Reading the XTE (cross-track error) monitor
The XTE monitor, located below the compass rose, shows the distance you are off course
and the direction to steer to return to course. The own ship marker moves according to
direction and distance off course. It is shown in black when the amount of cross-track error
is within the XTE monitor range and yellow when it is over. An arrow appears at the right or
left side of the XTE monitor and it shows the direction to steer to return to intended course.
It is shown in red when you should steer left, and green when you should steer right. In the
example on the previous page you would steer right to return to course. To maintain course,
steer the vessel so the own ship marker stays at the center of the XTE monitor.
