WARNINGS & CAUTIONS

WARNING:

Navigation and terrain separation must NOT be predicated upon the use of the terrain
function. The G1000 Terrain Proximity feature is NOT intended to be used as a primary reference for
terrain avoidance and does not relieve the pilot from the responsibility of being aware of surroundings
during flight. The Terrain Proximity feature is only to be used as an aid for terrain avoidance and is not
certified for use in applications requiring a certified terrain awareness system. Terrain data is obtained
from third party sources. Garmin is not able to independently verify the accuracy of the terrain data.

WARNING:

The displayed minimum safe altitudes (MSAs) are only advisory in nature and should not be
relied upon as the sole source of obstacle and terrain avoidance information. Always refer to current
aeronautical charts for appropriate minimum clearance altitudes.

WARNING:

The Garmin G1000, as installed in Cessna Nav III aircraft, has a very high degree of functional
integrity. However, the pilot must recognize that providing monitoring and/or self-test capability for
all conceivable system failures is not practical. Although unlikely, it may be possible for erroneous
operation to occur without a fault indication shown by the G1000. It is thus the responsibility of
the pilot to detect such an occurrence by means of cross-checking with all redundant or correlated
information available in the cockpit.

WARNING:

For safety reasons, G1000 operational procedures must be learned on the ground.

WARNING:

The altitude calculated by G1000 GPS receivers is geometric height above Mean Sea Level
and could vary significantly from the altitude displayed by pressure altimeters, such as the GDC 74A
Air Data Computer, or other altimeters in aircraft. GPS altitude should never be used for vertical
navigation. Always use pressure altitude displayed by the G1000 PFD or other pressure altimeters in
aircraft.

WARNING:

The Jeppesen database used in the G1000 system must be updated regularly in order to
ensure that its information remains current. Updates are released every 28 days. A database information
packet is included in the G1000 package. Pilots using an outdated database do so entirely at their own
risk.

190-00498-00 Rev. Aii

WARNINGS & CAUTIONS

WARNING:

The basemap (land and water data) must not be used for navigation, but rather only for non­navigational situational awareness. Any basemap indication should be compared with other navigation
sources.

CAUTION:

The illustrations in this guide are only examples. Never use the G1000 to attempt to penetrate
a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Airman’s Information
Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or
giving an intense radar echo.”

CAUTION:

The United States government operates the Global Positioning System and is solely responsible
for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy
and performance of all GPS equipment. Portions of the Garmin G1000 utilize GPS as a precision
electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the
G1000 can be misused or misinterpreted and, therefore, become unsafe.

CAUTION:

To reduce the risk of unsafe operation, carefully review and understand all aspects of the
G1000 Pilot’s Guide documentation. Thoroughly practice basic operation prior to actual use. During
flight operations, carefully compare indications from the G1000 to all available navigation sources,
including the information from other NAVAIDs, visual sightings, charts, etc. For safety purposes, always
resolve any discrepancies before continuing navigation.

CAUTION:

CAUTION:

190-00498-00 Rev. A

The Garmin G1000 does not contain any user-serviceable parts. Repairs should only be made
by an authorized Garmin service center. Unauthorized repairs or modifications could void both the
warranty and the pilot’s authority to operate this device under FAA/FCC regulations.

The GDU 1040 PFD and MFD displays use a lens coated with a special anti-reflective coating
that is very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA
WILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean the lens using a clean, lint­free cloth and an eyeglass lens cleaner that is specified as safe for anti-reflective coatings.

WARNINGS & CAUTIONS

NOTE:

All visual depictions contained within this document, including screen images of the G1000 panel
and displays, are subject to change and may not reflect the most current G1000 system. Depictions of
equipment may differ slightly from the actual equipment.

NOTE:

This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

NOTE:

There are several atmospheric phenomena in addition to nearby thunderstorms that can cause
isolated discharge points in the strike display mode. However, clusters of two or more discharge points
in the strike display mode do indicate thunderstorm activity if these points reappear after the screen
has been cleared. Avoid the clusters to avoid the thunderstorms. In the cell display mode, even a single
discharge point may represent thunderstorm activity and should therefore be avoided.

System Overview

SYSTEM OVERVIEW

1.1 SYSTEM DESCRIPTION

This document is designed to provide an overview
of the G1000 Integrated Cockpit System as installed in
Cessna Nav III aircraft.

