摘要： A system including a radar receiver and a processor onboard an aircraft. The processor may be configured to: receive or generate weather radar data; identify an end user computing device to receive the weather radar data; determine whether the end user computing device has a high priority or low priority need for the weather radar data; reduce a size and/or an amount of the weather radar data to be a portion of the weather radar data; and upon a determination that the end user computing device has the low priority need for the weather radar data, route, via a datalink, the portion of the weather radar data having the reduced size and/or reduced amount of the weather radar data to the end user computing device.

摘要： A ground station is used by an air traffic controller to provide support to an aircraft. In particular, the ground station may mirror or regenerate a weather radar overlay of a flight display of the aircraft. The air traffic controller and the flight crew may then both see the same real-time weather information with minimum delay and achieve a similar level of situation awareness. The weather radar overlay may be displayed on a display of the ground station. The ground station may receive weather data and ADS-B data or other forms of location data and intended flight path from the aircraft via an air-to-ground communication channel. The weather data may be used to regenerate the weather radar overlay. The ground station may also use the ADS-B data to generate a coverage map of the aircraft in a selected airspace.

摘要： An aircraft hazard warning system or method can be utilized to determine a location of turbulence, hail or other hazard for an aircraft. The aircraft hazard warning system can utilize processing electronics coupled to an antenna. The processing electronics can determine an inferred presence of a weather condition in response to lightning sensor data, radar reflectivity data, turbulence data, geographic location data, vertical structure analysis data, and/or temperature data. The system can include a display for showing the weather condition and its location.

摘要： [Object] To appropriately evaluate reliability of a reception signal.
[Solving Means] A signal processing unit 20 includes a first integration unit 21, a Doppler detection unit 22, and a comparator circuit 28 as a reliability index calculation unit. The first integration unit 21 intermittently integrates a pulse train corresponding to a reception signal by using two systems and obtains two pieces of integrated data. The Doppler detection unit 22 divides each of the two pieces of integrated data into a plurality of range bins in time series, obtains a relationship between a frequency and intensity in each range bin for each of the two pieces of integrated data, and detects a Doppler shift amount from the relationship. The comparator circuit 28 calculates a reliability index of the reception signal by comparing the Doppler shift amounts (wind velocity values) of the two pieces of integrated data.-

摘要： A system including a radar receiver, a computer readable medium, and a processor. A data structure containing historical information pertaining to weather conditions for multiple locations may reside in the medium. The processor may be configured to: obtain aircraft data including information of an aircraft position; obtain external data; obtain a portion of the historical information pertaining to a location corresponding to the aircraft position; obtain weather radar data; analyze the weather radar data to determine if windshear exceeds a windshear alert threshold; upon an occurrence of the windshear exceeding the windshear alert threshold, determine whether to issue or suppress a windshear alert based on the aircraft data, the external data, and/or the portion of the historical information; and one of a) output the windshear alert for presentation to a user or b) adjust the windshear alert threshold causing the windshear alert to be suppressed and/or suppress the windshear alert.

摘要： 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.

摘要： This disclosure is directed to techniques for automated transmission of surveillance incident data or other anomalous incident data from an aircraft via a preferred transmission mode. An example method includes detecting, by a processing device onboard an aircraft, an anomalous incident involving the aircraft that qualifies for reporting relative to a set of anomalous incident reporting criteria. The method further includes identifying, by the processing device, data onboard the aircraft relevant to the anomalous incident. The method further includes detecting that the aircraft is in a status that makes available a selected data transmission mode for transmitting the data relevant to the anomalous incident. The method further includes communicating the data relevant to the anomalous incident to a transmission system for transmission from the aircraft via the selected data transmission mode in response to detecting that the aircraft is in the status that makes available the selected data transmission mode.

摘要： In some examples, a system is configured to determine a reliability index for weather information received by a weather system. The reliability index may indicate a degree of confidence of the accuracy of the weather information. For example, a system may determine a weather product for each of one or more voxels of a plurality of voxels in a three-dimensional or four-dimensional volumetric buffer, and based on a combination of the weather product and the weather information, determine a reliability index for the weather product. The system may display a first visual representation of the weather product and a second visual representation of the corresponding reliability index.
