Garmin G3X Pilot’s Guide
190-01115-00 Rev. K
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 ter-
rain 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WARNING: Do not use outdated database information.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 Pilots using any outdated database do so entirely at their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: Do not use data link weather information for maneuvering in,
near, or around areas of hazardous weather. Information contained with in
data link weather products may not accurately depict current weather condi-
tions.

Garmin G3X Pilot’s Guide
190-01115-00 Rev. K
Warnings, Cautions & Notes
WARNING: Do not use the indicated data link weather product age to
determine the age of the weather information shown by the data link weather
product. Due to time delays inherent in gathering and processing weather
data for data link transmission, the weather information shown by the data
link weather product may be significantly older than the indicated weather
product age.
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.
WARNING: The illustrations in this guide are only examples. Never use the
G3X to attempt to penetrate a thunderstorm. Both the FAA Advisory Circu-
lar, 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: Because of variation in the earth’s magnetic field, operating the
G3X within 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 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, informa-
tion presented by the G3X can be misused or misinterpreted and, therefore,
become unsafe.

Garmin G3X Pilot’s Guide
190-01115-00 Rev. K
Warnings, Cautions & Notes
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 situ-
ational 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 pres-
ent 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.
WARNING: Do not rely solely upon the display of traffic information for
collision avoidance maneuvering. The traffic display does not provide colli-
sion avoidance resolution advisories and does not under any circumstances
or conditions relieve the pilot’s responsibility to see and avoid other aircraft.
WARNING: Do not rely solely upon the display of traffic information to
accurately depict all of the traffic within range of the aircraft. Due to lack
of equipment, poor signal reception, and/or inaccurate information from
aircraft or ground stations, traffic may be present that is not represented on
the display.
WARNING: For safety reasons, G3X operational procedures must be learned
on the ground.
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. Unau-
thorized repairs or modifications could void both the warranty and the pilot’s
authority to operate this device under FAA/FCC regulations.

Garmin G3X Pilot’s Guide
190-01115-00 Rev. K
Warnings, Cautions & Notes
NOTE: The Garmin G3X has a very high degree of functional integrity. How-
ever, 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 cross-checking with all redundant or correlated
information available in the cockpit.
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.
