Orlando, FL, October 07, 2003 - WSI Corp today announced the addition of three important data streams for WSI InFlight, its FAA certified cockpit weather datalink service. In a move designed to meet to corporate aviator's needs, WSI is adding Winds Aloft, Temperatures Aloft and Canadian weather information to its WSI InFlight aviation weather broadcast service.

Winds and Temperatures Aloft information will be available at 13 isobarometric levels ranging from 3,000 to 51,000 feet MSL. WSI will update the wind and temperature data every hour by running multiple wind forecast models and delivering the data to the cockpit every 5 minutes.

To address growing demand in international markets, WSI will also add three sets of Canadian weather information to the WSI InFlight service. Canadian information will include weather Doppler radar returns and METARs and TAFs.

WSI InFlight is designed to increase pilots' confidence in their enroute decision-making and to improve operational efficiency. "WSI InFlight's addition of Winds and Temperatures Aloft along with a full set of Canadian weather information gives professional aviators more robust in-flight awareness throughout North America" said Arlo Gambell, Director of Aviation Services. "Anticipated fuel savings that an operator of a turbine aircraft can achieve over just few flights will more than pay for the system and installation" continued Gambell.

Concurrently, WSI has announced an update to its WSI InFlight 3.0 Windows software client that incorporates the new information broadcasts for PC based displays. The software will also allow WSI InFlight customers using Electronic Flight Bags to be able to access reported and forecast conditions for airports by entering airport identifiers into a purpose built user interface. The software upgrade is free and can be downloaded from the WSI Internet site.
