The builder of my 320 designed and built-in a stall = warning device.

It consists of a raised section of upper surface skin on = the left wing (about 5 mm), and around 30 mm wide, aerodynamically = shaped.

The increasing AOA producing some increase in pressure on = the upper surface causes contacts to make and an aural stall warning comes = in about 15 knots above the demonstrated clean power off = stall.

It’s simple and it works.

Cheers
