A-Series display - User reference manual
Your position
Your current position is represented by a boat symbol. Your
position is also displayed in the data bar under VES POS.
A solid circle on the chart indicates that neither heading nor
Course Over Ground (COG) data is available.
If your position is outside the area of chart currently shown in the
chart window, the vessel symbol will not be visible. You can tell the
system to locate your vessel and centre the chart display about it.
To locate your vessel
1. Press the
FIND
softkey to switch between the
SHIP
and Cursor
location.
Moving around the chart
To move around the chart and display the area required at an appro-
priate scale, use the track pad and range in/out buttons.
Note:
Remember that the cartographic detail available on the chart
will vary according to the chart and chart scale. Some charts
provide details at smaller scales than others.
Autoscale
A feature of the chart application is ‘autoscale’. If you select a chart
scale that does not have cartographic detail in some areas, the
chart will automatically use the most detailed level available for the
surrounding area and stretch it to fit the selected scale. This means
that you will never have blank or hatched areas on the screen. How-
ever, there may be some misalignment of objects which cross the
chart boundary in this area.
