Stall Warning System - Textron Cessna Grand Caravan Ex 208B Pilot's Operating Handbook And Faa Approved Airplane Flight Manual

SECTION 7
AIRPLANE AND SYSTEMS DESCRIPTION

STALL WARNING SYSTEM

The airplane is equipped with a vane-type stall warning unit, in the
leading edge of the left wing, which is electrically connected to a stall
warning horn located overhead of the pilot's position. The vane in the
wing senses the change in airflow over the wing, and operates the
warning horn at airspeeds between 5 and 10 knots above the stall in all
configurations.
The stall warning system should be checked during the preflight
inspection by momentarily turning on the BATTERY switch and
actuating the vane in the wing. The system is operational if the warning
horn sounds as the vane is pushed upward. The elevator must be off
the forward stop before the stall warning horn is enabled due to the fact
that the airplane is equipped with a stall warning ground disconnect
switch.
A pull-off type circuit breaker, labeled STALL WARN, protects the stall
warning system. Also, it is provided to shut off the warning horn in the
event it should stick in the on position.
This circuit breaker must be closed (pushed in) for
approach and landing.
The vane and sensor unit in the wing leading edge is equipped with a
heating element. The heated part of the system is operated by the
STALL HEAT switch on the ANTI-ICE switch panel, and is protected by
the STALL WARN circuit breaker on the left sidewall switch and circuit
breaker panel.
