Summary:

The stall-warning indicator employs a total-head tube located close to the wing surface in a region wherein local stalling occurs before the main portion of the wing stalls. The artificial production of a localized stalled region is accomplished by means of a sharp leading edge extending a few inches along the span. An abrupt drop in the total pressure relative to a static reference taken at some convenient point occurs at the stall n this region. This drop in total pressure causes the contraction of a pressure cell to which the total-head tube and the static orifice are connected and closes an electrical circuit that actuates a warning signal.
