DESCRIPTION & OPERATION
7.19 INSTRUMENT PANEL
The instrument panel (Figure 7-15) is designed to accommodate instru-
ments and avionics equipment for VFR and IFR flights.
The radios and the circuit breakers are located o.n the upper and lower
right panel, respectively, and have circuits provided for the addition of
optional radio eql;lipment. An optional radio master switch is located near
the top of the instrument panel between the radio stacks.
It
controls the power
to all radios through the aircraft master switch. An emergency bus switch is
also provided to supply auxiliary power to the avionics bus in event of a radio
master switch circuit failure. The emergency bus switch is located behind the
lower right shin guard, left of the circuit breaker panel. An engine cluster is
located to the right of the pilot control wheel and includes a fuel pressure
gauge, a right and left main fuel quantity gauge, an oil temperature gauge
and an oil pressure gauge.
Standard instruments include a compass, an airspeed indicator, a
tachometer, an altimeter, an ammeter, an engine cluster, and an annunciator
panel. The compass is mounted on the windshield bow in clear view of the
pilot. The annunciator panel is mounted in the upper instrument panel to
warn the pilot of a possible malfunction in the alternator, oil pressure, or
vacuum systems.
Instrument options available for the panel includes a suction gauge,
vertical speed indicator, attitude gyro, directional gyro, clock, tru-speed
indicator and a turn and slip indicator or turn coordinator. The attitude gyro
and directional gyro are vacuum operated through the use of a vacuum
pump inst;liled on the engine, while the turn and slip indicator is electrically
operated. The vacuum suction gauge is on the far right of the instrument
panel.
