I am prepping for cross-country and beginning to think everything would be easier if wind didn’t exist. When you’re planning your route, you have to constantly correct for wind. And this involves something called the wind correction angle. It is the difference between the magnetic course you want to fly, and the magnetic heading you actually fly. In order to stay on course to a point, you need to compensate for the effects of the win, and steer the nose of the airplane into the wind. We use our E6B flight computer to find the effect of the wind in regard to ;
Groundspeed (rate of airplane’s progress over the ground)
Airspeed (rate of airplanes progress through the air)
Drift angle (angle between course heading and track)
Heading (the direction in which the nose of the airplane is headed)
Course (the intended path of the airplane over the ground).
Using the wind correction angle and your E6B flight computer, you can convert your true course to your true heading, and also find out what your ground speed will be for your flight. So again in summary, the difference between the magnetic course and the magnetic heading is the wind correction angle.
