Read the link at post #102 and you will find a rational explanation of the effect of the wind during turning flight.
No, you will not, you will find complete nonsense which ignores physics, couched in pseudo-scientific terms not understood by the author.
I'll ask you the same question that the other Myth-ers couldn't handle. (either refused to answer or answered incorrectly)
2 identical airplanes with a cruise airspeed of 100 knots. Both are flying east. Airplane A is in still air. Airplane B is flying into a 50 knot wind blowing out of the east. Both turn 180 degrees and fly west. What is the change in velocity from before the turn to after the turn for each plane?
