Abstract

Claims (50)

1 . A system comprising:

a weather radar configured to be installed onboard an own ship aircraft;

processing circuitry for the own ship aircraft having access to a storage device, the processing circuitry configured to:

receive, from multiple weather information sources, weather information related to weather along a planned flight path of the own ship aircraft, wherein the weather information comprise weather radar data, first data received from a flight information system broadcast (FIS-B) service, and second data received from an automatic dependent surveillance-broadcast (ADS-B) system;

fuse the received weather information based on confidence priorities of the weather radar data, first data, and second data;

automatically determine whether to adjust the planned flight path for the own ship aircraft based on the fused weather information;

in response to determining to adjust the planned flight path for the own ship aircraft, output, via a user interface, a depiction of an adjusted flight path to flight crew for the own ship aircraft; and

output, via the user interface, an indication to the flight crew of a weather information source upon which the adjusted flight path is based, wherein the weather information source comprises at least one of a fusion of two or more sources, the FIS-B service, the ADS-B system, satellite based weather information, or own ship weather sensors.

2 . The system of claim 1 , wherein the processing circuitry is further configured to:

convert the received first data and second data into a common interim data format; and

evaluate the received weather information based on the common interim data format.

3 . The system of claim 1 , wherein the multiple weather information sources further comprise sensors onboard the own ship aircraft, sensors comprising one or more of an outside temperature sensor, a turbulence sensor, a global positioning system (GPS), or a barometric air pressure sensor.

4 . The system of claim 1 , wherein the processing circuitry is further configured to:

receive, via the ADS-B system, a track for a second aircraft different from the own ship aircraft;

determine whether the track for the second aircraft is a deviation from an original track for the second aircraft; and

determine whether to adjust the planned flight path of the own ship aircraft based on the determined deviation for the second aircraft and the fused weather information that is showing weather conditions on the planned flight path.

5 . The system of claim 4 , wherein the second aircraft is located in a 3D region of airspace through which planned flight path passes.

6 . The system of claim 4 , wherein the second aircraft is on a same flight trajectory.

7 . The system of claim 4 , wherein the second aircraft is on a heading within 90 degrees of an opposite direction of an own ship aircraft heading.

8 . A method comprising:

receiving, by processing circuitry for an own ship aircraft, weather information from multiple weather information sources related to weather along a planned flight path of the own ship aircraft, wherein the weather information comprise weather radar data, first data received from a flight information system broadcast (FIS-B) service, and second data received from an automatic dependent surveillance-broadcast (ADS-B) system;

fuse the received weather information based on confidence priorities of the weather radar data, first data, and second data;

automatically determining whether to adjust the planned flight path of the own ship aircraft based on the fused weather information;

in response to determining to adjust the planned flight path for the own ship aircraft, outputting, via a user interface, a depiction of an adjusted flight path to flight crew for the own ship aircraft; and

output, via the user interface, an indication to the flight crew of an information source upon which the adjusted flight path is based, wherein the weather information source comprises at least one of a fusion of two or more sources, the FIS-B service, the ADS-B system, satellite based weather information, or own ship weather sensors.

9 . The method of claim 8 , further comprising:

converting, by the processing circuitry, the received first data and second data into a common interim data format; and

evaluating, by the processing circuitry, the received information based on the common interim data format.

10 . The method of claim 8 , wherein the multiple weather information sources further comprise sensors onboard the own ship aircraft, the sensors comprising: an outside temperature sensor, a turbulence sensor, global positioning system (GPS) or a barometric air pressure sensor.

11 . The method of claim 8 , further comprising:

receiving, via the ADS-B system, a track for a second aircraft different from the own ship aircraft;

determining whether the track for the second aircraft is a deviation from an original track for the second aircraft; and

determining whether to adjust the planned flight path for the own ship aircraft based on the determined deviation for the second aircraft and the fused weather information that is showing weather conditions on the planned flight path.

12 . The method of claim 11 , wherein the second aircraft is located in a 3D region of airspace through which the planned flight path passes.

13 . The method of claim 11 , wherein the second aircraft is on a same flight trajectory.

14 . The method of claim 11 , wherein the second aircraft is on a heading within 90 degrees of an opposite direction of an own ship aircraft heading.

15 . A system comprising:

a weather radar configured to be installed onboard an own ship aircraft;

processing circuitry for the own ship aircraft having access to a storage device, the processing circuitry configured to:

receive, from multiple sources, weather information related to a planned flight path of the own ship aircraft, wherein the weather information includes at least two or more of first weather data received from an onboard weather radar, second weather data received from a flight information system broadcast (FIS-B) service, and third weather data received from an automatic dependent surveillance-broadcast (ADS-B) system;

fuse the received weather information based on confidence priorities of the first weather data, the second weather data, and the third weather data;

determining, based on the fused weather information, weather condition present in the planned flight path;

receive, via the ADS-B system, a track for a second aircraft different from the own ship aircraft;

determine an amount of deviation between the track for the second aircraft and an original track for the second aircraft;

determine whether to adjust the planned flight path of the own ship aircraft based on the amount of deviation and the fused weather information; and

in response to determining to adjust the planned flight path for the own ship aircraft, output, via a user interface, a depiction of an adjusted flight path to flight crew for the own ship aircraft; and

output, via the user interface, an indication to the flight crew of the fused weather information upon which the adjusted flight path is based.

16 . The system of claim 15 , wherein the second aircraft is located in a 3D region of airspace through which the planned flight path passes.

17 . The system of claim 15 , wherein the second aircraft is on a same flight trajectory.

18 . The system of claim 15 , wherein the second aircraft is on a heading within 90 degrees of an opposite direction of an own ship aircraft heading.
