Re: stall warner at high speed during aeros?
As an ex-flying instructor, may I point out that in the stalling exercises, one demo was to be flying along, minding ones own business and suddenly heave hard back on the control column. Due to inertia the aircraft took a little time to respond to this control input, so the angle of attack went through the roof. The student needed to note that this caused the stall warner to sound and that this was a "high speed stall".
P.P.
