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 Diamond DA40, DA40F and DA40D 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 Pilots using an outdated database do so entirely at their own risk.
WARNING: The basemap (land and water data) must not be used for navigation, but rather only for non-navigational 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 Aeronautical Information
Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or giving an
intense radar echo.”
Garmin G1000 Pilot’s Guide For the Diamond DA40
190-00592-00 Rev. Aii
WARNINGS & CAUTIONS
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 and the G1000 Flight Manual Supplement. 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: 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.
CAUTION: The GDU 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 ANTIREFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free cloth and an eyeglass lens
cleaner that is specified as safe for anti-reflective coatings.

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
• GIA 63 – The GIA 63s are the central Integrated
Avionics Units (IAUs) of the G1000 System. The
IAUs serve as the main communications hub, linking
all LRUs with the PFD and the MFD displays. Each
IAU contains a GPS receiver, VHF COM/NAV/GS
receivers, and system integration microprocessors
and is paired with a GDU 1040 display through an
Ethernet connection. The IAUs do not communicate
with each other directly.
• GRS 77 – The GRS 77 is an Attitude and Heading
Reference System (AHRS) that provides aircraft atti
tude, heading, and vertical acceleration information
to the G1000. The unit contains advanced sensors,
accelerometers, and rate sensors and also uses inputs
from the Air Data Computer and Magnetometer
and GPS signals from the IAUs. AHRS operation is
discussed in 1.7 System Operation.
• GMU 44 – The GMU 44 Magnetometer measures
local magnetic field information. Data is sent to the
AHRS for processing to determine aircraft magnetic
heading. This unit receives power directly from the
AHRS and communicates with it using an RS-485
digital interface.
• GDC 74A – The GDC 74A Air Data Computer
(ADC) processes information received from the
pitot-static system and the outside air temperature
(OAT) sensor. The ADC provides pressure altitude,
airspeed, vertical speed, and OAT information to the
G1000 System and communicates with the IAUs,
displays, and AHRS through an ARINC 429 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 on the PFD at power-up. All system
annunciations should clear within the first minute of
power-up. The Audio Panel also annunciates all bezel
lights briefly upon power-up.
On the PFD, the AHRS system displays an ‘AHRS
ALIGN: Keep Wings Level’ message and begins to initialize.
The AHRS should display valid attitude and heading fields
within the first minute of power-up. The AHRS can align
itself while the aircraft is taxiing or during level flight.
NOTE: Refer to the approved Airplane Flight
Manual Supplement (AFMS) for specifi c
procedures concerning avionics power application
and emergency power supply operation.
NOTE: Refer to the Annunciations and Alerts
section for more information regarding system
annunciations and alerts.
NOTE: Refer to the Appendices for AHRS
initialization bank angle limitations.

SYSTEM OVERVIEW
1.6 DISPLAY BACKLIGHTING
NOTE: Refer to the Primary Flight Display section
for instructions on manually adjusting the
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. PFD, MFD, and Audio Panel
bezel/key lighting are normally controlled directly by the
existing instrument panel dimmer bus.
If desired, PFD and MFD display backlighting and
PFD, MFD, and Audio Panel bezel/key brightness can also
be adjusted manually. Audio Panel bezel/key brightness is
directly tied to MFD bezel/key adjustment.
1.7 SYSTEM OPERATION
NORMAL OPERATION
The PFD and MFD are connected together on a single
Ethernet bus, allowing for high-speed communication
between the two units. Each IAU is connected to a single
display, as shown in Figure 1-1. This allows the units to
share information, enabling true system integration.
In normal operating mode, the PFD displays
graphical flight instrumentation in lieu of traditional gyro
instruments. Attitude, heading, airspeed, altitude, and
vertical speed are all shown on one display (refer to the
PFD section for more information). The MFD shows a
full-color moving map with navigation information (refer
to the MFD section for a complete discussion of MFD
operation). Both displays offer control of COM and NAV
frequency selection, as well as heading, course/baro, and
altitude select functions. On the left of the MFD display,
the Engine Indication System (EIS) cluster shows engine
and airframe instrumentation (see the EIS section). The
following figure shows an example of normal G1000
System operation.

