Highway display

The highway display, displayed at the lower half of the screen in the combination
display, provides a graphic presentation of ship's track along intended course. It
is useful for monitoring ship's progress toward a waypoint. The own ship marker
shows relation between ship and intended course. The XTE monitor shows the
direction and amount your vessel is off course – the arrow shows the direction to
steer to return to your course and the numeric the distance you are off course.
Using the figure below as an example, you would steer right 0.009 nm to return
to course. To maintain course, steer the vessel so the own ship marker stays
aligned with the intended course line.
