DAFIF (//) 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
DAFIF was publicly available until October 2006 through the Internet, but 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'. 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 started charging for access to Australian data in September 2003. Rather than exclude the Australian data, the NGA opted to stop making the data available to the public.
The United States Flight Information File (USFIF; pronounced as yoos-fəf) contains only data related to the United States and was available on the NGA website until October 2007. NGA no longer hosts any aeronautical information on the publicly available website.
