Amazing how almost everyone who actually hasn't used a real AOA system dismisses the concept out of hand.

Not me. I'd love one. I merely stipulate that it needs to measure the actual AOA (whether by a vane or differential pitot pressures I don't care), and not *assume* the AOA because of some guesstimated data input to a PDA or "vario" or whatever.

I'm a computer programmer with experience doing embedded stuff. As a result, I have much less faith in them than many others do!

Also, it's FAR easier to optimise something -- that is, to find the maximum or minimum of a smooth function -- than it is to precisely predict the location of a discontinuity such as a stall.
