Pointer to Wajipoini
The line down the middle of the graphic high­
way represents your desired track (a straight line
between the position you started from to the
selected waypoint), with your present position
indicated hy the diamond in the center of the
course devition scale. The arrow pointer below the
highway serves as a relative bearing pointer to
your destination waypoint.
As you navigate toward a waypoint, the high­
way will actually move, indicating the direction
you’re off course, relative to the position diamond
on the GDI scale. To keep your vessel on the
desired course, simply steer toward the center of
the hi^way.
If you do get off the desired course by more
than l/5th of the selected GDI range, the exact
distance you are off course will be displayed where
the GDI scale setting normally appears (see the
example at left). As you approach a waypoint, a
horizontal ‘finish line’ will move toward the bot­
tom of the highway. When the finish line reaches
the GDI scale, you’ve arrived at your destination.
