What is the purpose of the Direct User Access Terminal System (DUATS)?

• A. Provides current FAA weather and flight plan filing services to certified civil pilots via PC, modem, or telephone
• B. Provides navigation data via VOR signals
• C. Displays the age of the aircraft's airframe
• D. Measures differential pressure

Answer: (A)

Direct User Access Terminal System is a planning and weather briefing tool for pilots. It gives certified civil pilots access to current FAA weather information and lets them file flight plans electronically using a computer, modem, or telephone. This streamlines preflight planning and ensures pilots have up-to-date weather data and a filed flight plan for FAA coordination.

Other items don’t fit because they describe functions not related to this system: providing navigation data via VOR signals is about navigation equipment and signals, displaying the age of the aircraft’s airframe is maintenance/airworthiness information, and measuring differential pressure is part of the aircraft’s air data system.
