7.19 INSTRUMENT PANEL
The instrument panel (Figure 7-15) is designed to accommodate instruments and avionics equipment
for VFR and IFR flights.
The radios and the circuit breakers are located on the upper and lower right panel respectively, and have
circuits provided for the addition of optional radio equipment. 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 provide 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 installed 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.
