For the past five years, Sferics technology has taken a backseat to datalinked weather as a means of skirting convective weather. But Avidyne hopes to change that with the introduction of a new state-of-the-art lightning detector system called TWX670. Like Stormscope and Strike Finder technology, it detects and plots distant lightning strikes, but unlike earlier equipment, it paints strikes in cell-like patterns color-coded by threat level. AVweb's Paul Bertorelli talked to Tom Harper from Avidyne about this new product.
