1.2 FUNCTIONAL DESCRIPTION

The WX-950 is a TSO certified thunderstorm mapping system designed for airborne use. The system maps
electrical discharge activity 360 degrees around the aircraft to a distance of 200 nautical miles. Figure 1-1
is a simplified functional diagram that shows how the components are connected to each other and to other
aircraft systems.
Figure 1-1. System Functional Diagram
The WX-950 is a passive system that listens for electromagnetic signals with a receiving antenna. The
antenna detects intra-cloud, inter-cloud, or cloud-to-ground electrical discharges within a 200-nmi radius of
the aircraft and sends the resulting " discharge signals" to the display/processor. The processor digitizes,
analyzes, and converts the discharge signals into range and bearing data. This information is stored in the
storm buffer. The display shows discharges as cell or strikes depending on the display mode selected.
To maintain proper storm display orientation during turns, the WX-950 can be connected to an external
heading source. The heading source may be synchro XYZ or stepper (King KCS55) format.
