AFAIK, you can't do that with any precision unless you know Mach number, since stall AoA is Mach dependent, so my question is how did your F4 AoA gauge work in a UAS situation?
I dont know, how it was done, what input it used. Im no techicianŽand also technically very interested i never questioned the functioning of the AOA. It was there, it was always working, also with a iced up pitot tube (we only had one).
I donŽt see the problem there, the information was present in the AF447 aircraft (Stall warning, FDR traces....), it was not displayed.
