Static trial maneuver
A static trial maneuver displays only the final situation of the simulation. If you enter the same
trial speed, course and delay time under the same situation as in the aforementioned example
of dynamic trial maneuver, the screen will instantly show position OS7 for own ship, position
A7 for target A and position B7 for target B, omitting the intermediate positions. Thus, the
static trial maneuver will be convenient when you wish to know the maneuver result
immediately.
Note: For accurate simulation of ship movements in a trial maneuver, own ship's
characteristics such as acceleration and turning performance should be properly set in initial
settings at the time of installation.
