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WARNING: Do not use outdated database information.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 Pilots using any outdated database do so entirely at their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