CHAPTER 1
GENERAL INFORMATION
1.1 INTRODUCTION
This section contains a functional description of the Stormscope® model WX-950 Series II weather
mapping system, outlines the main features of the system, and provides a functional block diagram. The
basic WX-950 System (see table 1-1) consists of the following equipment:
•Display/Processor P/N 805-10950-001 (Black Bezel) or P/N 805-10950-002 (Gray Bezel)
•NY-163 Antenna P/N 805-10930-001 (White) or P/N 805-10930-002 (Black)
•Installation Kit P/N 817-10950-001
•Antenna Cable (ordered separately). Antenna cables, with the antenna connector pre-wired to
one end, are available in 6, 12, 25, 50 and 75 ft. lengths (see table 1-2). To meet different space
requirements the antenna connector can be ordered with either a straight or right-angle
backshell. Most installations will require the right-angle backshell.
Components supplied with the installation kit are identified in tables 1-3 and 1-4.

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.
