Garmin GPS 155TSO, Owner'S Manual

Page: 18 / 132

If the GPS 155 is not currently navigating to a
waypoint, ‘No actv wpt’ will be displayed in the
CDI field.
The GPS 155’s CDI page provides you with the important information 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 navi-
gated. If no direct-to destination, route or approach is being navigated, the destina-
tion field will display a dashed leg (____
È
_____).
The graphical CDI at the top left of the page shows your position relative to the
desired course (the moving D-bar) to the destination waypoint. The TO/FROM
arrow in the center of the scale indicates whether you are heading to (an up arrow)
the waypoint or from the waypoint (a down arrow). Note that the GPS 155 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
5.0 nm. The CDI field is also used to display the GPS 155’s turn anticipation and
waypoint alert data during route and approach operations (See sections 3 and 4). In
addition to displaying your active destination and the course deviation indicator, the
CDI page features four selectable fields for various distance, direction and time
options. This allows you to configure the CDI page to your preferences. The default
settings displayed are ground speed, distance, track and estimated time enroute.
