A Look Inside WSI Weather

Youve seen and almost certainly used a WSI Pilotbrief weather station in your travels. Its almost a required ritual of flight: Stop by the screen and make a last check of the radar or TFRs while you finish your lukewarm coffee. As a pilot, do you care whos behind the weather information you see at the FBO or in the cockpit? The answer is largely, No. But there are some differences between what you get from a briefer, on the web or from the competing XM weather provided by Baron Services. What we found more interesting was what a weather service must do in collecting, distilling and delivering the weather in a format on which pilots can depend.
