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?

My Johnson Rocket has no stall warning devise, nor stall strips, yet it
gives a nice, straight-ahead stall, with plenty of warning, and was a
real hot rod by 1946 standards.
