Section 6 Target Tracking and AIS 6-72
Trial maneuvering in the true vector mode
If the own ship's vector mode is the true vector mode, the own ship's vector is calculated according to
the own ship's trial speed and trial course as well as the own ship's dynamic characteristic, and the
result is displayed as the own ship's expected course. The following figures show an example of
veering to the left: the dangerous target at front right has changed to a safe target as a result of trial
maneuver.
The tracked target information indicates the current CPA and TCPA values regardless of the result of
simulation.
