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 step by step how you get a solution using an animated flight computer showing how to perform each step: the animation rotates the disk, slides it and add marks. It also shows which of the given values to use for each step towards the solution.

It also contains an example generator for the 15 different cases of 4 given values with 2 to calculate. Occasionally it also produces "impossible" values, such as triangles degenerated to a single line or data for which it is not possible to construct a wind triangle. This is deliberate to let a (student) pilot think about the data entered and find good data starting from there.

For each set of good data, it draws a wind triangle, giving you an insight in how to navigate. It illustrates this by showing a little plane flying along a course while compensating for the wind using a correct heading.

The conversions show you different units in SI and Imperial dimensions, while the calculators help you find cross wind components or help you preparing your flight.

Features