The G1000 system includes the following
Replaceable Units (LRUs):

• GDU 1040 Primary Flight Display (PFD)

• GDU 1040 Multi Function Display (MFD)

• GIA 63 Integrated Avionics Units (2)

• GEA 71 Engine/Airframe Unit

• GDC 74A Air Data Computer (ADC)

• GRS 77 Attitude and Heading Reference System
(AHRS)

• GMU 44 Magnetometer

• GMA 1347 Audio System with integrated Marker
Beacon Receiver

• GTX 33 Mode-S Transponder

• GDL 69/69A Data Link

The LRUs are further described in the following
section. All LRUs have a modular design, which greatly
eases troubleshooting and maintenance of the G1000
system. A top-level G1000 block diagram is given in
Figure 1-1. Additional or optional interfaces are depicted
in Figure 1-2.

NOTE:

Please refer to the Pilot’s Guide
Appendices for detailed specifications
regarding the G1000 LRUs.

Line

1.2 LINE REPLACEABLE UNITS

• GDU 1040 – The GDU 1040 features a 10.4-inch
LCD display with 1024 x 768 resolution. The left
display is configured as a PFD and the right display
is configured as an MFD. Both GDU 1040s link
and display all functions of the G1000 system
during flight. The displays communicate with
each other through a High-Speed Data Bus (HSDB)
Ethernet connection. Each display is also paired via
an Ethernet connection with a GIA 63 Integrated
Avionics Unit.

• GMA 1347 – The GMA 1347 Audio Panel integrates
NAV/COM digital audio, intercom system and
marker beacon controls. The GMA 1347 also
controls manual display reversionary mode (red
DISPLAY BACKUP button) and is installed
between the MFD and the PFD. The GMA 1347
communicates with both GIA 63s using an RS-232
digital interface.

SYSTEM OVERVIEW

• GIA 63 – The GIA 63 is the central Integrated
Avionics Unit (IAU) of the G1000 system. The
GIA 63 functions as a main communication hub,
linking all LRUs with the PFD and the MFD
displays. Each GIA 63 contains a GPS receiver, VHF
COM/NAV/GS receivers, and system integration
microprocessors. Each GIA 63 is paired with a
respective GDU 1040 display through Ethernet.
The GIAs are not paired together and do not
communicate with each other directly.

• GRS 77 – The GRS 77 is an Attitude and Heading
Reference System (AHRS) that provides aircraft
attitude and heading information to both the
G1000 displays and the GIA 63s. The unit
contains advanced sensors, accelerometers and rate
sensors. In addition, the GRS 77 interfaces with
both the GDC 74A Air Data Computer and the
GMU 44 Magnetometer. The GRS 77 also utilizes
GPS signals sent from the GIA 63. Attitude and
heading information is sent using an ARINC 429
digital interface to both GDU 1040s and GIA 63s.
AHRS modes of operation are discussed later in this
document.

• GMU 44 – The GMU 44 Magnetometer measures
local magnetic field information. Data is sent to the
GRS 77 AHRS for processing to determine aircraft
magnetic heading. This unit receives power directly
from the GRS 77 and communicates with the
GRS 77 using an RS-485 digital interface.

• GDC 74A – The GDC 74A Air Data Computer
processes information from the pitot/static system
as well as the outside air temperature (OAT) sensor.
The GDC 74A provides pressure altitude, airspeed,
vertical speed and OAT information to the G1000
system, and communicates with the GIA 63s,
GDU 1040s and GRS 77 using an ARINC 429 digital
interface.

• GEA 71 – The GEA 71 receives and processes signals
from the engine and airframe sensors. Sensor types
include engine temperature and pressure sensors as
well as fuel measurement and pressure sensors. The
GEA 71 communicates with both GIA 63s using an
RS-485 digital interface.

SYSTEM OVERVIEW

1.5 SYSTEM POWER-UP

The G1000 system is integrated with the aircraft
electrical system and receives power directly from electrical
busses. The Garmin G1000 PFD/MFD and supporting
sub-systems include both power-on and continuous built­in test features that exercise the processor, RAM, ROM,
external inputs and outputs to provide safe operation.

While the system begins to initialize, test annunciations
are displayed to the pilot at power-up, as shown in the
following figure. All system annunciations should be
cleared within one (1) minute of power-up. The
Panel also annunciates all bezel lights briefly upon power­up.

NOTE:

Please see the Aircraft Flight Manual
(AFM) for specific procedures concerning
avionics power application and emergency
power supply operation.

