ENGINE CONTROLS
(Continued)
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 cutoff 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
The GI000 Engine Indicating System (EIS) provides graphical
indicators and numeric values for engine, fuel, and electrical system
parameters to the pilot. The EIS is shown in a vertical strip on the
left side of the PFD during engine starts and on the MFD during
normal operation. If either the MFD or PFD fails during flight, the
EIS is shown on the remaining display.
The EIS consists of three pages that are selected using the ENGINE
softkey. The ENGINE page provides indicators for Manifold
Pressure, Tachometer, Fuel Flow, Oil Pressure, Oil Temperature,
Cylinder Head Temperature (CHT), Exhaust Gas Temperature
(EGT), Fuel Quantity, Electrical Bus Voltages, and Battery Currents.
When the ENGINE
softkey is pressed, the LEAN and SYSTEM
softkeys appear adjacent to the ENGINE softkey. The LEAN page
provides simultaneous indicators for CHT and EGT on all cylinders
to be used for adjusting ("leaning") the
fuellair mixture. The
SYSTEM page provides numerical values for parameters on the
ENGINE page that are shown as indicators only.
The SYSTEM
page also provides an indicator for vacuum (VAC) and a digital
value for fuel used (GAL USED).
The GEA-71 Engine and Airframe Unit, located forward of the
instrument panel, receives signals from the
enginelsystem sensors
for the parameters that are being monitored. The GEA-71 provides
data to the
EIS, which displays the data for the ENGINE page
described below.
