WARNINGS, CAUTIONS, AND NOTES
Warnings, Cautions, & Notes
Navigation and terrain separation must NOT be predicated
WARNING:
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 fl ight. The Terrain Proximity feature is only to be used
as an aid for terrain avoidance and is not certifi ed for use in applications
requiring a certifi ed 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.
The displayed minimum safe altitudes (MSAs) are only advisory
WARNING:
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.
The Garmin GDU 620 has a very high degree of functional
WARNING:
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 GDU 620. 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.
The altitude calculated by GPS receivers is geometric height
WARNING:
above Mean Sea Level and could vary signifi cantly from the altitude
displayed by pressure altimeters, such as the output from the GDC 74A
Air Data Computer, or other pressure altimeters in aircraft. GPS altitude
should never be used for vertical navigation. Always use pressure altitude
displayed by the GDU 620 PFD or other pressure altimeters in aircraft.
Do not use outdated database information. Databases used
WARNING:
in the G500 system 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 Pilots using an outdated database do so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.
