Yes, *if* the AOA is effectively communicated to the pilot.

You're really just talking about a more effective stall warning
system. Fine.

But a simple AOA detector that will directly reduce

Hypothesis. Skydivers point out that in spite of all the new safety
equipment they have these days, the fatality rate stays about the
same. People will always push the limits to achieve what they
consider an "acceptable" risk.

Consider that the unstallable airplanes such as the Ercoupe didn't
show any improvement in accident rates.

Just throwing up our arms while people continue to
die is not good enough.

The sure-fire way to reduce the fatality rate is to add ballistic
parachutes to our aircraft....no, wait, that hasn't worked either.
;-)

I don't know the solution to the problem. It may be an unavoidable
aspect of our freedom to fly.