Audio

On the PFD, the AHRS system displays the ‘AHRS
ALIGN: Keep Wings Level’ message and begins to initialize.
The AHRS should display valid attitude and heading fields
within one (1) minute of power-up. The AHRS can align
itself both while taxiing and during level flight.

NOTE:

Please refer to the Pilot’s Guide
Appendices for AHRS initialization bank angle
limitations.

NOTE:

See the Annunciations and Alerts Pilot’s
Guide for additional information regarding
system annunciations and alerts.

SYSTEM OVERVIEW

1.6 DISPLAY BACKLIGHTING

The G1000 PFD and MFD displays use photocell
technology to automatically adjust for ambient lighting
conditions. Photocell calibration curves are pre-configured
to optimize display appearance through a broad range
of cockpit lighting conditions. The PFD, MFD, and
Audio Panel bezel/key lighting is normally controlled
directly by the existing instrument panel dimmer bus.

If desired, the PFD and MFD display backlighting may
be adjusted manually. The PFD, MFD and Audio Panel
bezel/key brightness can also be adjusted manually. The
Audio Panel bezel/key brightness is directly tied to the
MFD bezel/key adjustment.

NOTE:

Please refer to the Primary Flight Display
Pilot’s Guide for instructions on adjusting
backlighting manually.

1.7 SYSTEM OPERATION

NORMAL MODE

The PFD and MFD are connected together on a single
Ethernet bus, allowing for high-speed communication
between the two units. Each GIA 63 is connected to a
single display, as shown in Figure 1-1. This allows the
units to share information, thus enabling true system
integration.

In normal operating mode, the PFD displays graphical
flight instrumentation in lieu of the traditional gyro
instruments. Attitude, heading, airspeed, altitude
and vertical speed are all shown on one display. The
MFD shows a full-color moving map with navigation
information. Both displays offer control for COM and NAV
frequency selection, as well as for the heading, course/baro
and altitude reference functions. On the left of the MFD
display, the Engine Indication System (EIS) cluster shows
engine and airframe instrumentation. Figure 1-6 gives an
example of the G1000 system in normal mode.

1-12

Figure 1-6 Normal Mode

Garmin G1000 Pilot’s Guide for Cessna Nav III

190-00498-00 Rev. A

REVERSIONARY MODE

Should a failure occur in either display, the G1000
automatically enters reversionary mode. In reversionary
mode, all important flight information is shown on the
remaining display. An example of reversionary mode
entry due to a failed PFD is shown in Figure 1-7.

SYSTEM OVERVIEW

NOTE:

The system alerts the pilot when backup
paths are utilized by the LRUs. Refer to the
Annunciations and Alerts Pilot’s Guide for
further information regarding these and other
system alerts.

If a display fails, the GIA 63-GDU 1040 Ethernet
interface is cut off. Thus, the GIA can no longer
communicate with the remaining display (refer to Figure
1-1), and the NAV and COM functions provided to the
failed display by the GIA are flagged as invalid on the
remaining display, as a result. The system reverts to
using backup paths for the GRS 77, GDC 74A, GEA 71
and GTX 33, as required. The change to backup paths is
completely automated for all LRUs, and no pilot action is
required.

Reversionary mode may also be manually activated by
the pilot if the system fails to detect a display problem.
Reversionary mode is activated manually by pressing the
red DISPLAY BACKUP button at the bottom of the Audio
Panel. Pressing this button again deactivates reversionary
mode.

SYSTEM OVERVIEW

AHRS OPERATION

In addition to using internal sensors, the GRS 77
AHRS uses GPS information, magnetic field data and
air data to assist in attitude/heading calculations. In
normal (primary) mode, the AHRS relies upon GPS and
magnetic field measurements. If either of these external
measurements is unavailable or invalid, the AHRS uses air
data information for attitude determination. Four AHRS
modes of operation are available (see table below) and
depend upon the combination of available sensor inputs.
Loss of air data, GPS, or magnetometer sensor inputs is
communicated to the pilot by message advisory alerts.

GPS Input Failure

The G1000 system provides two sources of GPS
information. If a single GPS receiver fails, or if the
information provided from one of the GPS receivers is
unreliable, the AHRS seamlessly transitions to using the
other GPS receiver. An alert message informs the pilot of
the use of the backup GPS path. If both GPS inputs fail,
the AHRS continues to operate in reversionary ‘No GPS’
mode so long as the air data and magnetometer inputs are
available and valid.

