Terminal Area Forecast
The Terminal Area Forecast (TAF) is the official FAA forecast of aviation activity for U.S. airports. It contains active airports in the National Plan of Integrated Airport Systems (NPIAS) including FAA towered airports, Federal contract towered airports, nonfederal towered airports, and non-towered airports. Forecasts are prepared for major users of the National Airspace System including air carrier, air taxi/commuter, general aviation, and military. The forecasts are prepared to meet the budget and planning needs of FAA and provide information for use by state and local authorities, the aviation industry, and the public.
A summary of the TAF forecast process is contained in the Forecast Process for 2014 TAF link. Starting with the 2013 TAF, forecasts of passenger enplanements and commercial operations at large, medium, and small hubs are based on origin and destination (O&D) models of passenger flow. The historical data and forecasts are located on an internet server and may be queried using the Query Data link. Users may create summary reports and user defined forecasts using the Detailed 2014 Model link. In addition the TAF databases may be downloaded in zipped dbf format through the Download 2014 Data link.
Once published the TAF remains constant until its next publication with the only exceptions being significant traffic shifts by major airlines or a significant data error. Any such change in an airport forecast will be noted below.
