Abstract

Systems and methods for collecting weather information for selected airspace regions are provided. In one embodiment, a method for collecting weather information for selected airspace regions comprises: receiving aircraft position information for a plurality of aircraft; forming an aircraft weather group based on flight path attributes derived from the aircraft position information; selecting at least a first representative aircraft from the weather group; and receiving at a weather information ground station, weather data from one or more representative aircraft of the aircraft weather group, wherein only the one or more representative aircraft transmit weather information to the weather information ground station from the aircraft weather group.

Claims

1. A method for collecting weather information for selected airspace regions, the method comprising:

receiving aircraft position information for a plurality of aircraft;

forming an aircraft weather group based on flight path attributes derived from the aircraft position information;

selecting one or more representative aircraft from the aircraft weather group; and

receiving, at a weather information ground station, weather data from the one or more representative aircraft of the aircraft weather group, wherein only the one or more representative aircraft transmit weather information to the weather information ground station from the aircraft weather group;

wherein the selecting the one or more representative aircraft further comprises;

broadcasting position information to the aircraft weather group, the position information comprising a position for each aircraft in the aircraft weather group and a position of the weather information ground station; and

wherein the one or more representative aircraft has selected itself as the one or more representative aircraft based on the position information broadcast to the aircraft weather group.

2. The method of claim 1, further comprising:

sending an affirmative weather transfer signal to at least a first representative aircraft of the one or more representative aircraft and a negative weather transfer signal to any aircraft of the weather group not selected as the first representative aircraft.

3. The method of claim 2, wherein the affirmative weather transfer signal includes one or both of:

a weather data transmission request to the first representative aircraft;

or

an indication of permission to the first representative aircraft to transfer current weather information at its own discretion.

4. The method of claim 1 wherein the selecting the one or more representative aircraft is either:

based on a random selection;

or

based on a relative position of aircraft within the aircraft weather group.

5. The method of claim 1, wherein the receiving the aircraft position information for the plurality of aircraft further comprises:

receiving Automatic Dependent Surveillance-Broadcast (ADS-B) messages from each of the plurality of aircraft.

6. The method of claim 1, wherein the forming the aircraft weather group based on the flight path attributes derived from the aircraft position information comprises:

selecting the aircraft weather group to include aircraft from the plurality of aircraft to include aircraft flying towards or through a weather area of interest.

7. The method of claim 1, wherein the flight path attributes include at least one of:

a direction of flight;

a radar detection direction;

an inter-aircraft distance;

an altitude; and

a position.

8. The method of claim 1, further comprising:

selecting a weather area of interest within an airspace; and

wherein the receiving, at the weather information ground station, the weather data from one or more representative aircraft of the aircraft weather group further comprises receiving weather conditions weather data regarding weather conditions within the weather area of interest.

9. The method of claim 8, wherein the selecting the weather area of interest further comprises one or both of:

selecting the weather area of interest based on current or predicted weather activity within the weather area of interest;

or

selecting the weather area of interest as part of a general weather survey of the airspace.

10. The method of claim 8, wherein the selecting the weather area of interest further comprises one or both of:

receiving an incoming request from a weather data network for airborne weather information for the weather area of interest;

or

selecting the weather area of interest based on weather activity detected by ground based weather sensors.

11. A system for collecting weather information for selected airspace regions, the system comprising:

at least one transceiver configured to communicate with aircraft via one or more data communication links;

a weather data processing system coupled to the at least one transceiver, the weather data processing system comprising a processor coupled to a memory that stores weather information compiled from aircraft collected weather data;

wherein the weather data processing system further comprises a weather area-of-interest identification function, an aircraft weather group selection function, and a representative aircraft nomination function;

wherein the aircraft weather group selection function is configured to receive, via the at least one transceiver, aircraft position information for a plurality of aircraft flying within an airspace and further configured to form an aircraft weather group from the plurality of aircraft based on a weather area of interest identified by the weather area-of-interest identification function and flight path attributes derived from the aircraft position information;

wherein the representative aircraft nomination function is configured to facilitate selection of one or more representative aircraft from the aircraft weather group;

wherein the weather data processing system is further configured to store the weather information regarding the weather area of interest in the memory; and

wherein the representative aircraft nomination function facilitates the selection of the one or more representative aircraft from the aircraft weather group by sending position information to the aircraft weather group, the position information comprising a position for each aircraft in the aircraft weather group and a position of a weather information ground station.

12. The system of claim 11, wherein the representative aircraft nomination function selects the one or more representative aircraft based on one of:

which aircraft of the aircraft weather group are closest to a center point of the aircraft weather group;

or

which aircraft of the aircraft weather group are closest to the weather information ground station.

13. The system of claim 11, wherein the representative aircraft nomination function selects the one or more representative aircraft;

and

wherein the weather data processing system sends an affirmative weather transfer signal to at least a first representative aircraft and a negative weather transfer signal to any aircraft of the weather group not selected as the first representative aircraft.

14. The system of claim 11, wherein the affirmative weather transfer signal includes one or both of:

a weather data transmission request to the first representative aircraft;

or

an indication of permission to the first representative aircraft to transfer current weather information at its own discretion.

15. The system of claim 11, wherein the aircraft weather group selection function is configured to derive the flight path attributes based on Automatic Dependent Surveillance-Broadcast (ADS-B) messages received from each of the plurality of aircraft.

16. The system of claim 15, wherein the flight path attributes include at least one of:

a direction of flight;

a radar detection direction;

an inter-aircraft distance;

an altitude; and

a position.

17. The system of claim 11, wherein the aircraft weather group selection function selects the aircraft weather group to include aircraft from the plurality of aircraft that are flying towards or through the weather area of interest.

18. The system of claim 11, wherein the weather area-of-interest identification function selects the weather area of interest based on current or predicted weather activity within the weather area of interest.
