Screen Group 4: Nav 1
There are six screens in this group. Only screen 3 has a sub-
screen.
Screen 1
WAYPOINT ID
•
The upper screen section displays the destination waypoint
I.D.
•
The lower screen section is empty.
Screen 2
CROSS TRACK ERROR
•
The upper screen section displays ‘XTE’ (Cross Track Error),
the boat position relative to the track line, XTE resolution,
and XTE unit.
•
The lower screen section displays the magnitude of the XTE
in 1/1000 NM, or 1/100 NM if the message provides data
with only two decimal places.
Note !
The direction to steer is towards the track line. When the boat is
on track the boat icon will disappear while the track line
remains. The direction to the track line may not be the direction
to steer directly to the Waypoint, but may be important for safety
reasons; for instance, if the track passes close to shoals, or a
restricted area.
Screen 3
BEARING TO WAYPOINT
•
The upper screen section displays ‘BRNG TO WP’ and the
bearing type, ‘°M’ or ‘°T’.
•
The lower screen displays the bearing to the waypoint in
degrees.
Screen 3 has a sub-screen for setting the magnetic variation.
