Are you contradicting your previous comment: "Some studies I've seen
have shown that pilots are often oblivious to warning horns and
lights, though stick shakers are effective."?

No, the discussion has vacillated between AOA indicators and warnings;
there is more justification for improved warnings than for indicators
which won't be used.

BTW, I do agree that AOA indicator would be *useful* in the right
hands (precise short field landings, e.g.), but I don't think it will
make much of a dent int he stall/spin accidents.

I'd like to think it's a solvable problem, or at least reducable.

Planes that fly themselves? ;-)
