Pitot And Static System; Vacuum System; Stall Warning - Beechcraft Bonanza V35B Pilot Operating Handbook

PITOT AND STATIC SYSTEM

VACUUM SYSTEM

Vacuum for air driven gyroscopic flight instruments and other air driven equipment is supplied by an
engine driven vacuum pump. An adjustable relief valve controls suction by bleeding outside air into the
vacuum pump. The relief valve and an oil separator, which removes oil from the air, are located on the
forward side of the firewall.

STALL WARNING

To help prevent accidental stalls, a warning horn sounds as an incipient stall develops, while there is
time for the pilot to correct the attitude. The horn, triggered by a sensing vane forward of the flap on
the left wing, is effective in all flight attitudes and at all weights and airspeeds.
The pitot and static system provides a source of impact
and static air for the operation of the altimeter, rate of
climb and airspeed indicator. The pitot mast is located on
the leading edge of the left wing. The static system
provides a source of static air to the flight instruments
through a flush static fitting on each side of the airplane
fuselage.
Heating the Pitot element is essential. The heater switch is
located on the switch panel on the pilot's lower instrument
panel.
A suction gauge indicates system vacuum in inches Hg. This
instrument is located on the instrument panel; exact location may
vary according to panel configuration. The vacuum should be
maintained within 4-6 In.Hg. for proper operation of the air driven
instruments.
