Those modes containing more than one page of data provide additional
soft keys giving access to the sub-sets of data within each group, each
cycled through with the associated soft key.
1.3 The Chartplotter Display
The chartplotter includes a small-scale world map. Detailed navigation
information is displayed when a C-MAP NT
®
chart card is installed. A
plotter mode is provided to enable route plotting and tracking at large
scales even when a chart card is not installed.
Note: The default world map scale is 1200nm.
When a position fix has been established, your vessel’s position, if on
screen, is shown as a boat shape, pointing in the direction of the current
heading (or COG if heading data is not available). If no heading or COG
data is available, the vessel is shown as a circle.
A status bar at the top of the screen displays the scale, with either cursor
position, range and bearing or, when the cursor is homed (locked) to the
vessel (by pressing
FIND SHIP), vessel position, Speed Over Ground
(SOG) and Course Over Ground (COG).
Note: When the cursor is homed, it is ‘locked’ to the vessel and moves
with it. The screen is automatically panned to keep the vessel and cursor
in such a position that they are 10% from the edge of the window with the
heading vector (be it shown or not) passing through the center of the win-
dow.
The current route is shown and any waypoints you have placed are
displayed (unless you set them to off in Set Up). Information can be
viewed on-screen by positioning the cursor over a waypoint, current
route, track or chart object.
Functions are available to control the display as follows:
• Zoom in/out
• Pan the Display
• Centre the Chart on the Vessel
