ENGINE INDICATION SYSTEM

7.1 INTRODUCTION

The G1000 Engine Indication System (EIS) is designed
to provide gauges, bar graphs and numeric readouts of
engine parameters to the pilot. The EIS is displayed on
the left side of the MFD during normal operations.

NOTE: Refer to the System Overview for informa­tion regarding reversionary mode.

EIS PAGES

The EIS contains three distinct pages, which are
accessed by the ENGINE softkey:

• Engine Page – This is the default page, which
displays all critical engine, fuel and electrical
indicators.

• Lean Page – This page provides engine leaning
information and a user interface to perform engine
leaning.

• System Page – This page displays a numeric
readout for the critical engine, fuel and electrical
indicators.

EIS INDICATORS

The EIS Pages consist of round dial gauges, horizontal
bar indicators, bar graphs (Lean Page only) and digital
readouts:

Round Dial Gauges

The gauges are color-coded and have a white pointer.
A digital readout appears beneath both gauges and does
not change color.

Horizontal Bar Indicators

These indicators are color-coded and have triangular
pointers. The pointers appear in white, representing areas
of normal operation. The pointer color changes to yellow
or red upon exceeding areas of normal operation. The
green band is indicative of normal operations.

Bar Graphs (Lean Page Only)

Each bar graph is numbered and represents a cylinder.
The graphs appear white (when a cylinder is selected
that graph changes to cyan), representing areas of normal
operation. The color changes to yellow or red upon
exceeding areas of normal operation.

Digital Readouts

These readouts appear as white text on a black
background, representing areas of normal operation.
The color changes to black text on a yellow background
(caution) or white text on a red background (warning)
upon exceeding areas of normal operation.

7.2 ENGINE PAGE

Atop all three pages are two round dial gauges for
manifold pressure and revolutions per minute (RPM).
Beneath those gauges are horizontal bar indicators for fuel
flow, cylinder head temperature (CHT), oil temperature,
oil pressure, alternator amperage, bus voltage and fuel
quantity.

Manifold Pressure Gauge

The Manifold Pressure gauge displays the engine power
in inches of mercury (in Hg).

• Green – Normal operating range.

• White (top of arc) – Above normal operating
range.

Tachometer

The Tachometer displays propeller speed in revolutions

per minute (RPM).

• White – Below normal flight operating range.

• Green – Normal flight operating range.

• Red – Propeller overspeed.

Fuel Flow GPH Indicator

Fuel Flow Leaning Pointer

The Fuel Flow Leaning Pointer provides a leaning
reference for the pilot during a Max Power Climb (MPC)
or Cruise Climb. The pointer is displayed on the bottom
of the Fuel Flow indicator if the RPM exceeds 2530, or fuel
flow exceeds a specified value based on altitude during a
MPC or Cruise Climb (see table below).

The Oil Pressure indicator displays the pressure of the
oil supplied to the engine in pounds per square inch (PSI).

• Green – Normal

• Yellow – Caution

• Red – Warning (minimum and maximum)

Voltmeter

The Voltmeter displays the primary bus voltage. The
Voltmeter displays two (2) pointers which indicate the
voltage for Buses 1 and 2.

• Green – Normal

• Yellow – Caution

Fuel Qty GAL Indicator

The Fuel Quantity indicator displays the quantity of
fuel in the tanks, in gallons. Two (2) triangular pointers
labeled L (left) and R (right) indicate the number of gallons
in each fuel tank. The indicator ranges from 0 to 37 with
major tick marks at 0 and 37 and minor tick marks at 3
gallon intervals.

• Green – Normal

• Yellow – Caution

• Red – Warning (0 red tick mark)

Ammeter

7.3 LEAN PAGE

The Lean Page is accessible by pressing the LEAN
softkey. A digital readout for fuel flow resides below
the tachometer. Beneath the fuel flow indication are bar
graphs and numeric readouts for exhaust gas temperature
(EGT) and cylinder head temperature (CHT) in degrees
Fahrenheit. The temperature deviation from peak resides
above the EGT graph. By default, the numeric readouts of
the EGT and CHT are associated with the hottest cylinder
and are graphically indicated in cyan (light blue). Color
coding for the EGT and CHT bar graphs is listed below:

• Cyan (light blue) – Selected Cylinder (EGT and
CHT)

• White – Normal (EGT and CHT)

• Yellow – Caution (CHT only)

• Red – Warning (CHT only)

leaning process. When a cylinder peaks, its peak is
represented by a single cyan line on the EGT bar graph.
The EGT readout for the peaked cylinder, indicated in cyan
(light blue), appears directly beneath the bar graph. The
system automatically switches to the first peak obtained
and displays the temperature deviation from peak in
degrees Celsius above the EGT bar graph.

7.4 SYSTEM PAGE

The System Page is accessible by pressing the SYSTEM
softkey. The readouts on this page are separated into three
categories: System, Fuel Calculation and Electrical.

System

• OIL ºC – Oil temperature in degrees Celsius

• OIL PSI – Oil pressure in pounds per square inch

Fuel Calculation

The fuel calculation portion of the System Page is based
on the fuel flow totalizer and displays the following:

• FFLOW GPH – Fuel flow in gallons per hour.

• GAL REM – Current fuel remaining in gallons as
set by the pilot and adjusted for fuel burn since
last set.

• GAL USED – Quantity of fuel used in gallons.

• ENDUR – Flight time remaining with fuel
onboard (HH:MM when more than an hour
remains).

• RANGE NM – Aircraft range in nautical miles.

To decrease the fuel totalizer quantity:

1. From the System Page, press the
softkey to obtain the desired number of gallons
remaining.

To increase the fuel totalizer quantity:

1. From the System Page, press the
softkey to obtain the desired number of gallons
remaining.

To reset the fuel totalizer:

1. From the System Page, press the
softkey. This also resets the GAL USED to
zero.

Electrical

• ALT LOAD – Alternator load in amperes

• BUS VOLTS – Primary bus voltage

NOTE: Refer to the Pilot’s Operating Handbook
(POH) for limitations.

DEC FUEL

INC FUEL

RST FUEL

Fuel calculations do not use the aircraft fuel quantity
indicators and are calculated from the last time the fuel
was reset.

If desired, the pilot can utilize the DEC FUEL, INC
FUEL and RST FUEL softkeys to adjust the amount of
fuel remaining for totalizer calculations.

• DEC FUEL – Decreases totalizer based fuel
quantity remaining in one gallon increments.

• INC FUEL – Increases totalizer based fuel
quantity remaining in one gallon increments.

• RST FUEL – Reset totalizer based fuel quantity
remaining relative to the aircraft fuel capacity.
Performing the fuel reset also sets the GAL USED
display to zero.