Air Data Input Failure

A failure of the air data input has no effect on AHRS
output while AHRS is operating in normal/primary mode.
A failure of the air data input while the AHRS is operating
in reversionary ‘No GPS’ mode results in invalid attitude
and heading information on the PFD (as indicated by red
‘X’ flags).

Magnetometer Failure

If the magnetometer input fails, the AHRS transitions
to one of the reversionary ‘No Magnetometer’ modes and
continues to output valid attitude information. However,
the heading output on the PFD does become invalid (as
indicated by a red ‘X’).

NOTE:

Please refer to the Annunciations and
Alerts Pilot’s Guide for specific AHRS alert
information.

NOTE:

Pilots should be aware that aggressive
maneuvering in any of the three reversionary
modes listed below can degrade AHRS
accuracy.

2.1 INTRODUCTION

WARNING: In the event that the airspeed, attitude,
altitude, or heading indications become unusable,
please refer to the backup instruments.

This section describes the major features of the G1000
Primary Flight Display (PFD) as installed on Cessna Nav
III aircraft. Information is displayed using the G1000’s
two 10.4-inch color flat-panel displays. During normal
operation, the left display is configured as a Primary Flight
Display.

The PFD provides increased situational awareness by
replacing the traditional instrument “six pack” on the
pilot’s panel with an easy-to-scan display that provides
a large horizon and airspeed, attitude, altitude, vertical
speed, navigation, communication, annunciation,
terrain, traffic, and lightning (optional) information. The
PFD also controls the operation of the transponder, the
selection of NAV/COM frequencies, audio volume, and
many navigation features. The operation of these features
is explained in other supporting sections.

The G1000 system controls were designed so that,
regardless of which seat the pilot is flying from, the aircraft
can be flown with one hand and the controls manipulated
with the other hand.

The PFD displays the following:

• Navigation (NAV) Frequency Window

• Navigation Status Bar

• Communication Frequency Window

• Airspeed Indicator

• True Airspeed Box

• Attitude Indicator

• Slip/Skid Indicator

• Horizontal Situation Indicator

• Turn Rate Indicator

Course Deviation Indicator

The Course Deviation Indicator (CDI) moves to the left
or right of the course pointer along a deviation scale to
display aircraft position relative to the course.

The CDI has the same angular limits as a mechanical
CDI when coupled to a VOR or LOC. When coupled
to GPS, the full-scale limits for the CDI are defined by a
GPS-derived distance (5.0, 1.0, or 0.3 nm). The CDI scale
automatically adjusts to the desired limits based on the
current phase of flight (en route: 5.0 nm, terminal area:

1.0 nm, or approach: 0.3 nm). The desired GPS scale
settings may be selected manually on the MFD (refer to
the Multi Function Display section).

Bearing Pointers and Information Windows

Up to two bearing pointers can be displayed on the
HSI. Pressing the PFD softkey provides access to the
BRG1 and BRG2 softkeys. The BRG1 pointer is a single
cyan line with an open arrowhead at the end. The BRG2
pointer is a double cyan line with an open arrowhead at
the end. The bearing pointers never override the CDI.
When at least one bearing pointer is displayed (but not
necessarily visible if there is no data available), a white
ring appears around the center of the compass rose to
visually separate the bearing pointer(s) from the CDI.

When a bearing pointer is displayed, its associated
information window is also displayed.

Terrain Awareness and Warning System (TAWS)
is only available when the G1000 is configured for
TAWS-B installation. Class B TAWS provides these
principal alerting functions:

• Forward Looking Terrain Avoidance (FLTA) –
which looks ahead of the aircraft along and below
the aircraft’s lateral and vertical flight path and
provides alerts if a potential Controlled Flight into
Terrain (CFIT) threat exists

• Premature Descent Alert (PDA) – uses the aircraft’s
current position and flight path information as
determined from a suitable navigation source
and airport database to determine if the aircraft is
significantly below the normal approach path for
the destination runway

• Excessive Descent Rate Alert (EDR) – when the
aircraft is determined to be closing (descending)
upon terrain at an excessive speed

• Negative Climb Rate Alert (NCR) – when the
system detects the aircraft is losing altitude
(closing upon terrain) after takeoff

The FLTA and PDA features can be disabled to prevent
nuisance alerts while flying VFR into areas where unique
terrain exist and could cause the system to annunciate.

TAWS Alert Annunciations
