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WARNING: Do not use outdated database information.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 Pilots using any outdated database do so entirely at their own risk.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: SiriusXM 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.
