WARNINGS, CAUTIONS, AND NOTES
WARNING:
Do not use GPS to navigate to any active waypoint identified as a ‘NON WGS84 WPT’ by a
system message. ‘NON WGS84 WPT’ waypoints are derived from an unknown map reference datum that
may be incompatible with the map reference datum used by GPS (known as WGS84) and may be positioned
in error as displayed.
WARNING:
When using the autopilot to fly an approach with vertical guidance, the autopilot will not level
the aircraft at the MDA/DH even if the MDA/DH is set in the altitude preselect.
CAUTION:
Do not clean display surfaces with abrasive cloths or cleaners containing ammonia. They will
harm the anti-reflective coating.
CAUTION:
Repairs should only be made by an authorized Garmin service center. Unauthorized repairs or
modifications could void both the warranty and affect the airworthiness of the aircraft.
NOTE:
Do not rely solely upon data link services to provide Temporary Flight Restriction (TFR) information.
Always confirm TFR information through official sources such as Flight Service Stations or Air Traffic Control.
NOTE:
All visual depictions contained within this document, including screen images of the system panel
and displays, are subject to change and may not reflect the most current system and aviation databases.
Depictions of equipment may differ slightly from the actual equipment.
NOTE:
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 system use GPS as a precision electronic NAVigation
AID (NAVAID). Therefore, as with all NAVAIDs, information presented by the system can be misused or
misinterpreted and, therefore, become unsafe.
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
:
Interference from GPS repeaters operating inside nearby hangars can cause an intermittent loss of
attitude and heading displays while the aircraft is on the ground. Moving the aircraft more than 100 yards
away from the source of the interference should alleviate the condition.
NOTE
:
Use of polarized eyewear may cause the flight displays to appear dim or blank.
NOTE
:
This product, its packaging, and its components contain chemicals known to the State of California
to cause cancer, birth defects, or reproductive harm. This notice is being provided in accordance with
California’s Proposition 65. If you have any questions or would like additional information, please refer to
our web site at www.garmin.com/prop65.

WARNINGS, CAUTIONS, AND NOTES
NOTE:
Operating the system in the vicinity of metal buildings, metal structures, or electromagnetic fields
can cause sensor differences that may result in nuisance miscompare annunciations during start up, shut
down, or while taxiing. If one or more of the sensed values are unavailable, the annunciation indicates no
comparison is possible.
NOTE:
The system responds to a terminal procedure based on data coded within that procedure in the
Navigation Database. Differences in system operation may be observed among similar types of procedures
due to differences in the Navigation Database coding specific to each procedure.
NOTE
:
The FAA has asked Garmin to remind pilots who fly with Garmin database-dependent avionics of the
following:
• It is the pilot’s responsibility to remain familiar with all FAA regulatory and advisory guidance and information
related to the use of databases in the National Airspace System.
• Garmin equipment will only recognize and use databases that are obtained from Garmin or Jeppesen. Databases
obtained from Garmin or Jeppesen that have a Type 2 Letter of Authorization (LOA) from the FAA are assured
compliance with all data quality requirements (DQRs). A copy of the Type 2 LOA is available for each applicable
database and can be viewed at http://fly.garmin.com by selecting ‘Aviation Database Declarations.’
• Use of a current Garmin or Jeppesen database in your Garmin equipment is required for compliance with
established FAA regulatory guidance, but does not constitute authorization to fly any and all terminal procedures
that may be presented by the system. It is the pilot’s responsibility to operate in accordance with established
POHs and regulatory guidance or limitations as applicable to the pilot, the aircraft, and installed equipment.
NOTE
:
The pilot/operator must review and be familiar with Garmin’s database exclusion list as discussed in
SAIB CE-14-04 to determine what data may be incomplete. The database exclusion list can be viewed at
www.flygarmin.com by selecting ‘Database Exclusions List.’
NOTE
:
The pilot/operator must have access to Garmin and Jeppesen database alerts and consider their
impact on the intended aircraft operation. The database alerts can be viewed at www.flygarmin.com by
selecting ‘Aviation Database Alerts.’
NOTE
:
If the pilot/operator wants or needs to adjust the database, contact Garmin Product Support.
NOTE:
Garmin requests the flight crew report any observed discrepancies related to database information.
These discrepancies could come in the form of an incorrect procedure; incorrectly identified terrain, obstacles
and fixes; or any other displayed item used for navigation or communication in the air or on the ground. Go
to FlyGarmin.com and select ‘Aviation Data Error Report’.
NOTE:
(EFB) electronic aeronautical chart applications. Possible additional requirements may make a secondary
source (traditional paper or additional electronic display) necessary onboard the aircraft. If the secondary
source is a Portable Electronic Device (PED), its use must be consistent with guidance in AC 120-76C.

OVERVIEW
SYSTEM
1.1 SYSTEM DESCRIPTION
INSTRUMENTS
This section provides an overview of the G1000 NXi Integrated Avionics System as installed in the Cessna
Nav III. The system presents flight instrumentation, position, navigation, communication, and identification
information to the pilot through large-format displays.
The optional Flight Stream 510 device provides a Bluetooth® connection between the system and a mobile
EIS
device. GPS, ADAHRS/AHRS, ADS-B, traffic, SiriusXM audio, and weather data can then be shared with the
mobile device, and flight plans can be transferred to or from the mobile device. Also, database updates may also
be performed using the Flight Stream 510 WiFi link.
LINE REPLACEABLE UNITS (LRU)
& CNS
The system consists of the following Line Replaceable Units (LRUs):
•
GDU 1050
(1) – The GDU 1050 is configured as a Primary Flight Display (PFD). The display communicates
MANAGEMENT
with the MFD and with the #1 GIA 63W Integrated Avionics Unit through a High-Speed Data Bus (HSDB)
Ethernet connection.
•
GDU 1054
(1) – The GDU 1054 is configured as an MFD. The display communicates with the PFD and with
the #2 GIA 63W Integrated Avionics Unit through a High-Speed Data Bus (HSDB) Ethernet connection.
•
GIA 63W
(2) – Functions as the main communication hub, linking all LRUs with the PFD and MFD. Each
AVOIDANCE
GIA 63W contains a GPS SBAS receiver, VHF COM/NAV/GS receivers, a flight director (FD) and system
integration microprocessors. Each GIA 63W is paired with the PFD and MFD via HSDB connection. The
GIA 63Ws are not paired together and do not communicate with each other directly.

