Abstract

Systems and methods communicate sensor data pertaining to detected weather between aircraft. An exemplary system has at least one sensor on a transmitting aircraft, wherein the sensor is configured to detect weather and configured to output sensor data. The system has a first transceiver on the transmitting aircraft that is configured to transmit a signal with the sensor data. And the system has a second transceiver on a receiving aircraft that is configured to receive the signal containing the sensor data transmitted by the first transceiver. The sensor data of the transmitting aircraft is fused with sensor data of the receiving aircraft for a geographic region of interest to extend the effective sensor coverage and to resolve at least one of a location conflict and a severity conflict between the sensor data of the transmitting aircraft and the receiving aircraft.

4. The system of claim 3, wherein the meta data includes a time that the first sensor data was output by at least one sensor on the transmitting aircraft configured to detect weather, and wherein the processor system is further configured to:

determine an elapsed time corresponding to a difference between a current time and the time that the at least one sensor on the transmitting aircraft output the first sensor data; and

in response to the elapsed time being less than an elapsed time threshold, present the weather information corresponding to the first sensor data.

5. The system of claim 4, wherein the processor system is further configured to:

in response to the elapsed time being greater than the elapsed time threshold, present the weather information corresponding to the first sensor data with at least one of an icon color, an icon fill, or an icon intensity that is different from corresponding icons used to present current weather information.

6. The system of claim 3, wherein the meta data includes a location of the transmitting aircraft at the time the first sensor data was acquired, the receiving aircraft further comprises a display, and the processor system is communicatively coupled to the display and is further configured to:

determine at least one characteristic of the weather information;

determine a relative location of the weather information with respect to a current location of the receiving aircraft; and

present an icon indicating the determined characteristic of the weather information on the display, the icon presented at a location on the display corresponding to the relative location of the weather information.

7. The system of claim 1, wherein:

the processor system comprises a first processor system in the receiving aircraft, the first processor system configured to generate a query comprising a request for transmission of the first sensor data from the transmitting aircraft and a unique identifier of the transmitting aircraft, wherein the second transceiver transmits the query and the first transceiver receives the query; and
