Reference section 4 — Navigating to Waypoints
Steering to a waypoint
Reference Manual Revision B
Steer Screens
There are two versions of the steer screen.
The
2D Steer
screen is a simple graphic
display of cross-track distance. The
3D Steer
screen is similar, but from an “overhead”
perspective view that also shows nearby
waypoints.
Press
STEER
to switch between the screens.
The 2D steering screen
The
2D Steer
screen uses a traditional
two-dimensional display that shows your
cross-track distance — how far your vessel
is from your intended track line (the center
line of the display). The vessel symbol on
the display rotates as your vessel turns,
showing whether you are moving closer to
the line or further from the line.
Ideally, you’ll keep the vessel symbol close
to the track line and parallel to it.
The scale of the cross-track display is
shown near the bottom of the screen. To
change the cross-track scale, press the
zoom
IN
or
OUT
keys.
If the cross-track alarm is turned on, the
alarm limits are displayed as red lines
within the cross-track display.
Note that the heading correction display on
the 2D screen (showing “Come 30° Right,”
below) indicates the heading change
needed to sail parallel to the desired track
line. This is the correction to make
after
you
are on the line.
The direction in which your vessel symbol
is pointing tells you the direction you’re
actually travelling (your COG). This direc-
tion may not be the same as your heading,
if any current or wind is present.
When the 972 sequences to a new leg of a
route, your vessel symbol will immediately
show your COG relative to the new leg.
