7.10 Compass lock
Once you are satisfied with the compass accuracy, you can lock
the setting to prevent the autopilot system from completing a
further automatic linearization in the future.
This feature is particularly useful for vessels in environments that
are exposed to strong magnetic disturbances on a regular basis
(such as offshore wind farms or very busy rivers, for example).
In these situations it may be desirable to use the Compass lock
feature to disable the continuous linearization process, as the
magnetic interference may build a heading error over time.
Note: The compass lock may be released at any time, to
allow the compass continuous linearization to restart. This
is particularly useful if planning a long voyage. The earth’s
magnetic field will change significantly from one geographical
location to another, and the compass can continuously
compensate for the changes, ensuring you maintain accurate
heading data throughout the voyage.
