Chart Alert With ARCS Charts

In case of ARCS charts, the operator can define danger areas by using a user chart. The system can use user chart
symbols, lines and areas and calculate chart alert from this material. For further details, see Chapter 15 "User Chart
Control".
This figure shows a chart alert used with an ARCS chart. The chart alert calculation is done with route and predicted
movement of your ship.
To get a chart alert with a user chart, when you start planning a future voyage, do the following:
1. Create a new user chart or select an existing one where lines and/or areas for chart alerts have been defined. See
Chapter 15 for how to create a user chart.
2. Check that "Chart Alert Warning Area" is set for display. See section 11.2.3 "How to highlight chart alerts" for
the procedure.
3. Select user chart danger area indication or alert position. See section 11.2.2 "Choosing objects used in chart
alerts" for the procedure.
4. In the route planning mode, define a new route or select an existing one. Make a chart alert for the route if there
are indications of danger areas along the route. Modify your route if necessary. See section 11.5 "Route
Planning".
5. Select the route as monitored route, by using Exchange with Monitor in the Route menu.
6. Set watch sector for your ship. See section 11.4 "How to Activate Own Ship Check" for the procedure.
The system is ready for chart alerts based on user chart for monitored route, planned route and your ship.
