Plot
There are two PLOT screens available in the basic MX500 naviga-
tor 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 posi-
tion. 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 navigation symbol will show up in rela-
tion 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 factors 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 description which follows.
Note: The Plot screens do not show your route and cross-
track error lines when in Great Circle Navigation mode.
