I thought the wind vane like device on the early Moth machines was a paddle which was spring loaded and was pushed back by the action of air and therefore a crude ASI rather than AoA indicator?. Not studied this so could be wrong but certainly looked that way when I last saw one at the Moth fly in.
formationfoto,
You could be right. I was, I admit, basing my assumption on that from what a Tiger Moth pilot told me when we were discussing AoA indicators. He had always presumed this was actually an AoA indicator, so maybe he was wrong.
I think we've all taken rude pills - under another guise, and in a different forum, it has been interesting to see how a post can become the prompt for massive unexpected controversy. I guess the relative anonymity of forums along with the 'free speech' ethic leads to beheviour which we would find difficult to justify face to face.
Yes, indeed. I was just rather surprised such an apparently innocuous topic excites so much controversy.
I guess one of the points that some of the posters missed was the fact that the supercub, particularly the larger engine variants, can sit in the air with the ASI off the clock as you describe. Makes tail chasing with less capable machines quite fun, they just go sailing past.
I have relatively little faith in my ASI above 55 knots and practically none below that, which I suspect is how it should be. Gross position error at the low speeds at which the Super Cub stalls and its relatively low cruise speed make the ASI a severely limited instrument for this aircraft. It's not useless, obviously, but it has severe limitations just when you want to rely on it most -- during a low and slow powered approach.
