6-55 Section 6 Target Tracking and AIS
6.13.2 Performing a trial manoeuvre
[Operation procedure]
Open the Trial (Trial Manoeuver) screen by performing the following menu operations.
[Menu] button → TT/AIS → Trial Manoeuver
1 Select the [Trial Function] checkbox.
The trial function is turned on.
When Trial Function is set to On, the character "T" blinks at the bottom of the own ship display
field in the radar display and means a trial manoeuvre.
2 Click on the [Course] and [Speed] boxes and enter setting values.
[Course] can be set up by turning the [EBL] dial and [Speed] by turning the [VRM] dial.
3 Set other characteristics.
[Vector Time]: Vector time (1 to 120 min)
[Time to Manoeuver]: Time until trial manoeuvring is started (0 to 30 min)
[Own Ship's Dynamic Trait]:
A dialogue for setting a dynamic trait of own ship is displayed.
For the setting of [Own Ship’s Dynamic Trait], refer to “13.9 Setting Own Ship’s Dynamic Trait”.
The dangerous target symbol is displayed in red and the safe target symbol is displayed in
white.
The safe target symbol colour can be changed by using [Target Symbol] that is displayed by
selecting [Settings] - [Colour and Brightness]. For the details, refer to "13.22 Setting Colours
and Brightness".
Vector Time is valid only when Trial Function is set to On. If it is Off, the vector time before trial
manoeuvring is displayed.
Time until the start of trial manoeuvring is counted down directly after the input.
The acceleration and deceleration are influenced depending on the relationship between the current
speed and the input speed for trial manoeuvring.
If 0.0 kn/min is set for [Acceleration] when the speed for trial manoeuvring is faster than the current
speed, or for [Deceleration] when the speed for trial manoeuvring is slower than the current speed, the
system performs simulation on the assumption that the speed is changed directly after the time set for
[Time to Manoeuvre].
To finish trial operation:
1 Clear the [Trial Function] checkbox.
