SECTION 4 – MFD
4.3 ENGINE INDICATION SYSTEM
WINDOW
The G1000 Engine Indication System (EIS) window
provides gauges, bar graphs and numeric readouts of en-
gine and airframe systems parameters to the pilot. The
EIS window is displayed on the left side of the MFD dur-
ing normal operations. In reversionary mode, the PFD
and MFD both show the EIS window.
The EIS contains three distinct pages, which are
accessed by the ENGINE softkey:
• Engine (default)
• Lean
• System
ENGINE Page
The Engine page is the default EIS page, which displays
engine, fuel and airframe/electrical indicators. Atop this
page are round dial gauges with a white pointer and digital
readouts for manifold pressure and revolutions per minute
(RPM). Below those gauges are color-coded horizontal bar
indicators with triangle pointers and numeric readouts in
-
dicating fuel quantity (no numeric readout), fuel flow (not
color-coded), oil pressure, oil temperature, exhaust gas
temperature (EGT) of the hottest cylinder – for normally
aspirated aircraft, turbine inlet temperature (TIT) – for tur-
bocharged aircraft, and cylinder head temperature (CHT)
of the hottest cylinder. The pointer on the horizontal bar
indicators appears in white, which represents acceptable
areas of operation. The pointer color changes to yellow or
red upon exceeding areas of normal operation.
The green band is indicative of normal areas of opera-
tion. Located at the bottom of the page are the electrical
indicators. A numeric readout is provided for the battery
voltage, essential bus voltage, and the alternator amperage.
Manifold Pressure Gauge
The Manifold Pressure gauge displays the engine power
in inches of mercury (in Hg). There are two color bands on
the Manifold Pressure gauge, green and red.
• Green – Normal operating range.
•
Red – (Top of arc) – Maximum manifold pressure.
Tachometer
The Tachometer displays propeller speed in revolu-
tions per minute (RPM). There are three color bands on
the Tachometer.
• White –
Below normal flight operating range.
• Green – Normal flight operating range.
• Red – Indicates propeller overspeed.
Fuel Qty Indicator
The Fuel Quantity indicator displays the quantity of
fuel in the tanks in gallons. The indicator ranges from E
(Empty) to F (Full) with tick marks at 10, 20, 30, and 40
gallons. Two triangle pointers labeled L (Left) and R (Right)
indicate the number of gallons in each fuel tank. There are
two color bands on the Fuel Quantity indicator.
• Yellow – Caution
• Red – Warning
NOTE: The Fuel Quantity Indicator will only dis-
play to 50 gallons when full, regardless of actual
maximum capacity.
NOTE: The pilot should refer to the Aircraft Flight
Manual Supplement (AFMS) for actual minimum/
maximum operating parameters associated with
EIS display indications.