190-00592-00 Rev. AGarmin G1000 Pilot’s Guide for the Diamond DA40
1-11
SYSTEM OVERVIEW
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. Figure 1-7 shows an example of G1000
reversionary mode where the PFD has failed.
NOTE: The system alerts the pilot when backup
paths are utilized by the LRUs. Refer to the
Annunciations and Alerts section for further
information regarding these and other system
alerts.
If a display fails, the appropriate GIA 63-GDU 1040
Ethernet interface is cut off. Thus, the IAU 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 IAU are flagged as invalid on the
remaining display. The system reverts to backup paths for
the AHRS, ADC, Engine/Airframe Unit, and transponder,
as required. The change to backup paths is completely
automated for all LRUs and no pilot action is required.
If the system fails to detect a display problem,
reversionary mode may be manually activated by pressing
the Audio Panel’s red DISPLAY BACKUP button.
Pressing this button again deactivates reversionary mode.

AHRS MODES OF OPERATION
The GRS 77 Attitude and Heading Reference
System (AHRS) performs attitude, heading, and
vertical acceleration calculations for the G1000 System
utilizing GPS, Magnetometer, and air data in addition
to information from its internal sensors. Attitude and
heading information are updated on the PFD while the
AHRS receives appropriate combinations of information
from the external sensor inputs (see Figure 1-8).
Loss of GPS, Magnetometer, or air data inputs is
communicated to the pilot by message advisory alerts.
Any failure of the internal AHRS inertial sensors results
in loss of attitude and heading information (as indicated
by red ‘X” flags over the corresponding flight instruments
on the PFD).
NOTE: Refer to the Annunciations and Alerts
section for specific AHRS alert information.
GPS Input Failure
Two GPS inputs are provided to the AHRS. If GPS
information from one of the inputs fails, the AHRS uses
the remaining GPS input and an alert message is issued to
inform the pilot. If both GPS inputs fail, the AHRS can
continue to provide attitude and heading information to
the PFD as long as Magnetometer and airspeed data are
available and valid.
Magnetometer Failure
If the Magnetometer input fails, the AHRS continues to
output valid attitude information; however, the heading
output on the PFD is flagged as invalid with a red ‘X’.
Air Data Input Failure
Failure of the air data input has no effect on the AHRS
output while AHRS is receiving valid GPS information.
Invalid/unavailable airspeed data in addition to GPS failure
results in loss of all attitude and heading information.

SYSTEM OVERVIEW
1.8 CHECKLISTS (OPTIONAL)
The G1000 MFD is able to display electronic checklists
customized for the Diamond DA40. The G1000 accesses
the checklists from an SD card inserted into the bezel slot
(see Figure 1-3). Pressing the CHKLIST softkey allows
access to all checklists. Pressing the EXIT softkey exits
the Checklist pages and displays the page last viewed.
If the SD card contains a valid checklist file, the Powerup Page displays both the aircraft make and model to
which the checklist applies (DA40, DIAMOND AIRCRAFT
INDUSTRIES) and copyright information.
If the SD card contains an invalid checklist file or
no checklist, the Checklist Page displays ‘INVALID
CHECKLIST’ or ‘CHECKLIST NOT PRESENT’.
NOTE: Checklists cannot be edited from within the
system. Refer to the Garmin Aviation Checklist

please refer to the backup instruments.
This section describes the major features of the G1000
Primary Flight Display (PFD) as installed on Diamond
DA40, DA40F, and DA40D 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 “six-pack” of instruments 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 selec
tion 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, re
gardless of which seat the pilot is flying from, the aircraft
can be flown with one hand and the controls manipulated
with the other hand.
