Warnings, Cautions & Notes
WARNING: Navigation and terrain separation must NOT be predicated upon the
use of the terrain function. The G3X 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: To reduce the risk of unsafe operation, carefully review and understand
all aspects of the G3X Pilot’s Guide documentation and the Pilot’s Operating
Handbook of the aircraft. Thoroughly practice basic operation prior to actual use.
During flight operations, carefully compare indications from the G3X 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.
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 altitude calculated by G3X internal GPS receivers is geometric height
above Mean Sea Level and could vary significantly from the altitude displayed by
pressure altimeters. Always use pressure altitude displayed by the G3X PFD when
determining or selecting aircraft altitude.
WARNING: Do not use outdated database information. Databases used in the G3X
system must be updated regularly in order to ensure that the information remains
current. Pilots using any outdated database do so entirely at their own risk.
WARNING: XM Weather should not be used for hazardous weather penetration.
Weather information is approved only for weather avoidance, not penetration.
WARNING: NEXRAD weather data is to be used for long-range planning purposes
only. Due to inherent delays in data transmission and the relative age of the data,
NEXRAD weather data should not be used for short-range weather avoidance.
WARNING: The data contained in the terrain and obstacle databases comes from
government agencies. Garmin accurately processes and cross-validates the data,
but cannot guarantee the accuracy and completeness of the data.

Warnings, Cautions & Notes
WARNING: The illustrations in this guide are only examples. Never use the G3X
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.”
WARNING: For safety reasons, G3X operational procedures must be learned on
the ground.
WARNING:
the following areas could result in loss of reliable attitude and heading indications. North
of 72° North latitude at all longitudes; South of 70° South latitude at all longitudes;
North of 65° North latitude between longitude 75° W and 120° W. (Northern Canada);
North of 70° North latitude between longitude 70° W and 128° W. (Northern Canada);
North of 70° North latitude between longitude 85° E and 114° E. (Northern Russia);
South of 55° South latitude between longitude 120° E and 165° E. (Region south of
Australia and New Zealand)
WARNING: The Garmin G3X 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 G3X. It is
thus the responsibility of the pilot to detect such an occurrence by means of crosschecking with all redundant or correlated information available in the cockpit.
Because of variation in the earth’s magnetic field, operating the G3X within
WARNING: 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 G3X utilize GPS as a precision electronic NAVigation AID
(NAVAID). Therefore, as with all NAVAIDs, information presented by the G3X can
be misused or misinterpreted and, therefore, become unsafe.
WARNING: Do not use basemap (land and water data) information for primary
navigation. Basemap data is intended only to supplement other approved
navigation data sources and should be considered as an aid to enhance situational
awareness.
WARNING: Do not use the approach information provided by the VFR navigation
database residing within the G3X as a means of navigating any instrument
approach. The G3X VFR navigation database is limited to present only the waypoints
for the final approach leg of a published procedure. These waypoints and associated
course line are made available for monitoring purposes only.

Warnings, Cautions & Notes
CAUTION: The display uses 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, lint-free cloth and an eyeglass lens cleaner that is
specified as safe for anti-reflective coatings.
CAUTION: The Garmin G3X 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.
NOTE: All visual depictions contained within this document, including screen images
of the G3X panel and displays, are subject to change and may not reflect the most
current G3X system and aviation databases. Depictions of equipment may differ
slightly from the actual equipment.
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.
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: Temporary Flight Restriction (TFR) data is provided by the FAA and may
not be updated outside of normal business hours. Confirm data currency through
alternate sources and contact your local FSS for interpretation of TFR data.
NOTE: The Garmin G3X system includes products like the GDU 37X and the GSU
73 that are not TSO-certified products and have not received FAA approval or
endorsement. Consequently the G3X system is not suitable for installation in
type-certificated aircraft.

System Overview
Ch a n g i n g t h e na v i g a t i o n So u r C e
Overview
When an external navigator that supports both GPS and VOR/ILS capabilities (i.e.,
GNS 430/530) is selected, the external navigator’s CDI Key is used to switch the G3X
Instruments EIS
HSI between GPS and VOR/ILS navigation.
Se l e C t i o n Be t w e e n Mu l t i p l e na v i g a t o r S
The G3X CDI SRC Softkey (refer to Section 1.7) becomes available when more than
one source of navigation data is configured. The CDI SRC Softkey toggles between
the available navigation sources (e.g., between the internal G3X GPS and external
Interface
SL30 VLOC sources, between an SL30 and a GNS 430, or between two GNS 430s, etc).
Refer to the Flight Instruments section for more information.

