Garmin GPS 155XL TSO - Manual (Page 4)

CAUTION
The Global Positioning System is operated by the United States government,
which is solely responsible for its accuracy and maintenance. The system is subject to
changes which could affect the accuracy and performance of all GPS equipment.
Although the GARMIN GPS 155XL is a precision electronic NAVigation AID
(NAVAID), any NAVAID can be misused or misinterpreted and therefore become
unsafe.
Use the GPS 155XL at your own risk. To reduce the risk of unsafe operation,
carefully review and understand all aspects of this Owner’s Manual and the Flight
Manual Supplement, and thoroughly practice using the simulator mode prior to actu-
al use. When in actual use, carefully compare indications from the GPS 155XL 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 altitude calculated by the GPS 155XL is geometric height above mean sea
level and could vary significantly from altitude displayed by pressure altimeters in air-
craft. Never use GPS altitude for vertical navigation.
The Jeppesen database incorporated in the GPS 155XL must be updated regularly
in order to ensure that its information is current. Updates are released every 28 days.
A database information packet is included in your GPS 155XL package.
Pilots using an out-of-date database do so entirely at their own risk.
