Trial Maneuvering in the Relative Vector Mode･･･････････････
The result of trial maneuvering in the Relative Vector mode is shown by a change in target
vector. In the figure below (with the same conditions as in the True Vector mode on the
previous page), it is seen that the acquired target is a dangerous one because its vector is
crossing the CPA RING.
The above figure shows that the relative vector of the target has changed as shown in the
figure as a result of simulation (course and speed), so that the target’s symbol is changed to
“○”; i.e., a safe target. As was the case in the True Vector mode, the data display field
indicates the current values of CPA LIMIT and TCPA LIMIT, not those as the result of the
simulation.
The course change of own ship is displayed as a dotted line.
