A radar system performs a plurality of horizontal scans; from the horizontal scans, the radar system identifies several cells. Based on the horizontal scans, the radar system produces a first vertical profile that is applied to the identified cells. The radar system performs one or more vertical scans of one of the identified cells to get measured reflectivity values in elevation. The measured reflectivity values are used to create a second vertical profile. The second vertical profile is used to refine the first vertical profile at the location of the identified cell and also to proximal weather. The data used to create the first and second vertical profiles can be combined into a data packet and stored within the radar or transmitted to a remote device. The remote device can reproduce a third vertical profile from the information in the data packet at any point.

Vertical situation display using cell-based architecture

An avionics computer system receives or calculates storm growth rate data, converts that data into a renderable format, and displays that data visually. The avionics computer system receives location and trajectory data, projects a future storm size/height based on the trajectory and growth rate, and determines if the storm is likely to intersect the trajectory when the aircraft is projected to reach the storm location. Certain threshold growth rates are associated with some artifice indicating the severity of the storm. The application of such artifice may be weighted according to the aircraft trajectory, estimated growth rate, and a projected proximity to the storm.

Enhanced human machine interface for storm growth rate

A system may include a display and a processor. The processor may be configured to: break down two-dimensional weather radar reflectivity data into cells, each cell of the cells having a maximum rainfall rate location and a geometric area; prioritize the cells based at least on each cell's proximity to the aircraft, each cell's intensity, each cell's growth rate, each cell's storm top altitude relative to the aircraft altitude, and/or a threat convective level of the cell to select a highest priority cell; and output, to the display, a highest priority azimuth slice vertical radar image of the two-dimensional weather radar reflectivity data as graphical data, the highest priority azimuth slice vertical radar image corresponding to an azimuth slice of the two-dimensional weather radar reflectivity data for the highest priority cell. The display may be configured to display the highest priority azimuth slice vertical radar image.

System and method to select and display prioritized azimuth slice vertical radar image

A system may include a display and a processor. The processor may be configured to: obtain aircraft data associated with an aircraft; obtain or generate storm top data, the storm top data including information associated with storm top altitudes and storm top locations; generate aircraft relative storm top data; generate an aircraft relative storm top image based at least on the aircraft relative storm top data, wherein the aircraft relative storm top image depicts a view of weather in front of the aircraft, wherein the aircraft relative storm top image conveys information associated with a difference between at least some of the storm top altitudes and an altitude of the aircraft; and output the aircraft relative storm top image as graphical data.

System and method to display aircraft relative storm top image

A system may include at least one display and at least one processor installed in an aircraft. The at least one processor may be communicatively coupled to the at least one display. The at least one processor may be configured to: obtain aircraft data associated with the aircraft; obtain an azimuth value associated with an azimuth; obtain radar data associated with at least one threat; generate a three-dimensional threat image based at least on the aircraft data, the azimuth value, and the radar data; and output the three-dimensional threat image as graphical data. The at least one display may be configured to display the three-dimensional threat image to a user. The three-dimensional threat image may depict a three-dimensional relationship between the aircraft and the at least one threat. The three-dimensional threat image may convey a range dimension, a lateral dimension extended perpendicularly from the azimuth, and a height dimension.
