This function allows the potential collision point (PCP) or the closest point of
approach (CPA) for acquired targets to be indicated by a circular symbol at the
PPI.
approach (CPA) for acquired targets to be indicated by a circular symbol at the
PPI.
Acquired targets can be displayed with relative or true vectors.
TRUE allows the PCPs for all acquired targets to be displayed at the PPI.
RELATIVE allows the CPAs for all acquired targets to be displayed on the PPI.
Both types of display support prompt assessment of close range situations.

Potential collision points (PCP) provide a rapid overview of current and potential
collision danger.
Potential collision points (PCP) provide a rapid overview of current and potential
collision danger.
Assessment:
• There is a current collision danger if a PCP lies on your own
ship’s head up line.
• There is a potential collision danger if your own ship changes
its current course such that a PCP that did not previously lie on the
ship’s head up line will now lie on that line.
ship’s head up line will now lie on that line.
Potential collision points are calculated after target acquisition.
Every target is normally marked with one PCP, which appears as a small circle.
Under certain circumstances, it is possible that a target is marked by 2 PCPs.
In such a situation, both PCPs are applicable and must be taken into account
when viewing the Radar image.
