3.1.3 Highway display
The highway display, shown in the combination display of radar/compass/highway and
plotter/compass/highway, 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 the 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.
