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.

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.
