If I have Datalink weather, why would I need Stormscope?
Radar shows precipitation. Stormscope detects and maps lightning created by areas of strong updrafts/downdrafts. These two pieces of information are different and one does not duplicate the other. Lightning strikes occur in the developing or cumulus state of a thunderstorm – this is before falling precipitation exists to be mapped via Datalink WX. The initial stage of a thunderstorm contains many WX hazards that are dangerous to aircraft (strong vertical winds, severe turbulence, icing, convective wind sheer and lightning). The Stormscope locates these building thunderstorms by detecting the electrical discharges they always generate. Because the cumulus stage of a thunderstorm is usually precipitation free, it is rarely visible on the Datalink Nexrad image. The Stormscope is also a useful tool to enable you to determine if it is safe to fly through an area of rain showers. For example, you may consider flying through an area of heavy rain showers if no lightning is present. Finally, t
