Determining Winds in Flight

Winds aloft forecasts are frequently in error. If you have an autopilot and some free time, you can calculate the actual winds at your location and altitude. It helps if you have GPS, too.

To solve an inflight wind problem you need your ground speed, true heading, true course, and true airspeed. Let’s assume your true course is 180°, your true heading is 160°, your last ground speed
