Garmin GPS 155XL TSO - Manual (Page 21)

The GPS 155XL’s NAV summary page provides you with the important informa-
tion needed to navigate directly to your destination. The destination field, located at
the bottom left of the page, displays the current destination waypoint or active route
leg being navigated. If no direct-to destination, route or approach is being navigated,
the destination field will remain blank.
The graphical CDI (course deviation indicator) at the top of the page shows your
position relative to the desired course (the moving D-bar) to the destination way-
point. The TO/FROM arrow in the center of the scale indicates whether you are
heading to (an up arrow) the waypoint or if you have passed the waypoint (a down
arrow). Note that the GPS 155XL always navigates TO a waypoint unless the GPS
SEQ switch is set to the HOLD position, or you have passed the last waypoint in a
route. The default setting of the CDI scale is ‘Auto’. If you are not navigating to a des-
tination, the CDI field will display a ‘No active waypoint’ message, and only speed
and track data will be available. The CDI field is also used to display the GPS 155XL’s
turn anticipation and waypoint alert data during route and approach operations (see
sections 4 and 5).
In addition to displaying your active destination and the course deviation scale,
the NAV summary page features five selectable fields for various distance, direction,
speed and time options. This allows you to configure the NAV summary page to your
preferences. The default settings displayed are distance, ground speed, bearing,
desired track and estimated time enroute.
