conventional manner; in the full forward position, the throttle is open, and
in the full aft position, it is closed. A friction lock, which is a round knurled
idisk, is located at the base of the throttle and is operated by rotating the
lock clockwise to increase friction or counterclockwise to decrease it.
The mixture control, mounted near the propeller control, is a red knob
with raised points 'around the circumference and is equipped with a lock
button in the end of the knob. The rich position is full forward, and full aft is
the idle cut-off position. For small adjustments, the control may be moved
forward by rotating the knob clockwise, and aft by rotating the knob
counterclockwise. For rapid or large adjustments, the knob may be moved
forward or
aft
by depressing the lock button in the end of the control, and
then positioning the control as desired.
ENGINE INSTRUMENTS
Engine operation is monitored by the following instruments: oil
pressure gage, oil temperature gage, cylinder head temperature gage,
tachometer, and manifold pressure gage. An economy mixture (EGT)
indicator and carburetor air temperature gage are also available.
The oil pressure gage, located on the right side of the instrument panel,
is operated by oil pressure. A direct pressure oil line from the engine
delivers oil at engine operating pressure to the oil pressure gage. Gage
markings indicate that minimum idling pressure is 10 PSI (red line), the
normal operating range is 30 to 60 PSI (green arc), and maximum pressure
is 100 PSI (red line).
Oil temperature is indicated by a gage adjacent to the oil pressure
gage. The gage is operated by an electrical-resistance type temperature
sensor which receives power from the airplane electrical system. Gage
markings indicate the normal operating range (green arc) which is 100°F
(38°C) to 240°F (116°C), and the maximum (red line) which is 240°F (116°C).
The cylinder head temperature gage, under the left fuel quantity
indicator. is operated by an electrical-resistance type temperature sensor
on the engine which receives power from the airplane electrical system.
Gage markings indicate the normal operating range (green arc) which is
200°F (93
C
C) to 460°F (238°C) and the maximum (red line) which is 460°F
(238°C).
The engine-driven mechanical tachometer is located on the lower right
side of the instrument panel. The instrument is calibrated in increments of
100 RPM and indicates both engine and propeller speed. An hour meter
below the center of the tachometer dial records elapsed engine time in
hours and tenths. Instrument markings include a normal operating range
