Systems and methods for controlling a weather radar system are provided. A system for controlling a weather radar system includes a communications system including a transmitter-receiver and a processor. The transmitter-receiver is configured to receive first weather data from an external location. The first weather data includes a first weather condition, a location of the first weather condition, and a time of sensing the first weather condition. The processor includes a control module coupled with the communications system and configured to determine a point of interest based on the first weather data; acquire, by controlling an onboard weather radar system, second weather data at the point of interest; provide data representative of weather near the point of interest based at least in part on the second weather data; and transmit, by the transmitter-receiver, the data representative of weather near the point of interest to an external weather radar system.

A radar system includes an antenna. The radar system comprises a transmitter coupled to the antenna. The transmitter provides a radar signal. The radar signal includes a first set of pulses having a high bandwidth and a second set of pulses having a lower bandwidth. In one embodiment, the radar system is used for wind shear detection and the antenna is a smaller antenna.

A weather radar control system includes a processor configured to acquire first weather data for a first area extending from an aircraft from a weather radar system onboard the aircraft. The first weather data includes a first location of a weather event in the first area. The processor is further configured to receive second weather data for a second area with respect to the aircraft via the communication system from an external location where the second weather data includes a second location of a weather event in the second area, and correlate the first weather data and the second weather data. The processor is further configured to generate display data for display based on the correlated weather data where the display data is for a display area at least partially defined by the first and second areas, and provide the display data to a display system onboard the aircraft.

A hazard warning system can be utilized in an aircraft. The hazard warning system can include a processing system for determining an icing condition and causing an indication of the icing condition to be provided to an engine control, such as a full authority digital engine control (FADEC). The engine can be operated in a mode in response to the indication. The mode can be a lower efficiency mode.

A method of determining the ground speed or drift angle of an aircraft is described. It is determined whether or not a weather threshold has been met based on returns of a radar beam which is pulse compressed in a first scan. If the weather threshold is determined to have not been met, a ground speed or drift angle of the aircraft is determined based on Doppler processing of radar beam returns of a radar beam in a second scan. If the weather threshold has been met, a bottom radar beam is directed lower to the ground, and a ground speed or drift angle of the aircraft is determined based on Doppler processing returns of the bottom radar beam directed lower to the ground. A corresponding radar system is also described.

Systems and methods for displaying weather data relating to weather near an aircraft are provided. A method includes generating a three-dimensional weather profile of the weather near the aircraft based on reflectivity data from radar returns of a weather radar system of the aircraft. Generating the three-dimensional weather profile includes estimating weather data above a freezing layer height using a function that is based on a rate of reduction in reflectivity above the freezing layer. The method further includes transmitting weather display data to a display device, the weather display data being configured to cause the display device to display a visual representation of the three-dimensional weather profile.

A system and method for adjusting a target value for generating a vertical profile view in an aircraft weather radar system is provided. Processing electronics are configured to receive a target value for generating a vertical profile view of weather detected by the radar system. The processing electronics are also configured to adjust the target value to account for the motion of the aircraft and/or the motion of the detected weather.

A weather radar system for an aircraft is provided. The weather radar system includes processing electronics configured to process radar return data to identify a weather cell, to store information related to the identified weather cell in a database, to receive a selection of an identified weather cell from a user interface, to receive the information related to the selected weather cell from the database, and to cause the information to be displayed textually on a display in response to the received selection.

A method for indicating readiness of a predictive windshear system on an aircraft is provided. The method includes determining whether a windshear system is in a ready state and providing a first output that causes an indication of the ready state, the ready state being responsive to the windshear system being ready to detect a windshear event. Determining whether the windshear system is in the ready state includes comparing a first time until a first parameter reaches a first value with a second time for initialization of the windshear system and determining that the windshear system is ready to detect the windshear event in response to the first time being greater than the second time.

A method of providing convective weather data includes accessing lightning data, accessing statistical data representing a relationship between lightning flash rate data and at least one of reflectivity data and weather threat data, and accessing at least one of time of year data, geographic location data, temperature data, and altitude data. The method includes generating a lightning flash map based on the accessed lightning data, the accessed statistical data, and the at least one of time of year data, geographic location data, temperature data, and altitude data. The lightning flash map indicates at least one of reflectivity and a weather threat. The method provides the lightning flash map to an output port.
