for me. I don't see what an AoA instrument could add to this. If you are
distracted enough to get slow with an ASI, then I see no reason why you
wouldn't be distracted enough to get slow with an AoAI.

This seems to be the real reason people stall. It's not that they
don't know what the speed is, it's that they can't maintain the speed
that they do know !

An indicator for an AoA meter could consist of something as simple as
three LEDs, say a bright red one for approaching stall, green for
minimum sink, blue for best L/D and above, with the red LED blinking
faster as AoA gets closer to stall.

You could do all that with a single, tri-colour LED, though the colors
would be red/yellow/green. The single LED may well be easier to mount
and I doubt you'd miss any information by having all the colors at the
same point - nobody has (yet) suggested any form of bar-graph display.
