ADDITIONAL CRITERIA
Tick Add a point when the ship’s course changes more than ON and enter a value in
degree (an angle) in order to control more efficiently the track recording as and when the
course changes
In the example, ECDIS records one point every 15 seconds plus a point each time the ship’s
course changes by more than 5 degrees.
NOTE
Selecting a small time interval will generate a very big track file containing lots
of points that are time consuming to display. The above example avoids
making such a big file, without losing important ship track information.
ALARMS
Click on the Alarms tab to bring the Alarms page to the front.
The Check safety zone alarm is generated when the Checking ship alarm zone is crossing a
safety contour and/or dangerous chart objects. The alarm is always active when operating in
the Monitoring mode. See the
section for details.
The ECDIS regulations admit to disable the Collision avoidance alarm since it is the ARPA
system function. See the
section for details.
The XTD alarm (cross track distance) is always active when operating in the Operational
mode.
