weather information processor means within said aircraft for converting said weather information into specific weather map and pictorial depictions;
said weather information processor means including input output server means, coupled to said satellite communication receiver means and to a global positioning system receiver, said input output server means for receiving said weather information from said satellite communication receiver means and global position information from said global positioning system receiver;
mass memory means for storing at least said weather information and map information of said global region; and
color liquid crystal panel display means coupled to said weather information processor means for providing a display of graphical information, including a map of at least a portion of said global region and, simultaneously, a depiction of various weather information at the coordinate locations on said map prescribed in said weather information, and pilot selectable display functions;
said color liquid crystal panel display means including a touch responsive surface switching means for enabling pilot selection of individual functions for performance by said weather information processor means, including the function of outputting weather information to said color liquid crystal display means, wherein said touch responsive surface switching means comprises an overlay display of the individual functions including a plurality of icons associated with respective functions and graphically represented by said liquid crystal panel display means, and wherein said overlay display includes first icon means for selection of RADAR to provide radar mosaic images, second icon means for selection of the images of lightning;
third icon means for selection of weather conditions at a selected airport;
fourth icon means for selection of a code for the airport selected;
fifth icon means for showing previously received maps of weather data;
sixth icon means for display of a definition of the surface observation symbol displayed subsequent to selection of said third icon means;
seventh icon means for selecting an airport from a listing;
eighth icon means for displaying a smaller geographic region than the region on display; and
ninth icon means for displaying a larger geographic region than the region on display,said weather information processor means further including display control means for outputting display information to said color liquid crystal panel display means based upon the function associated with the icon touched by the pilot.

Abstract
Weather information, periodically collected from throughout a global region, is periodically assimilated and compiled at a central source and sent via a high speed data link to a satellite communication service, such as COMSAT. That communication service converts the compiled weather information to GSDB format, and transmits the GSDB encoded information to an orbiting broadcast satellite, INMARSAT, transmitting the information at a data rate of no less than 10.5 kilobits per second. The INMARSAT satellite receives that data over its P-channel and rebroadcasts the GDSB encoded weather information, in the microwave L-band, throughout the global region at a rate of no less than 10.5 KB/S. The transmission is received aboard an aircraft by means of an onboard SATCOM receiver and the output is furnished to a weather information processor. A touch sensitive liquid crystal panel display allows the pilot to select the weather function by touching a predefined icon overlain on the display'"'"'s surface and in response a color graphic display of the weather is displayed for the pilot.