Hazard
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 (indicated by red ‘X’ flags over the corresponding
flight instruments).
If GPS input fails, the AHRS can continue to provide attitude and heading information
to the PFD as long as magnetometer and airspeed data are available and valid.
If the magnetometer input fails, the AHRS continues to output valid attitude
information; however, the heading output on the PFD Page is flagged as invalid with
a red ‘X’.
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. Likewise, loss of magnetometer
(heading) data, in combination with loss of GPS data results in a loss of all attitude
and heading information.

DATA ENTRY
The FMS Joystick can be used for directly entering alphanumeric data into the G3X.
In some instances, such as when entering an identifier, the G3X tries to predict the
desired identifier based on the characters being entered. In this case, if the desired
identifier appears, use the ENT Key to confirm the entry without entering the rest of
the identifier manually. This can save the pilot from having to enter all the characters
of the identifier.
Besides character-by-character data entry, the system also provides a shortcut
for entering waypoint identifiers. When the cursor is on a field awaiting entry of a
waypoint identifier, turning the FMS Joystick counter-clockwise accesses a menu
with three different lists of identifiers for quick selections: recent waypoints (RECENT
WPTS), nearest airports (NRST APTS), and flight plan waypoints (FPL WPTS). The G3X
automatically fills in the identifier, facility, and city fields with the information for the
selected waypoint.

accurate data to the GDU(s).
The Dual Display System can be configured to share GPS information (refer to the
G3X Installation Manual for configuration information). For example, a GDU can be
configured to share its GPS position, velocity, and time data with another GDU. If a
GDU is not using its own GPS receiver, the name of the GDU providing the data (i.e.,

Satellites currently in view are shown at their respective positions on a satellite
constellation diagram. The outer circle of the constellation diagram represents the
horizon, the inner circle represents 45° above the horizon, and the center point shows
the position directly overhead. Each satellite is represented by a square containing the
Pseudo-Random Noise (PRN) number (i.e., satellite identification number).

System Overview
The INFO Page can be helpful in troubleshooting weak (or missing) signal levels
due to poor satellite coverage or installation problems. As the GPS receiver locks
onto satellites, a signal strength bar is displayed for each satellite in view, with the
appropriate satellite PRN number (01-32 or 33-64 for WAAS) below each bar. The
progress of satellite acquisition is shown in three stages, as indicated by signal bar
appearance:
- No bar—Receiver is looking for the indicated satellite
- Gray bar—Receiver has collected the necessary data and the satellite signal can
be used
- Green bar—Satellite is being used for the GPS solution
POSITION
The Position box on the INFO Page displays latitude, longitude, accuracy (in feet),
reference waypoint, type, distance, direction, and bearing. The reference waypoint is
designed to display the current position in relation to a prominent landmark. The pilot
can change the reference waypoint ‘Nearest Type’ using the ‘Change Nearest Type’
page menu option. By default the Nearest Type is set to ‘Automatic’, which will display
the nearest large airport, enroute VOR, or city (in that order).

AIRSPEED INDICATOR
NOTE:
The Airspeed Indicator displays airspeed on a rolling number gauge using a moving
tape. The true airspeed (TAS) is displayed in knots below the Airspeed Indicator. The
numeric labels and major tick marks on the moving tape are marked at intervals of 10
knots. Speed indication starts at 20 knots, with 60 knots of airspeed viewable at any
time. The actual airspeed is displayed inside the black pointer. The pointer remains
black until reaching never-exceed speed (VNE), at which point it turns red.
A color-coded (red, white, green, yellow, and red/white “barber pole”) speed range
strip is located on the moving tape. The colors denote flaps operating range, normal
operating range, caution range, and never-exceed speed (VNE). A red range is also
present for low speed awareness.
The Airspeed Trend Vector is a vertical, magenta line, extending up or down on the
airspeed scale, shown to the right of the color-coded speed range strip. The end of
the trend vector corresponds to the predicted airspeed in 6 seconds if the current rate
of acceleration is maintained. If the trend vector crosses VNE, the text of the actual
airspeed readout changes to yellow. The trend vector is absent if the speed remains
constant or if any data needed to calculate airspeed is not available due to a system
failure.
The G3X Vspeed Reference values and Flaps Tick Mark values depend
upon the aircraft’s specific system configuration and may vary from the
examples discussed in this section.

