Targets
You can setup
a CPA/TCPA and/or a Proximity alarm under the Alarm Option Menu.
The CPA/TCPA alarm can be used to detect possible threat even if the targets are far away. The
CPA/TCPA alarm uses the speed and course of both the target and your own ship to make the
calculation.
The proximity alarm is only used in close range situation. Usually, it is used as a "tier 2" alarm to raise
attention about immediate threat.
Note that even if the CPA/TCPA or Proximity alarm are unchecked from the Alarm menu, the
dangerous target icons (red) will be used when the targets are breaking the alarm conditions.
For example how the alarm will be activate with an AIS Target depending on the vessel position :
In this case the AIS position alarm is displayed in the title bar, the distance between the Own ship and
the AIS vessel target is shorter than the CPA alarm value defined in the Alarm options menu. The AIS
target will be colored in red when the Dangerous CPA value is reached (this value can be fixed under
the Targets options menu)
