There are four basic
NAV
screens.
NAV4
only provides data if appro-
priate sensors (e.g. wind speed/direction logs, NMEA compass, etc.)
are interfaced and activated on the CDU. The
NAV
functions are highly
interactive with the
RTE1
screen, and a number of
CFG
menu selec-
tions.
The
RTE1
screen provides the active route for the
NAV
screens. It
also maintains a waypoint pass log for you. One other important fea-
ture in the
RTE1
screen that you need to be aware of is that the
up
and
down
arrow softkeys control which waypoints are skipped (down ar-
row) and which are restored (up arrow) for your current route. The ETA
information is configured in the RTE 1 screen. Refer to the
Route
sec-
tion of the manual for a full description.
The following
CFG
menus directly impact the
NAV
functions:
¾
COG SOG - sets the filtering time for the displayed values.
¾
Datum - sets the reference datum for your present position and
waypoints in the active route.
¾
GPS Offset - sets an offset for calculating the GPS antenna posi-
tion if you can’t physically locate the antenna exactly where you
want it (e.g. over the centerline of the boat).
