Weather provider WSI Corp. is now providing pilots with a broader range of weather products, both on the ground and in flight. The newest offering is WSI ProLink, a Web-based portal that presents a comprehensive picture of weather along a user-entered route; it will soon be upgraded to accept and process flight plans as well. The system augments WSI's FBO-based (WSI PilotbriefPro) and cockpit-based (WSI InFlight) products. Weather images are updated every five minutes. The service is currently used by more than 1200 corporate flight departments, in addition to numerous airlines.
