2.41.4 Chart database information
You can select the quantity of objects and text to display on the chart radar screen,
with the [Chart database] button on the Status bar. There are four different pre-defined
settings available and one user-definable ([PERSONAL]). Indication of selected set-
ting appears on the label of the [Chart database] button. The [Chart ON/OFF] button
(on the InstantAccess bar) must be ON to show the [Chart database] button. The
[Chart database] button is grayed out if the [Chart ON/OFF] button is OFF.
2.41.5 Chart scale indications
The system alerts you to the availability of larger
scale ENC and overscale, at the top-left posi-
tion.
When the radar display range is higher than the
chart scale of the ENC chart, the indication,
"Larger scale ENC" is displayed. For example,
the radar range is 24 NM and the range avail-
able with the ENC chart is less than 12 NM.
When the radar display range is lower than the
chart scale of the ENC chart, the indication
"Overscale x.xx" (x.xx=overscale factor). For ex-
ample, the radar range is 0.25 NM and the chart scale is 0.5 NM.
If both conditions exist, both indications are displayed.
2.41.6 Chart status
The indication "Chart Status" appears at the top-right position on the screen when the
