Steering to a waypoint
The
STEER
and
3-D STEER
screens help you steer precisely
along a course line to your active waypoint. Both screens
display—using large digits that you can read from a
distance—the following information:
• name of the active waypoint (if any)
• distance and bearing from your present position to the
active waypoint
• speed-over-ground (SOG) and course-over-ground (COG)
• estimated time of arrival (ETA) and estimated time
enroute (ETE)
• numerical and graphical XTE
In addition, the
3D STEER
screen, using a panoramic
perspective view, graphically displays your vessel in relation to
nearby waypoints, as well as avoidance points. Both screens
help guide you precisely along a course line; for example,
following a harbor channel, or a line between shoals and
sandbars, to an active waypoint. You can choose whichever
screen you prefer.
Of course, you can always access the information listed above
