4.14 Using the radar with the chart
You can enhance the use of your chart by combining it with the following radar
features:
• Radar range synchronization
•MARPA.
•Radar overlay.
Synchronizing the chart with radar range
When synchronization is switched on:
• The radar range in all radar windows, changes to match the chart scale.
• ‘Sync’ is indicated in the top left-hand corner of the chart window.
• If you change the radar range, in any radar window, all synchronized chart views
change scale to match.
• If you change the scale of a synchronized chart window, all radar windows change
range to match.
To set the radar range synchronization:
Notes: (1)
Radar range synchronization is not available when the chart motion
mode is set to Autorange.
(2)
The 2D chart can be synchronized with either the 3D chart (see page 113)
or the radar but not both.
Viewing MARPA targets on the chart
The Mini Automatic Radar Plotting Aid (MARPA) function is used for target tracking
and risk analysis. Although set up in radar mode or radar overlay, all MARPA targets
are displayed in the chart window and associated MARPA functions can be accessed
via the chart. For detailed information on MARPA see
page 165
