Experimental Graphical Forecasts for Aviation
January 12, 2016 Leave a comment
The Aviation Weather Center has released new Experimental Graphical Forecasts for Aviation, described by the AWC:
The Experimental Graphical Forecasts for Aviation are designed to provide meteorological information equivalent to the textual Area Forecast (FA) in a graphical format, as requested by the FAA. This product includes observations and forecasts valid for the continental United States that provide data critical for aviation safety, overlaid on high-resolution basemaps. Please note that the text-based Area Forecast is still being produced.
A tutorial on the new forecast is available here.
As FAA noted in a recent draft revision to AC 00-45H, Aviation Weather Services:
The FA contains weather information in a format originally developed in the 1950s. By design, it carries a character count limitation and is prohibited from describing instrument flight rules (IFR) conditions over the CONUS and Hawaii (reserved for Airmen’s Meteorological Information (AIRMET) and significant meteorological information (SIGMET)).
While the FA met aviation weather information needs for many years, today the National Weather Service (NWS) provides equivalent information through a number of better alternatives. Plans are to discontinue the six FAs covering the CONUS and one FA covering Hawaii, which will then be replaced by digital and graphical products produced by the NWS. No near-term changes are planned for the FAs for Alaska, the Caribbean, or the Gulf of Mexico. (Appendix E)
