CAUTION
The GPS system is operated by the government of the United States which
is solely responsible for its accuracy and maintenance. The system is under
development and is subject to changes which could affect the accuracy and
performance of all GPS equipment. Although the GPS 55 AVD is a precision
electronic NAVigation AID (NAVAID), any NAVAID can be misused or
misinterpreted, and therefore become unsafe. Use the GPS 55 AVD at your
own risk. To reduce the risk, carefully review and understand all aspects of
this Owner's Manual and thoroughly practice operation using the simulator
mode prior to actual use. When in actual use, carefully compare indications
from the GPS 55 AVD to all available navigation sources including the
information from other NAVAIDs, visual sightings, charts, etc. For safety,
always resolve any discrepancies before continuing navigation.
The Jeppesen database incorporated in the GPS 55 AVD must be updated
regularly in order to ensure that its information is current. GARMIN issues
an update approximately every 28 days. Contact GARMIN or your local
GARMIN aviation dealer for more information on GPS 55 AVD database
updates. Pilots using an out-of-date database do so entirely at their own risk.
