Abstract: A system and process for providing systematic, updated, weather information from the ground to the pilot of an aircraft are disclosed. A ground station receives and assimilates weather data for satellite broadcast as digital weather data that is received by an aircraft (while on the ground or while airborne) within the satellite coverage area, encoded by a flight processor, and shown on a display screen to the pilot in map-type depictions and alpha-numeric format tailored to the operational needs of the pilot. The flight processor provides near real-time automatic processing and comparison of surface weather observations with the applicable forecast in both text and map depictions. The display screen information is controlled by a control panel that permits the pilot to select the departure, destination, alternate and any arbitrary airport with this selection establishing the map boundaries and with the projected flight path marked thereon.
