As an aside, is there a condition of flight that will allow the plane to stall without the stall warner going off? For example, a skidding turn so that the airflow over the stall warner is disrupted?
I imagine that it would not make much different as the stall is related to the lowering of the stagnation point and that is what pushes the switch up. If the stagnation point is 'high' then by definition, the wing has a low AoA. That's the way I see it. Most likely somebody will point out something not considered.
it would be quite possible that the inside wing could stall before the warner (on the outside wing) reaches it's trigger AoA.
As far as I am aware, most light a/c are designed to stall at the root first. A tip stall can be induced with a power on stall.
