            Documentation Program Operational


Effective Monday, September 12, 2011, at 1400 Coordinated Universal Time (UTC), the NWS Aviation Weather Center (AWC) in Kansas City, MO, will implement the Web-Enabled International Flight Folder Documentation Program (WebIFFDP) as an operational system. WebIFFDP will eventually replace the facsimile-based International Flight Folder Documentation Program (IFFDP).


Beginning September 12, 2011, WebIFFDP will be operationally available 24 hours a day, 7 days a week. Before using the service, authorized users must register by going to the following web address:


As a contracting state of the International Civil Aviation Organization (ICAO), the United States is obligated to provide flight documentation services to the international aviation community. Since October 1, 1998, in accordance with Chapter 9 of Annex 3 to the Convention on Civil Aviation, the AWC has provided the required meteorological information to airline operators and flight crew members for the purposes of dispatch planning, pre-flight briefing and en-route guidance as a facsimile-based system of distribution.


The new WebIFFDP system offers users a Qualified Internet Communications Provider (QICP) certified Website for obtaining international aviation weather information. QICP is an FAA certification that a Website meets specific security, availability and transaction-time standards. WebIFFDP also introduces users to an enhanced Web experience that includes custom virtual Flight Folders and other services not available through the current fax-based system.
