1.3 The Chartplotter Display
The 
hsb
2
 (PLUS) series LCD Display can include a Chartplotter. The 
chartplotter includes a small-scale world map and detailed navigation 
information is displayed when a cartographic chart card is installed. The 
details displayed depend on the chart zoom level selected. A plotter mode is 
provided to enable route plotting and tracking at large scales even when a chart 
card is not installed, or when the chart is zoomed beyond the available 
cartographic detail. A typical chartplotter screen is shown in Figure 1-3.
The chartplotter uses position information from a GPS, DGPS, WAAS or 
Loran-C instrument. Once the 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.
The chartplotter screen includes a status bar that displays chart scale, with 
either cursor position, range and bearing or, when the cursor is homed to the 
vessel (by pressing FIND SHIP), vessel position, Speed Over Ground (SOG), 
Course Over Ground (COG) and fix type (VES POS, DIF FIX or SD FIX). 
The status bar also indicates if radar/chart overlay is switched on.
Any waypoints you have placed are displayed (unless you turned them off in 
Chart Set Up as described in Chapter 7) and the current route is shown. 
Information can be viewed on-screen by positioning the cursor over a 
waypoint, current route or chart object. The chartplotter screen can also show 
additional information, depending on your currently selected options, set up 
selections and data available from other equipment. 
An example chart display, in its default configuration, with a chart card 
installed, is shown in the following illustration.
Several functions are available to control the display as follows:
Zoom in/out and Pan the Display
Offset the Chart or Center the Chart around the Vessel
Overlay Radar Targets onto the Chart Display
Synchronize the Chart and Radar (if radar data is available)
Operation of these functions is described in Chapter 2.
