Stormscope

NOTE: Refer to the WX-500 Pilot's Guide for a detailed description of the
WX-500 StormScope.
The WX-500 StormScope Weather Mapping Sensor is a passive weather
avoidance system that detects electrical discharges associated with thunderstorms
within a 200 NM radius of the aircraft. The StormScope measures relative
bearing and distance of thunderstorm-related electrical activity and reports
the information to the display. Interfaces are currently only available for the
WX-500 StormScope System.
