4.14 AIS Collision Alarm (CPA, TCPA)
This radar calculates CPA and TCPA by using own ship and relative target positions.
An AIS dangerous target is one whose CPA and TCPA are within the range of the CPA
and TCPA limits set in the TT/AIS box. The AIS symbol of an AIS dangerous target is
red and flashing, and is announced with the Alert "CPA/TCPA". After the alert is ac-
knowledged the target symbol is displayed in red color.
Note: Only AIS targets (class A and B AIS targets and SAR vessels) are subject to the
CPA/TCPA alarm.

propriate indication in the [TT] box.
