We find it rare to identify useable single storms from sferic (lightning radio signal) maps, with WWLLN or ENTLN sferic maps of regions in which the TGFs could have originated (i.e., within 800 km of the nadir of Fermi) for [+ or -] 10 min about the TGF times typically showing many clusters or clusters with large extents (see Figs.
If you've spent much time considering thunderstorm avoidance and the tools available, you've probably heard this before: Nexrad and sferics are strategic tools; airborne weather radar is tactical.
The average level of sferics activity differed between the experiments due to the annual rhythm of sferics activity, as thunderstorms are more common in the summer.
Use of sferics is worth its own article, but I will say that for this kind of matching up I prefer the more sensitive strike mode to cell mode.
Avidyne's two-piece (three with a display) tactical weather avoidance TWX670 system is the most modern sferics device to be had.
If there's a developing line of convective activity on the Datalink NEXRAD image, it's neither safe nor smart to assume that the area you plan to penetrating is free of activity, unless you can see with your eyes, onboard radar or sferics no cells have popped up or moved into since the last datalink update, or aren't heavy enough to show on NEXRAD.
First things first: Quality sferics gear displays most lightning activity in real time throughout the life cycle of a thunderstorm.
if and only if you have weather radar, a sferics device like a Storm-scope and/or datalinked Nexrad in the cockpit, plus weather flying experience and a solid-gold Plan B.
Traffic alerting, XM weather and sferics display cost extra but are available.
The G500 accepts oodles of remote inputs including the GDL69 XM receiver, a wide variety of traffic systems and the L-3 WX500 sferics. Garmin says it might work with Avidyne's TWX-series sferics.
Most owners tarted these airplanes up with all kinds of additional goodies, including traffic, dat-alink and sferics gear, so what used ones are out there are well equipped.
It consists of three separate weather sources--two satellite based and the third onboard sferics detection.
