E6B Basic Flight Computer

This Chrome extension solves wind triangle problems by letting you enter four of six values (three speeds and three angles) and calculating the remaining two. It then demonstrates the solution with an animated E6B-style flight computer: the disk rotates, parts slide, and marks appear to guide each step.

You can input data with the keyboard or by using the ++/-- buttons to adjust values, and you can press and hold to continuously change a value. The interface adapts to device orientation and supports zoom and pan for easier data entry. The app starts in your Windows language if it is English, French, German, Spanish or Dutch; otherwise English. It is the free version of the Animated Flight Computer app, offering essential wind-triangle solving and explanatory tabs.
