HN, AoA- or side- or pitch-string a correct name is not vitalli for a 20" wool-fathom
how exact will it work outside the side window of an A330??
between 2 and 3 deg is my expectation,
so mayby it is not exact enough to deside if AoA is 4 or 5 deg, but il will react very fast every time and for sure even with slow speed (<<60kn) and you can absolute shure distinguish between highspeed and stall,
it is so easy to check out, I hope that we find a jet-captain for a honest try
