Garmin GPS 155XL TSO - Manual (Page 11)

The GARMIN GPS 155XL is a powerful navigational tool that provides pilots with accurate
navigational data, including non-precision approaches, SIDs and STARs. The Takeoff Tour is
designed to familiarize you with the operation of the GPS 155XL, including powering up the unit,
entering data and performing a simple direct-to, and provide a limited introduction to the
‘Nearest’ functions. In addition, this section also briefly covers the position, NAV summary, map
and frequency pages available from the NAV key. These pages will be used for most of your in-
flight navigation.
The Takeoff Tour assumes that the receiver and antenna have been properly installed
and you have not changed any of the GPS 155XL’s default settings. If you have changed
any of the factory default settings (position format, units of measure, selectable fields, etc.),
the pictures shown here may not match your configuration. Prior to using your GPS
155XL for the first time, we recommend that you taxi to a location that is well away from
buildings and other aircraft so the unit can collect satellite data without interruption.
Powering up the GPS 155XL
The GPS 155XL’s power and display intensity are controlled using the B knob at the
bottom left of the unit. Rotating it clockwise will turn unit power on and progressively
increase the display intensity. After turning the unit on, a welcome page will be displayed
while the unit performs a self test.
The database page will appear next, showing the current database information on the
NavData card, with the valid operating dates, cycle number and database type indicated. The
database is updated every 28 days, and must be current for approved approach and IFR opera-
tions. Information on database subscriptions is available inside your GPS 155XL package.
To acknowledge the database information:
1. Press the
E

The database confirmation page shows the
effective and expiration dates of the Jeppesen
database on the NavData Card.
The welcome page appears when the GPS 155XL
is turned on. During the time this screen is
displayed, the GPS 155XL performs a self test to
ensure proper operation.
