The stall warning can scream all day, its a matter of angle of attack it wont stall with the nose pointing down.
I have done a full 1 hr flight with the stall warning going off, practicing slow flight, slow approaches, slow turns and so on.
For the plane to stall I need to pull the yoke almost all the way back, and the angle of attack is high by then.
When the AoA shows 1 yellow the stall warning goes off.
After the yellow there is 1 blue (no lift no sink) then 6 reds.
The plane stalls at 3 red lights with power on.
In this kind of approach I only look at the AoA indicator on long final, then dont look at nothing inside and all outside, and fly it by feel and sounds also the nose of the plane picture helps calculating the AoA .
Where the AoA indicator helps a lot is setting up for the approach, like a slow base turn to final kind of thing.
Im not an instructor or expert , this is just what it works for me in my plane , so always open to hear other's opinions.
