If the system has been configured to display raster charts the
available charts are displayed in a drop down list under the chart
engine, e.g.
SevenCs - ARCS . Each raster chart includes a brief
description of its coverage. For information on raster charts, see
`Using Raster Charts’ in Chapter 4 Charts.
Listed below each chart database are all the available charts within
an area of own ship, or if own ship isn't on the display, the charts
available at the centre of the screen.
