Garmin aera 500 Series Pilot’s Guide 190-01117-02 Rev. A
warnings, cautions & Notes
WARNING: The illustrations in this guide are only examples. Never use the
aera to attempt to penetrate a thunderstorm. Both the FAA Advisory Circular,
Subject: Thunderstorms, and the Aeronautical Information Manual (AIM)
recommend avoiding “by at least 20 miles any thunderstorm identified as
severe or giving an intense radar echo.”
WARNING: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the aera Pilot’s Guide documentation and the Pilot’s
Operating Handbook of the aircraft. Thoroughly practice basic operation
prior to actual use. During flight operations, carefully compare indications
from the aera to all available navigation sources, including the information
from other NAVAIDs, visual sightings, charts, etc. For safety purposes, always
resolve any discrepancies before continuing navigation.
WARNING: The Garmin aera has a very high degree of functional 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 aera. 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: For safety reasons, aera operational procedures must be learned
on the ground.
WARNING: The United States government operates the Global Positioning
System and is solely responsible for its accuracy and maintenance. The GPS
system is subject to changes which could affect the accuracy and performance
of all GPS equipment. Portions of the Garmin aera utilize GPS as a precision
electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs,
information presented by the aera can be misused or misinterpreted and,
therefore, become unsafe.
WARNING: The data contained in the terrain and obstacle databases comes
from government agencies. Garmin accurately processes and cross-validates
the data, but cannot guarantee the accuracy and completeness of the data.
