Default AoA keep it going!

By approach stalls, so you mean stall on final approach? I thought that
was a rare accident gliders, and that most stalls during landing
occurred in the turns.

but there are more distractions - including that
noisy thing in the front just waiting to quit! Yet they mandate stall
warnings.


I don't know the reason that it's mandated, but that noisy thing up
front does change things significantly. For example, under power in my
motorglider, the nose attitude at 50 knots can vary from below the
horizon to above the horizon; the attitude while gliding at 50 knots is
constant and consistent. So, I suggest determining a safe AOA is harder
in powered aircraft, and this makes a stall warning more valuable.
