6.10 Verifying Datum
Datum is used to choose between different models of the earth. It is essential that you use datum in a consistent way.
If you use paper charts together with electronic chart material, it is recommended that you use the same datum as
your current paper chart to avoid misalignment between your electronic chart system and points taken or plotted on
your current paper chart.
Once you have chosen a datum, all
numerical latitude-longitude
position values are presented in
your chosen datum.
To change the datum:
1. Choose the datum indication in
the top box in the information
area.
2. Spin the thumbwheel to choose
appropriate datum, the one that
matches your paper charts, and
then push the thumbwheel.
Note: ARCS raster charts contain some rasterized position information, like scale bars on PA paper charts, which is
true only if you have chosen native datum of that ARCS chart.
