Stall ALWAYS occurs at the same AoA, never at the same airspeed. PLUS,
the ASI will tell you you are about to stall when it's too late, you
already have. AoA gives instant response and tells you AoA has changed
so ASI is now going to change but not for 20 seconds or so. The airplane
has inertia so does not change speed instantly.
All relevant speeds vary with weight, temperature, pressure etc but AoA
does not, it is consistent.
Imho, ASI is a secondary flight instrument, useful for navigation, AoA
is the primary one, or should be.

btw there are two stall conditions, flaps down and clean, not the same
but you knew that anyway ,,,,,,,,,,,

in the Europa, the AoA varies greatly between flyable speeds between 50 and
150 knots. It's the stall that i am interested in, and that has little to do
with
the Angle of Attack. But please correct me if this makes no sense!
