The GPS 150XL’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 or route is being navigated, the desti-
nation 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). The default setting of the CDI scale is 5.0 nm. If you are not navigating to a
destination, 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 150XL’s
turn anticipation and waypoint alert data during route operations (see Section 4).
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.
