Aircraft weather information system
First Claim
1. An aircraft-based weather information sharing and display system comprising:
- at a ground station;
reception equipment for receiving weather parameters from a plurality of weather-sensing sources;
processing equipment for generating a refined weather information report, based on said received weather parameters, using data compression techniques to reduce the size of said weather information report; and
transmission equipment for uplinking said refined data-compressed weather information report to a plurality of aircraft and at an aircraft;
standard weather information gathering equipment for detecting local weather parameters characterizing a weather condition in the vicinity of the aircraft;
transmission equipment for transmitting said local weather parameters to said ground station;
reception equipment for receiving said refined data-compressed weather information report uplinked by said ground station;
storage equipment for storing received said weather information report and said detected local weather parameters;
picture generating equipment for generating symbolic pictorial information based on the received refined weather information and said detected local weather parameters; and
weather information display equipment, coupled to the picture generating equipment, for displaying pictorial polygons indicating the dynamic behavior of said weather condition.

Abstract
A system and method that downlinks weather data, generated by existing weather and data sensors, to a groundstation. The groundstation utilizes data from multiple aircraft to form refined weather information, and uplinks the refined weather information to the aircraft. The refined weather information is stored at the aircraft and picture generating equipment, such as an existing on-board ground proximity terrain picture and symbol generator, generates pictorial information depicting the weather information. The pictorial information is displayed, for example by an existing EFIS or weather radar display, in the form of polygons.
