THE E6-B FLIGHT CALCULATOR is the iconic tool of every aviator. Although eclipsed by electronic replacements, mastering the old analog "slide rule" is still a rite of passage during primary training. In the sub-menus to the left are links to two Flash E6-B Emulators. To move the indexes, click and hold, then spin or slide, or use left/right/up/down arrows on keyboard. To place a dot on the wind index, click on desired location.

And here is a link to a digital E6-B emulator, for the digitally minded amongst us:  http://www.csgnetwork.com/e6bcalc.html
