Chart Alerts - Furuno FCR-2107 Operator's Manual

9. Chart Alerts

The chart radar can detect areas where the depth is less than the safety contour or detect an area where a specified
condition exists. If you plan a route or if prediction of own ship movement goes across a safety contour or an area
where a specified condition exists, the system will display a visual alert or sound an audible alert to alert you to
impending danger. For this function, the chart radar utilises the chart database (S57 charts) stored on the hard disk in
SENC format. Note that the chart radar calculates dangerous areas using the largest scale chart available, that
may not be the visualised chart.
You can choose objects that are included for calculation of danger area (for example, restricted areas). A window
lists the various areas that activate danger warnings.
You can also define your own safe area by creating a user chart area. The system can utilise these areas when
calculating chart alerts.
The chart radar can check the following for you:
•
Predicted movement area of own ship
•
Planned route with an easy to use locator function to find dangerous areas
The chart radar will highlight the following for you:
•
Dangerous areas inside predicted movement area of the own ship
•
Dangerous areas inside your monitored route
•
Dangerous areas inside your planned route
