24.5.2 How to set conditions for viewing and logging of danger
targets
The operator may set Closest Point of Approach (CPA), Time to CPA (TCPA) and Log interval for viewing
dangerous tracked target and AIS targets on the ECDIS display. A dangerous tracked target or AIS target is blinking
and its color is green and red alternately. User can also alternatively log only information of a single selected tracked
target or AIS target.
1. Spin the scrollwheel to show Menu/Info/Chart Menu in the mouse functions area
then push the left mouse button.
2. Select Record from the menu and Settings from the submenu.
3. If the Danger Targets page is not already open, click the Danger Targets tab to open
it.

Set desired limits for CPA, TCPA and log interval. Note that these limits are only for ECDIS; a radar has its own
setting for dangerous targets and thus a target that is dangerous at an tracked target display can be safe on the
ECDIS and vice versa. If a tracked target is inside the CPA and TCPA, it is shown as a dangerous tracked target on
the ECDIS display. "Log interval" defines the time period for logging.
Note: The operator may select logging of the track of a single AIS and/or tracked target, if he selects in the Log
Single Target window the desired number from the tracked target and/or AIS box. If this option is selected, only
information of the target(s) selected is recorded.
24.5.3 How to save past track of a selected tracked target or AIS
target
To save past track of selected tracked target or AIS target, do the following:
1. Find number of tracked target or name of AIS target, by placing the cursor on the target and pushing the
scrollwheel.
2. Select Settings from the Record menu then open the Danger Targets page.
3. In the Log Single Target window, select tracked target number and/or AIS target name from the tracked target
and AIS boxes.
You can make a user chart from the danger target log. See section 24.10 " How to Make a User Chart from a Log
(past track)".
Note: By choosing a single target only the selected target's information is recorded. If you want to record
information of all danger targets, remove selection from the boxes in the Log Single Target window.
