5.7.3 Operation of Trial Maneuvering Function
Procedures
1) Open the Trial Maneuver menu by performing the following menu
operation.
→
2) Left-click the item button of .
The Trial Function will be set to on or off.
When the Trial Function is active, the character " T " will display at the bottom of the radar
display.
3) Set values for Course by turning the [EBL] dial, and for Speed by
turning the [VRM] dial.
4) Set other characteristics.
For inputs to the value input screen, refer to Section 3.3.4.2 "Directly entering a numeric
value".
Dangerous target symbols are displayed in red and safe target symbols in white.
: The trial maneuvering function is turned on.
: The trial maneuvering function is turned off.
: Vector time (1 to 60 min)
: Time until trial maneuvering is started (0 to 30 min)
: Dynamic trait of the own ship
→
: Range from when steered to when the ship
beings to turn (0 to 2000 m)
→
: Turning radius (0.10 to 2.00 nm)
→
: Acceleration (0.0 to 100 knots/min)
→
: Deceleration (0.0 to 100 knots/min)

Vector Time is valid only when Trial Function is set to on. If it is off, the vector time
before trial maneuvering is displayed.
Time until the start of trial maneuvering is counted down immediately after the input.
The acceleration and deceleration are influenced depending on the relationship
between the current speed and the input speed for trial maneuvering.
If 0.0 kn/min is set for Acceleration when the speed for trial maneuvering is faster
than the current speed, or for Deceleration when the speed for trial maneuvering is
slower than the current speed, the system performs simulation on the assumption
that the speed is changed immediately after the time set for Time to Maneuver .
