- World_Area_Forecast_Center abstract "A World Area Forecast Centre (WAFC) is a meteorological centre that provides real-time meteorological information broadcasts for aviation purposes. These broadcasts are supervised by ICAO (International Civil Aviation Organisation) in order to fulfill requirements of the ICAO Annex 3 covering meteorological information which is necessary for flights. The role of the WAFCs is to provide meteorological messages with world-wide coverage for pilot briefing. They are usually part of the Pre-Flight Information Bulletin (PIB).WAFC provides various types of data, including OPMET information, T4 charts (which are currently obsolete but some portions are still distributed due to legacy reasons), and GRIB and BUFR charts - these are Wind and Temperature charts and SIGWX charts (Significant Weather Chart) for SWH (high levels) and SWM (medium levels).There are only two World Area Forecast Centres, each providing a backup for the other. These are the UK Met Office and Washington NOAA, working in duplicate so it would be possible to replace each other in a case of failure. Each of these two services operates its own satellite-based broadcast system to distribute data to airports all over the world. The UK Met Office is called SADIS (SAtellite DIstribution System) and mainly covers Europe, Asia, Indian Ocean and Africa. The U.S. NOAA broadcast system is ISCS (International Satellite Communications System) and mainly covers America and the Pacific Ocean.".
