WARNINGS, CAUTIONS, AND NOTES
Warnings, Cautions, & Notes
WARNING: Navigation and terrain separation must NOT be predicated
upon the use of the terrain function. The GDU 620 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 warning system. Terrain data is
obtained from third party sources. Garmin is not able to independently
verify the accuracy of the terrain data.
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 Garmin G500/G600 systems have 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 G500/G600. 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.
WARNING: The altitude calculated by GPS receivers is geometric height
above Mean Sea Level and could vary significantly from the altitude
displayed by pressure altimeters, such as the output from the GDC 74A/74B
Air Data Computer, or other altimeters in aircraft. GPS altitude should never
be used for vertical navigation. Always use pressure altitude displayed by
the G500/G600 PFD or other pressure altimeters in aircraft.
WARNING: Do not use outdated database information. Databases used
in the G500/G600 systems must be updated regularly in order to ensure
that the information remains current. Pilots using an outdated database
do so entirely at their own risk.
