• The WX-500 Stormscope detects electrical discharges from thunderstorms within a 200 NM radius of the aircraft.
• Output is displayed on the Garmin GNS 430 MFD. GNS 430 provides complete control of WX-500 operating modes.
• Antenna detects intra-cloud, inter-cloud and cloud-to-ground discharges. Detects thunderstorms in all phases of development.
• Strike rate helps determine if storms are developing or dissipating.
• Works anywhere – on the ground or in the air. Check it before takeoff.
WX-500 OVERVIEW
ANATOMY OF A THUNDERSTORM
• A thunderstorm can build, mature and dissipate in as little as 20 min.
• Only a small percentage of lightning strikes occur between clouds and ground. Most are intra or inter-cloud.
• The WX-500 detects storms in all stages of development, and unlike weather radar can see the “storm behind the storm”.
There is a strong correlation between electrical discharge and convective wind shear.

THINGS TO REMEMBER!
• Never use the Stormscope to attempt to penetrate a thunderstorm. Avoid thunderstorms by at least 20 NM.
• Clusters of two or more discharge points indicate a thunderstorm. Avoid the clusters and you will avoid the thunderstorms.
• In the CELL display even a single discharge point may represent a thunderstorm and should be avoided.
