Reference
Highway Page
In this example, the high-
way page indicates that you
are off course to the right.
Steer left to get back on
course. Notice the emphasis
of the highway page is on
the desired course.
If you get too far off course,
a message box will appear
to indicate what course to
steer to get back on course
most efficiently.

Using the Highway Page
The GPS 45XL' s highway page also provides graphic
steering guidance to a destination, with a greater emphasis
on the straight-line desired course and the distance and
direction you are off course. The bearing and distance to a
waypoint, along with your current track and speed are dis-
played at the top of the screen, with your estimated time
enroute (ETE) and velocity made good (VMG, or the rate
you are closing in on your destination) at the bottom.

As you head toward your destination, the middle sec-
tion of the screen provides visual guidance to your way-
point on a moving graphic 'highway'. The moving arrow
just below the course deviation scale always points to your
selected waypoint relative to the direction you are moving.
Your present position is represented by the diamond in
the center of the course deviation scale. The line down the
middle of the highway represents your desired track. As
you navigate toward a waypoint, the highway will actually
move, indicating the direction you're off course, relative to
the position diamond on the CDI scale. To stay on course,
simply steer toward the center of the highway.
If you do get off the desired course by more than 1/5th
of the selected CDI range, the exact distance you are off
course will be displayed where the CDI scale setting nor-
mally appears (see the example at right). If you get too far
off course (the highway has disappeared), a message box
will appear to indicate what course to steer to get back on
course.
