I don't know if using AoA for safety would really work in a glider unless it was mounted and calibrated to remove gusts and other abnormalities. One idea would be a speed sensor matched with AoA over a 10 second gap below 1000'agl. Then all it does is say "speed speed" like bitching Betty.
I guess it's important to point out that the is a big difference in pitch and AoA in our type of Ops.
I think they could be useful matched to a Johnson type of drag meter.
I.e. Flap setting vs speed in different thermal strengths.
AoA to fly on long skinny glides and near the ground.
AoA to fly with underpowered turbos
AoA to fly in wave
I guess at some point we will move to HUD's. Once we do that there will be a plethora of stuff available to us. I guess the speed to fly will be a pipper based on track and macready, perhaps it will default to AoA at stable critical times such as the classic low level stall spin.
Just a thought from someone who flew the death pencil "Metroliner" and the AoA was pretty important.

Some years ago, I was asked to evaluate an AOA sensor (vane type,
mounted on a Duo, with an audio warning). Even in a relatively
smooth thermal, it squawked often for no good reason (I'm pretty
familiar with the Duo and my thermalling doesn't really suck bad).
With sensitivity turned down, it didn't give indication until
too late to be helpful (yes, I know, I already stalled).
I don't know whether it is possible to make something that
is helpful safety-wise. With a gear-down interlock it won't
help the guy thermalling low.
For what its worth from somebody who has tried one in a glider,
Best Regards, Dave
