STALL WARNING SYSTEM
The airplane is equipped with a pneumatic type stall warning
system
consisting of an
inlet in
the
leading
edge of the left wing,
an
|air-operated
horn near
the
upper left
corner
of the windshield,
and
associated plumbing. As the airplane approaches a stall, the low
pressure on the upper surface of the wings moves forward around
the leading edge of the wings. This low pressure
creates
a
differential
pressure in the stall warning system which draws air
through the warning horn, resulting in an audible warning
at
5
to
10
knots above stall in all flight conditions.
