Garmin G1000 Pilot’s Guide for Cessna Nav III
190-00498-07 Rev. Aii
WARNINGS, CAUTIONS, AND 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 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WARNING: Do not use outdated database information.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 Pilots using any outdated database do so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: Traffic information shown on system displays is provided as an aid in visually acquiring traffic.
Pilots must maneuver the aircraft based only upon ATC guidance or positive visual acquisition of conflicting
traffic.
WARNING: Use of the Stormscope is not intended for hazardous weather penetration (thunderstorm
penetration). Stormscope information, as displayed on the G1000 MFD, is to be used only for weather
avoidance, not penetration.
WARNING: Do not use datalink weather products (e.g., XM WX Satellite Weather, GFDS World Wide Weather,
or FIS-B) for hazardous weather penetration. Weather information provided by these products is aged by up
to several minutes and may not depict actual weather conditions as they currently appear.
WARNING: NEXRAD weather data is to be used for long-range planning purposes only. Due to inherent
delays in data transmission and the relative age of the data, NEXRAD weather data should not be used for
short-range weather avoidance.
