5.7.1 Trial Maneuvering in the True Vector Mode
In the True Vector mode, calculations are performed according to the values set
by Trial Speed, Trial Course and other features, and the result is displayed as a
bold-line that represents the change of own ship's vector as shown in the Fig 5-7
below (an example of the course changed to the right).
In this Fig 5-7, the dangerous target forward left becomes safe as a result of
simulation.
The tracked target information indicates the current CPA and TCPA values
regardless of the result of simulation.
