Abstract

Weather information recording systems and methods are operable to record information detected by airborne aircraft. An exemplary embodiment generates a trigger event corresponding to the presence of weather of interest, stores weather information collected by an aviation electronics system in a memory in response to generating the trigger event, and downloads the stored weather information to a remote memory.

Claims

1. A method for recording weather information for weather encountered by an airborne aircraft, the method comprising:

generating a trigger event corresponding to the presence of weather of interest having at least one characteristic greater than a threshold;

storing weather information collected by an aviation electronics system in a memory in response to generating the trigger event; and

downloading the stored weather information to a remote memory.

2. The method of claim 1, wherein generating the trigger event comprises:

receiving radar returns from weather in proximity to the airborne aircraft;

generating radar return intensity information based upon the received radar returns; and

comparing the generated radar return intensity information with a radar return intensity threshold,

wherein the weather information is stored in response to the radar return intensity information exceeding the radar return intensity threshold.

3. The method of claim 2, further comprising:

storing the radar return intensity information in a plurality of range bins, wherein each range bin uniquely corresponds to a unique location from the airborne aircraft; and

counting the number of range bins with radar return intensity information exceeding the radar return intensity threshold,

wherein the weather information is stored in response to the number of range bins with the radar return intensity information exceeding the radar return intensity threshold exceeding a predefined range bin threshold.

4. The method of claim 1, wherein generating the trigger event comprises:

determining at least one dimension of the weather; and

comparing the at least one dimension of the weather with a corresponding dimension threshold,

wherein the weather information is stored in response to the at least one dimension of the weather exceeding a weather dimension threshold.

5. The method of claim 4, wherein the at least one dimension of the weather comprises at least one selected from a group consisting of a width of the weather, a height of the weather, and a depth of the weather.

6. The method of claim 1, wherein generating the trigger event comprises:

determining at least one characteristic of the weather; and

comparing the at least one characteristic of the weather with a corresponding weather characteristic threshold,

wherein the weather information is stored in response to the at least one characteristic of the weather exceeding the weather characteristic threshold.

7. The method of claim 6, wherein the at least one characteristic of the weather comprises at least one selected from a group consisting of a presence of lightning, a presence of hail, and a presence of icing.

8. The method of claim 1, wherein generating the trigger event comprises:

sensing turbulence of the airborne aircraft; and

comparing the sensed turbulence with a corresponding turbulence threshold,

wherein the weather information is stored in response to the sensed turbulence exceeding the turbulence threshold.

9. The method of claim 1, wherein generating the trigger event comprises:

storing the weather information collected by the aviation electronics system in the memory for a predetermined time period before a time that the trigger event was received.

10. The method of claim 1, wherein generating the trigger event comprises:

storing the weather information collected by the aviation electronics system in the memory for a predetermined time period after a time that the trigger event has ended.

11. The method of claim 1, wherein the weather information is stored in response to receiving a manual trigger event from a crew of the airborne aircraft.

12. The method of claim 1, wherein downloading the stored weather information to a remote memory comprises:

storing the weather information on a portable memory; and

transferring the weather information from the portable memory to the remote memory.

13. The method of claim 1, wherein downloading the stored weather information to the remote memory comprises:

wirelessly transferring the weather information to the remote memory.

14. The method of claim 1, wherein downloading the stored weather information to the remote memory comprises:

transferring the weather information to the remote memory over a communication system,

wherein the communication system comprises at least one selected from a group consisting of a local area network (LAN), the Internet, or a public switched telephony system (PSTN).

15. A weather information collecting system on an aircraft, comprising:

at least one weather sensor;

a processing system communicatively coupled to the at least one weather sensor, the processing system configured to determine weather information based upon weather detected by the weather sensor; and

an onboard memory that stores the determined weather information in response to a trigger event generated in response to the weather information exceeding a predefined threshold.

16. The weather information collecting system of claim 15, wherein the at least one weather sensor comprises:

a weather radar system configured to detect radar returns from the weather,

wherein the processing system determines radar return intensity values based on the radar returns, and

wherein the determined radar return intensity values are stored in the onboard memory in response to at least one of the determined radar return intensity values exceeding a predefined radar return intensity value threshold.

17. The weather information collecting system of claim 15, wherein the at least one weather sensor comprises:

an inertial measurement unit (IMU) configured to detect an acceleration of the aircraft when airborne,

wherein the processing system determines an acceleration value based on the sensed acceleration, and

wherein the determined acceleration value is stored in the onboard memory in response to an acceleration value exceeding a predefined acceleration value threshold.

18. The weather information collecting system of claim 15, further comprising:

a data interface communicatively coupled to the memory and configured to transfer the weather information stored in the onboard memory to a remote memory.

19. A weather information collecting system on an aircraft, comprising:

means for generating a trigger event corresponding to the presence of weather of interest; and

means for storing weather information collected by an aviation electronics system in a memory in response to receiving the trigger event; and

means for downloading the stored weather information to a remote memory.

20. The weather information collecting system of claim 19, wherein generating the trigger event comprises:

means for receiving radar returns from weather in proximity to the airborne aircraft;

means for generating radar return intensity information based upon the received radar returns; and

means for comparing the generated radar return intensity information with a radar return intensity threshold,

wherein the weather information is stored in response to the radar return intensity information exceeding the radar return intensity threshold.
