Cirrus Software for DUATS

Software and data file downloads are further down on this page.

DUATS is pleased to offer Cirrus for DUATS, the Windows gateway to the Direct User Access Terminal System. Cirrus will connect to DUATS via our free 1-800 number (1-800-767-9989) and via the Internet.

This software allows you to request most DUATS functions off-line using an intuitive graphic interface. After you decide on what you need for your flight, all you need to do is click on the "Dial" button (for the 1-800 number) or the "Connect" button (for the Internet) and Cirrus downloads the requested information without further user intervention. You may immediately review the information in a window within Cirrus or recall it later from file(s) saved to your disk.

Cirrus lets you view your route of flight graphically with its extensive database of airports and navigational aids by pointing and clicking on a map. You can use the DUATS automated flight planner to rapidly plan your flight. Cirrus can obtain from DUATS a full weather briefing for your selected route of flight, or for specified areas.

Additionally, by downloading graphic weather maps you may see at-a-glance the weather on your route of flight.

Internet Connectivity Using Cirrus Version 5.0

You can now access all the functions of DUATS, including enhanced free Color Graphics, through an Internet Connection via your ISP. If you are connected to a Local Area Network (LAN) with Internet access, Cirrus will automatically connect. If you use a dial-up service to an Internet Service Provider (ISP) you must first make the dial-up connection.

DUATS Cirrus Version 5.0 will run on Microsoft Windows 95 and newer operating systems. If you are running Microsoft Windows 3.1 or Windows 3.11, you must use Cirrus 2.2. There are no plans to offer a Macintosh version of Cirrus.
