Warnings, Cautions & Notes
WARNING: When installing the aera 660 , place the unit so it does not
™
obstruct the field of view or interfere with operating controls.
WARNING: The indicators represented on the Panel are based on GPS-derived
data and may differ from the instruments in the aircraft.
WARNING: Navigation and terrain separation must NOT be predicated upon
the use of the terrain function. The aera 660 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: 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 the GPS and GLONASS receivers is
geometric height above Mean Sea Level and could vary significantly from
the altitude displayed by pressure altimeters.
WARNING: Do not use outdated database information. Databases used in
the aera 660 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 Pilots using any outdated database do so entirely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 data link weather information for maneuvering in,
near, or around areas of hazardous weather. Information contained within
data link weather products may not accurately depict current weather
conditions.
