I haven't had time to read all the above posts, but people are obviously getting rather worked up by the debate.
This debate has been going on for decades:
I remember an AAIB report touched on this matter. If I recall correctly, c. 1990 a C150 flown by a father with his son as a passenger, crashed when turning 180 degrees from a headwind to a tailwind. The flight was part of a low-level navigation competition in Hampshire and the aircraft was flying slowly so as be precisely on time. Tragically both were killed in the crash. The AAIB report, if I recall correctly, gave credence to the theory of the proposing side of this argument. Perhaps somebody will find the AAIB report? It generated a huge debate.
Whatever, as a practical (as opposed to a theoretical) pilot, when I do a similar turn, my eye is always steadfast on the ASI!
