Aviation Digital Data Service (ADDS)

Operational and Experimental Aviation Digital Data Service (ADDS)

Our work in aviation weather dissemination continues through participation in the FAA ADDS (Aviation Digital Data Service) and NNEW (NextGen Network Enabled Weather) Programs. The ADDS Program provides today's aviators with convenient web access to a variety of important aviation weather information. The NNEW Program is crafting a new weather data distribution infrastructure to meet the needs of the FAA's Next Generation (NextGen) Air Traffic Control System.

Experimental and Operational ADDS are web sites hosted at RAL and the NWS's Aviation Weather Center to provide 24 hour access to aviation weather information. As their names imply, Operational ADDS provides weather information that has received an official operational designation from the NWS and FAA, while Experimental ADDS presents aviation weather products that have progressed from research status to a provisional experimental status subject to further feedback and evaluation by aviators. The ADDS web sites handle a high volume of users who range from private pilots to military flight planners and include many of the major US airlines.