BEARING POINTERS AND INFORMATION WINDOWS
Two bearing pointers and associated information can be displayed on the HSI for NAV
and GPS sources. The bearing pointers are light blue and are single-line (Bearing Pointer
1) or double-line (Bearing Pointer 2). A pointer symbol is shown in the information
windows to indicate the navigation source. The bearing pointers never override the
CDI and are visually separated from the CDI by a white ring (shown when the bearing
pointers are selected but not necessarily visible due to data unavailability).
When a bearing pointer is displayed, its associated information window is also
displayed. The Bearing Information Windows are displayed at the lower sides of the HSI.
The following information may be displayed in the Bearing Information Windows:
•Bearingsource(NAV,GPS)
• Pointer icon (single lined or double
lined)
•Frequency(NAV)
If an external NAV radio is the bearing source and it is tuned to an ILS frequency,
the bearing source and the bearing pointer is removed from the HSI and the frequency
is replaced with “ILS”. When VLOC1 or VLOC2 is the selected bearing source, the
frequency is replaced by the station identifier when the station is within range. If GPS
is the bearing source, the active waypoint identifier is displayed in lieu of a frequency.
The bearing pointer is removed from the HSI and “NO DATA” is displayed in the

COURSE DEVIATION INDICATOR (CDI)
The HSI contains a Course Deviation Indicator (CDI), with a Course Pointer, To/From
Indicator, and a sliding deviation bar and scale. The course pointer is a single line
arrow (GPS1, VOR1, and LOC1) or a double line arrow (GPS2, VOR2, and LOC2) which
points in the direction of the set course. The To/From arrow rotates with the course
pointer and is displayed when the active NAVAID is received.
The Course Deviation Indicator (CDI) moves left or right from the course pointer
along a lateral deviation scale to display aircraft position relative to the course. If the
course deviation data is not valid, the CDI is not displayed.
Another Lateral Deviation Scale and combination Course Deviation and To-From
Indicator is located below the slip/skid indicator.

The CDI is capable of displaying two sources of navigation: GPS or NAV (VOR,
localizer) depending on the external navigator(s) configured (refer to the G3X
Installation Manual for more information). Color indicates the current navigation
source: magenta (for GPS) or green (for VOR and LOC). The full-scale limits for the CDI
are defined by a GPS-derived distance when coupled to GPS. When coupled to a VOR
or localizer (LOC), the CDI has the same angular limits as a mechanical CDI. If the
CDI exceeds the maximum deviation on the scale (two dots) while coupled to GPS, the
crosstrack error (XTK) is displayed below the white aircraft symbol.

NOTE:
The pilot should follow the engine manufacturer’s recommended

A LEAN Softkey is displayed on the ENG Page if Lean Assist Mode is enabled and
at least one Exhaust Gas Temperature (EGT) or Turbine Inlet Temperature (TIT) input is
configured (refer to the G3X Installation Manual for more information).
Using Lean Assist Mode:
From the ENG Page, press the LEAN Softkey. As the mixture is leaned, one of
the cylinder’s exhaust temperature will peak. Continuing to lean the mixture
will cause each additional cylinder to peak (if applicable) until the last of the
cylinders peaks. To cancel Lean Assist Mode, press the LEAN Softkey again.

If a fuel flow sensor is configured, the fuel flow value detected as the first cylinder

fuel flow gauge as a hollow blue pointer. This can be used to determine if you are on
the rich side of peak (ROP) or the lean side of peak (LOP). Rich of Peak (ROP) if the fuel
flow pointer is above the blue triangle, or Lean of Peak (LOP) if the fuel flow pointer is
below the blue triangle.

from the responsibility of proper flight planning. G3X fuel calculations do not
use the aircraft fuel quantity indicators and are calculated from the last time
the fuel was reset.
NOTE:
An optional Fuel Flow Sensor must be configured for the FUEL Softkey
to appear on the ENG Page. Refer to the Installation Manual for more
information.
