DUATS, or Direct User Access Terminal Service is a weather information and flight plan processing service contracted by the Federal Aviation Administration (FAA) for use by United States civil pilots and other authorized users. The DUAT Service is a telephone- and Internet-based system which allows the pilot to use a personal computer for access to a Federal Aviation Administration (FAA) database to obtain weather and aeronautical information and to file, amend, and cancel domestic IFR and VFR flight plans. The DUAT Service provides direct access to weather information via a National Airspace System (NAS) Data Interchange Network II (NADIN-II) interface to the Weather Message Switching Center Replacement (WMSCR) System and the Air traffic control (ATC) Facilities for filing flight plans. The pilot users can interface the DUAT Services via the FTS-2001 toll free telephone numbers or via an Internet Interface into the Contractor's Facility.
The current DUATS service contractor is Computer Sciences Corporation (CSC). The service may be accessed by direct dial (using a terminal emulator like HyperTerminal), and the Internet via Telnet or HTTP.
