Put a dot. That is your starting point. Assume straight up is north. Draw a line at a 65 degree angle up to the right to represent your course and put a point at a distance to represent 150 KM. After one hour that is how far you flew due to engine power. Put a dot. Measure a line going 135 degrees down and to the left from that second dot distance on to scale to represent the 15 KM you would have been blown in one hour. You will have something that will look like the letter "V" on its side with the lowering a tenth the length of the upper leg. Put a third dot. Now measure the distances between the first dot and your third dot. That is the distance you flew in one hour and that is your ground speed. Complete the triangle. Measure the angle of that triangle down at your starting point. (Lets say it is about ten degrees.) That is the angle your plane needs to fly to compensate for the wind. You SUBTRACT it to the direction you want to go. So if you want to fly 65 degrees and the wind is blowing you 10 degrees off to the south, you are going to have to fly a course of 55 degrees to compensate for the wind. You fly 55 degrees, the wind blows you 10 degrees more to the south so you end up with a true heading of 65 degrees. You need to get an E6B mechanical flight computer, also called a Whiz Wheel. It makes this all a lot easier and you do not have to worry about batteries failing. Plus you can actually see how it works.
