STALL WARNING

An electronic stall warning horn forward of the instrument
panel sounds a warning signal while there is time for the pilot
to correct the attitude. The signal is triggered by a sensing
vane on the leading edge of the left wing and is effective in all
flight attitudes and at all weights and airspeeds. Irregular and
intermittent at first, the warning signal will become steady as
the airplane approaches a complete stall.
The stall warning horn is inoperative when
the batteries and alternator switches are
turned off. Airplane certification requires the
stall warning system to be on during flight
except in emergency conditions as stated in
Section 3, EMERGENCY PROCEDURES.
A switch on the left subpanel placarded STALL WARN HEAT
controls electrical power to the stall warning heater elements.

ICE PROTECTION SYSTEMS

SURFACE DEICE SYSTEM

Deice boots cemented to the leading edges of the wings, hori-
zontal tail surfaces and vertical tail surface are operated by
engine-driven pump pressure. Compressed air, after passing
through the pressure regulators, goes to the distributor mani-
fold. When the deice system is not in operation, the distributor
valve applies vacuum to the boots to deflate and hold the
boots flat against the surface. Then, when the deice system is
operated, the distributor valve changes from vacuum to pres-
sure and the boots inflate. After the cycle is completed, the
valve returns to vacuum hold-down.
A three-position, spring loaded switch, with a center OFF posi-
tion, a down MAN (manual inflate) position, and an up SUR-
FACE AUTO position, controls the system. When the switch is
