Calculating headwind or tailwind

E-6B Aluminum Flight Computer After receiving a query regarding headwind or tailwind calculation, Paul of Ask a has put together a short and very simple tutorial video showing the step by step process to perform the calculation. In the video tutorial, Paul demonstrates the calculation by using a mechanical flight computer, specifically the E-6B Aluminum Flight Computer which retails for only US$25 from Although the device looks complicated, it is actually fairly straightforward to use and the video focuses on using the wind side of the device which is used to find both the wind correction angle (WCA) and the aircraft ground speed.

The short tutorial is well worth watching – especially by student pilots just learning how to fly.
