Warnings, Cautions & Notes
WARNING: Navigation and terrain separation must NOT be predicated upon
the use of the terrain avoidance feature. The terrain avoidance 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 avoidance feature is only to be used as an aid for
terrain avoidance. 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 altitude calculated by G1000 GPS receivers is geometric
height above Mean Sea Level and could vary significantly from the altitude
displayed by pressure altimeters, such as the GDC 74B Air Data Computer,
or other altimeters in the aircraft. GPS altitude should never be used for
vertical navigation. Always use pressure altitude displayed by the G1000
PFD or other pressure altimeters in aircraft.
WARNING: Do not use outdated database information. Databases used in
the G1000 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 Pilots using any outdated database do so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 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 situational awareness.
WARNING: Do not rely solely upon the display of traffic information for
collision avoidance maneuvering. The traffic display does not provide collision
avoidance resolution advisories and does not under any circumstances or
conditions relieve the pilot's responsibility to see and avoid other aircraft.
