This app solves a wind triangle by allowing you entering four values out of six (three speeds and three angles) and calculating the remaining two. It then explains how you get these results with a flight computer, by animating it. It rotates the disk, slides it and add marks. It also shows what value to use for each step towards the solution.
Contains "--", "-". "+" and "++" buttons to enter a value. Click them to decrease/increase a value. Keep the mouse pressed to keep decreasing/increasing a value. "--" decreases 5 times faster than "-" and "++" increases 5 times faster than "+".
