Sta
ll warning system
The airplane is equipped with an electrically deiced stall sensor in the leading edge of
the right wing. This sensor fitted with a vane is electrically connected to an audible
warning. The vane senses the change in airflow over the wing and operates the
warning unit, which produces an aural warning alert over the alarm speaker. This
warning alert begins 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 SOURCE selector and by manipulating the vane in the
wing.
>> Without voice alerts (Pre-MOD70-0407-00D)
The system is operational if a continuous tone (low-pitched sound) is heard on the
alarms speaker.
>> With voice alerts (Post-MOD70-0407-00D)
The system is operational if a stall aural warning alert is heard on the alarms speaker.
● NOTE ●
The audible stall warning may be altered by severe or prolonged icing.

Static dischargers
As an aid in flight, static dischargers are installed to improve radio communications
dur
ing flight by reducing interference from dust orvarious formsof precipitations (rain,
snow or ice crystals).
Under these conditions, the build-up and discharge ofstatic electricityfrom the trailing
edges of the wings (flaps and ailerons), rudder, stabilator, propeller tips and radio
antennas can result in loss of usable radio signals on all communications and
navigation radio equipment. Usually, the ADF is first and VHF communication
equipment is the last to be affected.
Installation of static dischargers reduces interference from precipitation static, but it is
possible to encounter severe precipitation static conditions which might cause the
loss ofradio signals,even with static dischargers installed. Wheneverpossible, avoid
known severe precipitation areas to prevent loss of dependable radio signals. If
avoidance is impractical, minimize airspeed and anticipate temporary loss of radio
signals while in these areas.
