WARNING:
function. The G1000 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:
relied upon as the sole source of obstacle and terrain avoidance information. Always refer to current
aeronautical charts for appropriate minimum clearance altitudes.
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 G1000. 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:
and could vary significantly from the altitude displayed by pressure altimeters, such as the GDC 74A
Air Data Computer, or other altimeters in 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:

packet is included in the G1000 package. Pilots using an outdated database do so entirely at their own
risk.
