating an alert based on the one or more zones of unknown weather.

16. The system of claim 15, wherein the alert comprises one or more display features.

17. The system of claim 16, further comprising:

means for calculating a hazard level based upon at least one aircraft parameter; and

means for defining the one or more display features with at least one of color, outline thickness, fill content, shape, or size of the display features based on hazard level.

18. The system of claim 17, further comprising means for displaying in three-dimensions.