•
GSU 75
(1) – Processes data from the pitot/static system as well as the OAT probe to provide pressure
altitude, airspeed, vertical speed and OAT information to the system. This unit also provides aircraft attitude
and heading information via ARINC 429 to the PFD, MFD, and GIA 63W. The GSU 75 contains advanced
sensors (including accelerometers and rate sensors) and interfaces with the GMU 44 to obtain magnetic field
information, and with the GIA 63W to obtain GPS information. ADAHRS/AHRS modes of operation are
discussed later in this document.
•
GDC 72 / 74A
(1) (Optional) – Processes data from the pitot/static system as well as the OAT probe. This unit
provides pressure altitude, airspeed, vertical speed and OAT information to the system, and it communicates
with the GIA 63Ws, the displays, and the GRS 77/79, using an ARINC 429 digital interface (it also interfaces
directly with the GTP 59). The GDC 74A is designed to operate in Reduced Vertical Separation Minimum
(RVSM) airspace.
•
GRS 77 / 79
(1) (Optional) – Provides aircraft attitude and heading information via ARINC 429 to both
displays and both GIA 63Ws. The GRS 77/79 contains advanced sensors (including accelerometers and rate
sensors) and interfaces with the GMU 44 to obtain magnetic field information, with the GDC 74A to obtain
air data, and with both GIA 63/63Ws to obtain GPS information. AHRS modes of operation are discussed

In addition to using internal sensors, the GSU 75 ADAHRS uses GPS information, magnetic field data and
air data to assist in attitude/heading calculations. In normal mode, the ADAHRS relies upon GPS and magnetic
field measurements. If either of these external measurements is unavailable or invalid, the ADAHRS uses air
data information for attitude determination. Eight ADAHRS modes of operation are available (see Table 1-1)
and depend upon the combination of available sensor inputs. Loss of air data, GPS, or magnetometer sensor
inputs is communicated to the pilot by system messages.

FLIGHT
Aggressive maneuvering while AHRS is not operating normally may degrade AHRS accuracy.
In addition to using internal sensors, the AHRS uses GPS information, magnetic field data and air data
to assist in attitude/heading calculations. In normal 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 and depend upon the
EIS
combination of available sensor inputs. Loss of air data, GPS, or magnetometer sensor inputs is communicated
to the pilot by message advisory alerts.
The AHRS corrects for shifts and variations in the Earth’s magnetic field by applying the Magnetic Field
Variation Database. The Magnetic Field Variation Database is derived from the International Geomagnetic
AUDIO PANEL
& CNS
Reference Field (IGRF). The IGRF is a mathematical model that describes the Earth’s main magnetic field and its
annual rate of change. The database is updated approximately every 5 years. See the Appendices for information
on updating the Magnetic Field Variation Database. The system will prompt you on startup when an update is
available. Failure to update this database could lead to erroneous heading information being displayed to the

SYSTEM OVERVIEW
GPS INPUT FAILURE
SYSTEM
OVERVIEW
NOTE:
true air speed values greater than approximately 200 knots, is not guaranteed. Under these rare conditions,
it is possible for in-flight ADAHRS/AHRS initialization to take an indefinite amount of time which would
result in an extended period of time where valid ADAHRS/AHRS outputs are unavailable.
FLIGHT
INSTRUMENTS
The 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 ADAHRS/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
EIS
inputs fail, the ADAHRS/AHRS continues to operate in reversionary No-GPS mode so long as the air data and
magnetometer inputs are available and valid.

FEATURES
ADDITIONAL
A failure of the air data input has no effect on ADAHRS/AHRS output while ADAHRS/AHRS is operating in
normal mode. A failure of the air data input while the ADAHRS/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 ADAHRS/AHRS transitions to one of the reversionary No-Magnetometer
modes and continues to output valid attitude information. However, if the aircraft is airborne, the heading
output on the PFD does become invalid (as indicated by a red “X”).
GPS RECEIVER OPERATION
Each GIA 63W Integrated Avionics Unit (IAU) contains a GPS receiver. Information collected by the specified
receiver (GPS1 for the #1 IAU or GPS2 for the #2 IAU) may be viewed on the Aux - GPS Status Page.
These GPS sensor annunciations are most often seen after system power-up when one GPS receiver has
acquired satellites before the other, or one of the GPS receivers has not yet acquired a SBAS signal. While
the aircraft is on the ground, the SBAS signal may be blocked by obstructions causing one GPS receiver to
have difficulty acquiring a good signal. Also, while airborne, turning the aircraft may result in one of the GPS
receivers temporarily losing the SBAS signal.
If the sensor annunciation persists, check for a system failure message in the Messages Window on the PFD.
If no failure message exists, check the GPS Status Page and compare the information for GPS1 and GPS2.
Discrepancies may indicate a problem.
