There are two
PLOT
screens available in the basic MX420 navigator
models. The
RTE1
and
WPT
functions are highly interactive with the
PLOT
screens. The primary difference between the
PLOT1
and
PLOT2
screens is the point of reference. The
PLOT1
screen displays graphic
information around the boat at your present position. The boat always
remains in the center of the screen. The
PLOT2
screen displays graphic
information around a marker. The marker always remains in the center
of this screen. If you define some of your navigation markers in the
Waypoint Bank with a symbol in the first character position, the navi-
gation symbol will show up in relation to your planned course on the
plot screen, just as it does in the
NAV1
Panorama
screen. In addition
to the graphic details provided by the CDU, the
Plot
screens provide
basic navigation information, zoom-in/out capability and scaling fac-
tors for the display from around 10 to 20 meters, depending on your
latitude, out to 128 nautical miles. You will find these screens very
helpful in many ways, and we will provide you with a couple of ideas
on how to make good use of the
PLOT
function after the screen de-
scription which follows.
For MX420/AIS models, a third plot screen
PLOT3
is available which
shows the locations of other AIS equipped vessels relative to your
ships position. Additional softkeys can be brought up by pressing
the E key. More detailed information about the PLOT3 screen is avail-
able in Appendix-A page 154 of this manual.
Note: The Plot screens do not show your route and cross-track
error lines when in Great Circle Navigation mode.

CFG

PLOT
functions:
