  2. WX-500 OVERVIEW • 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.

  3. 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.

  5. GNS-430 WEATHER PAGE • In the NAV page group, press MENU to change options: • Clear Storm Data • Strike Mode – Cell or Strike • View Mode – 120° or 360° • Self Test

  6. GNS-430 MAP PAGE • From the MAP page, press MENU to change options: • Clear Storm Data (can also be accomplished by pressing the CLR WX button on the panel) • Set Range – from the Setup Map menu

  7. STRIKE DATA DISPLAY • Lightning Symbol – latest strikes, less than one minute • Large + sign = more than one minute old • Small + sign = more than two minutes old • Strike data is no longer displayed after three minutes

  8. 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.
