master switch should be turned off for l second to reset the overvoltage
relay. If the ammeter continues to indicate no output, electrical load should
be maintained at the absolute minimum and the flight should be terminated
as soon as practicable.
7.17 INSTRUMENT PANEL
The instrument panel (Figure 7-13) is designed to accommodate
instruments and avionics equipment for VFR and IFR flight.
Radio equipment is mounted in the center and right instrument panel;
flight instruments are mounted on the left. An engine instrument cluster in
the lower instrument panel just right of the control quadrant includes a fuel
pressure gauge, an ammeter, an oil temperature gauge and an oil pressure
gauge. Fuel quantity indicators for each tank are mounted in the control
quadrant on either side of the fuel selector. The tachometer is located to the
left of the control quadrant. The alternator warning light is in the upper left
instrument panel.
Circuit breakers are on the lower right of the instrument panel and
electrical switches are just left of the control quadrant. Heater controls are
to the left of the pilot’s control wheel. Fresh air vents are located to the
extreme left and right lower corners of the instrument panel.
Standard instruments include a compass, an airspeed indicator, a
recording tachometer, an altimeter, the engine instrument cluster, the fuel
quantity gauges and the alternator warning light. The magnetic compass is
mounted in the center of the cockpit at the top of the windshield.
A variety of optional items are available for installation in the
instrument panel. These options include a suction gauge on the upper left;
an attitude gyro, a directional gyro, a true airspeed indicator, a vertical
speed indicator and a turn coordinator in the flight instrument group; and
an aircraft hour meter on the extreme right of the panel. The gyros are
vacuum operated through the optional vacuum system, and the turn
coordinator is electric. An optional primer system* is operated by a primer
pump to the lower right of the control quadrant. An electric clock is
available for installation in the upper left corner of the panel. The optional
outside air temperature gauge is located in the overhead cockpit area.
*Standard on aircraft with serial nos. 38-79A0001 and up. Optional on
earlier aircraft.
