DAFIF (/ ˈ d eɪ f ɪ f /) or the Digital Aeronautical Flight Information File is a comprehensive database of up-to-date aeronautical data, including information on airports, airways, airspaces, navigation data and other facts relevant to flying in the entire world, managed by the National Geospatial-Intelligence Agency (NGA) of the United States. Download instrument approach plates and flight planning publications online. NGA Publications – Aeronautical Division. Flight Data (DAFIF) – Updated DAFIF files; Flight Information Publications (FLIP) – FLIP ECN / PCN; FLIP Planning and Enroute Sups – AP, GP, FIH, etc.
The DAFIF archive has a DOC folder describing the format.Joe Sewell 16:29, 9 April 2014 (UTC) The DAFIF data is a big directory tree, with each directory containing one or more 'tab seperated value' text files. At a guess, most people would use a tool to read this data, so the way it is stored didn't really matter to them.
Skies of war free download. anybody think a FOIA request would be effective?Scientes.bonum.et.malum (talk) 09:03, 1 July 2008 (UTC)
FOIA requests are almost always denied for mapping products; I'm not sure what the exemption is. However thanks to some kind (or unaware) souls, DAFIF seems to regularly pop up on rogue sites and open directories if you Google intensively for them. The DAFIF AIRAC 1013 cycle (December 2010) is online right now, for example. Rolypolyman (talk) 06:59, 20 July 2012 (UTC)
Why is it considered 'complete'? There are places that have airfields (for example) that aren't in DAFIF.. — Preceding unsigned comment added by 150.101.115.205 (talk) 10:58, 11 September 2012 (UTC)

DAFIF (/ˈdeɪfɪf/) or the Digital Aeronautical Flight Information File is a comprehensive database of up-to-date aeronautical data, including information on airports, airways, airspaces, navigation data and other facts relevant to flying in the entire world, managed by the National Geospatial-Intelligence Agency (NGA) of the United States.
Withdrawal of public access[edit]
DAFIF was publicly available until October 2006 through the Internet, however it was closed to public access because 'increased numbers of foreign source providers are claiming intellectual property rights or are forewarning NGA that they intend to copyright their source'.[1] Currently only Federal and State government agencies, authorized government contractors and Department of Defense customers are able to access the DAFIF data.
At the time of the announcement, the NGA did not say who the 'foreign source providers' were. It was subsequently revealed that the Australian Government was behind the move. The Australian government-owned corporation Airservices Australia in September 2003 started charging for access to Australian data. Rather than exclude the Australian data, the NGA opted to stop making the data available to the public.[2]

USFIF[edit]
A product called USFIF (pronounced as yoos-fəf) or the United States Flight Information File which contains only data related to the United States was available on the NGA website until October 2007. NGA no longer hosts any aeronautical information on the publicly available website.
Replacement for Google Earth Data[edit]
Since the DAFIF data has ceased to be available to the public, new sources of the data have arrived, though none is (yet) a complete replacement:
There's a fascinating story and loads of atmosphere in this game and the new engine ensures that you can explore every nook and cranny of each of the game's wonderfully detailed worlds. As the follow up to one of the most highly praised adventure games of all time, The Longest Journey, Dreamfall promises to be everything that adventure gamers could want - with a few new surprises thrown in as well. Suppression fire, flanking maneuvers and reconnaissance are all just as important as your accuracy with your weapons and your speed on the draw. Brothers in Arms: Road to Hill 30 - PC. Best pc games of 2004.
- In Google Earth Format (KML) Google Earth 3D Airspace
- Started soon after the withdrawal of the DAFIF data, the OurAirports web site is a community effort to produce an open (Public Domain) database of airports and navigation aids—nightly CSV data dumps are available from the site. Since OurAirports is open source, there are a lot of duplicate airports in the system and the data is not necessarily accurate as an official source would be.
- OpenStreetMap holds information about many aerodromes, and can be downloaded through the Overpass service.
- In other open formats, publicly contributed data, the Worldwide Soaring Turnpoint Exchange: Airspace
