Plotting Aids (ARPA) function *1 *2

The simplified ARPA function assists you to prevent
your vessel from colliding with other vessels orobjects. When a target enters the preset watch
area, it is automatically tracked on the radarecho. By selecting one of the targets, the target
information, such as position, course, speed, CPA(Closest Point of Approach), TCPA (Time to CPA),
bearing, and distance is displayed. When a target
enters the CPA, or it exceeds the set TCPA, analarm sounds to warn you.

By selecting an AIS icon, vessel information such as
AIS class, MMSI number, vessel name, course,speed, CPA, TCPA,
bearing, anddistance isdisplayed.
