PROCESSOR
This compact, tray-mounted computer processor receives electrical
discharge information from the antenna, processes it to determine
range and azimuth, processes the heading input, then forwards the
information for presentation on the MFD. The processor may be
installed almost anywhere in the aircraft.
ANTENNA
This combined crossed-loop and sense antenna is sealed in an
aerodynamic flat-pack and mounted on the outside of the aircraft
where it detects electrical discharges associated with thunderstorms.
Stormscope thunderstorm detection systems can correlate the
electric and magnetic signatures of lightning strikes better than
other systems due to their patented sense channel technology. The
antenna is designed to help filter out pulsed noise from sources other
than atmospheric electrical discharges.
FUNCTIONAL DESCRIPTION
Figure 1-2 and the following paragraphs describe how the major
components of the WX-500 connect to each other and to other aircraft
systems.
