Abstract: A weather radar and terrain map display system for aircraft with the terrain elevation and weather information displayed in an easy to read and comprehend presentation. The system includes an antenna for transmitting and receiving radar signals, a receiver for digitizing the reflected radar signals, and a computer for storing the signals and calculating the latitude and longitude coordinates of the locations from which the reflected radar signals were reflected, and for storing terrain elevation data. A display simultaneously shows a plan view image and vertical views of contoured terrain elevation data and the weather conditions found by the radar. The terrain and weather displays are superimposed over one another to enable quick and efficient location of critical terrain and weather conditions. The system can also calculate the latitude and longitude coordinates of the radar echoes without antenna stabilization.

Abstract: A weather radar and terrain map display system for aircraft with the terrain elevation and weather information displayed in an easy to read and quickly comprehendible presentation. The system includes an antenna for transmitting and receiving radar signals, a digitizer for digitizing the reflected radar signals, a means for storing the signals and calculating the latitude and longitude coordinates of the features from which the reflected radar signals were reflected, and for storing terrain elevation data. Flight modes are programmable to rapidly change a size of an alert region appropriate for the current flight mode. A display simultaneously shows a plan view image and vertical views of contoured terrain elevation data and the weather conditions found by the radar. The terrain and weather displays 15 are superimposed over one another to enable quick and efficient location of critical terrain and weather conditions.
