The Falco had an aerodynamic rather than mechanical. There's a false
leading edge on about 6 inches of the wing which causes turbulent air over
that section and makes a buffeting on the wing to give the indication of an
impending stall.

I personally haven't flown an airplane with a stall warning in about 250
hours (last 5 years or so) and, quite frankly, would rather do without the
racket.

Researching a question from a club member, I read in the FAR's:

§ 23.207 Stall warning.
[...]
(b) The stall warning may be furnished either through the inherent
aerodynamic qualities of the airplane or by a device that will give
clearly distinguishable indications under expected conditions of flight.

Every plane I've ever flown has a mechanical stall warning device (some
visual, some aural), but apparantly it's possible to certify a plane
without one. Does anybody know of any real life examples of planes
certified without stall warning devices?
