This is the professional version of Basic Flight Computer, containing an example generator, a wind triangle drawing function, convertors and calculators. Any (student) pilot can use it to prepare a theoretical exam and any pilot can use it to prepare a flight.

A wind triangle consists of three speeds and three angles. This app allows you entering four of those six values to calculate 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.

In addition to solving a problem, the app also produces examples for the 15 different combinations of 4 given values with 2 to calculate. Sometimes a generated example produces "impossible" values, such as triangles degenerating to a single line or data for which it is not possible to construct a triangle. This is deliberate to let you as a (student) pilot think about the data entered. You can adapt these data to see how to get a valid set to solve.

Instead of entering data, the app contains a "-" and "+" button for each value. Tap them to decrease/increase a value or keep your finger on them to keep decreasing/increasing a value.
