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.

System and method for turbulence detection

A method for indicating a weather threat to an aircraft is provided. The method includes inferring a weather threat to an aircraft and causing an image to be displayed on an aviation display in response to a determination by aircraft processing electronics that the inferred weather threat to the aircraft is greater than a measured weather threat to the aircraft.

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 turbulence 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 turbulence hazard and its location.

The hazard warning system that included processing system for detecting a high altitude ice crystal (HAIC) or HAIC cloud (HAIC) condition. The aircraft warning system can use an inferred detected process or a non-inferred detection process. Warnings of high altitude ice crystal conditions can allow an aircraft to avoid threats posed by HAIC or HAICconditions including damage to aircraft equipment and engines.

Weather radar system and method for detecting a high altitude crystal cloud condition

A hazard warning or weather radar system or method can be utilized to determine a location of ice. The system and method can be used in an aircraft. The aircraft weather radar system can include a radar antenna and an electronic processor. The radar antenna receives radar returns. The processor determines levels of icing conditions and causes the levels to be displayed on an electronic display.

System and method for ice detection

A hazard warning system can be utilized in an aircraft. The hazard warning system can include a processing system for determining a high altitude ice crystal (HAIC) condition and causing a warning of the HAIC condition to be displayed. An avionic display can be used to display the warning of the HAIC condition.

Weather radar system and method for high altitude crystal warning interface

The hazard warning system that included processing system for detecting a high altitude ice crystal (HAIC) condition. The aircraft warning system can use at least two types of radar returns to detect the HAIC condition. Warnings of high altitude ice crystal conditions can allow an aircraft to avoid threats posed by HAIC conditions including damage to aircraft equipment and engines.

Weather radar system and method for detecting a high altitude crystal condition using two or more types of radar signals

Methods, systems, and computer-readable media relating to providing weather data generated by a weather radar system of an aircraft are provided. The method includes receiving radar returns from at least one of a horizontal radar scan and a vertical radar scan. The method includes detecting a plurality of weather cells based on at least one of the horizontal radar scan and the vertical radar scan. The method includes providing display data representative of the plurality of weather cells. The method includes automatically providing updated display data representative of the plurality of weather cells based on at least one of an additional horizontal radar scan and an additional vertical radar scan.

A 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 turbulence 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 turbulence hazard and its location.

A hazard warning or weather radar system or method can be utilized to determine a location of ice. The system and method can be used in an aircraft. The aircraft weather radar system can include a radar antenna and a processor. The radar antenna receives radar returns. The processor can: 1. identify on a display a region of potential ice associated with a blow off region in response to the radar returns, temperature data, and wind data; 2. identify on a display a region of potential ice associated with a stratiform region in response to radar returns, temperature data, and a history of convective cells in the stratiform region; or 3. perform both 1 and 2.

A method for computing and displaying a weather hazard threat level for a weather radar system of an aircraft includes receiving weather radar returns from a radar antenna of the weather radar system. The weather radar returns include at least one of horizontal scans and vertical scans. Radar reflectivity may be determined from the weather radar returns, and, for at least one of the horizontal scan data and the vertical scan data, areas of radar reflectivity and a temperature associated with the areas of radar reflectivity may be determined. A lightning flash rate may be estimated using the radar reflectivity, areas of radar reflectivity, and temperature associated with the areas of radar reflectivity. Weather radar information may then be displayed, wherein the weather radar information is adjusted on the display based on the lightning flash rate.
