Database Confirmation Page
Welcome Page
The GARMIN GNC 250 is a powerful navigational tool that provides pilots with accurate navi-
gational data and communication capability, along with a host of database information at your fin-
gertips. The Takeoff Tour is designed to familiarize you with the operation of the GNC 250,
including powering up the unit, changing frequencies, entering data and performing a simple
direct-to, and a limited introduction to the ‘Nearest’ functions. In addition, this section also briefly
covers the position, CDI 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 GPSCOM
TM
and antennas have been properly
installed and you have not changed any of the GNC 250’s default settings. If you have
changed any of the factory default settings (position format, units of measure, selectable
fields, etc.), the pictures used may not match your configuration. Prior to using your GNC
250 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 GNC 250
The GNC 250’s power and volume are controlled using the
B
(power/volume) knob
at the bottom left of the unit. Rotating it clockwise will turn the unit on and increase the
radio volume. After turning the unit on, a welcome page will be displayed while the unit
performs a self test.
The database page will appear, showing the current database information on the NavData
card, with the valid operating dates, cycle number and database type indicated. Databases are
updated every 28 days and are available for one-time or subscription purchase.
To acknowledge the database information:
