Al you are missing a couple points, one on a full scale airplane you really would not care about the ground track, the and a 15 knot wind is not going to have as much effect on a full scale airplane as it has on a model. You seem to believe that without any any type of correction that the airplane would drift with the wind direction. So let me ask this question of you. How would one control the drift while keeping wings level? And let me state once again, I have won numerous pattern and IMAC contests using this technique, I'm not just blowing smoke here.
I do agree that airplanes do not see wind, they only see airspeed but they also drift with the wind direction if in a cross wind. If your statements were true then landing in a cross wind would be the same as landing in a head wind correct?
