Operation of Trial Maneuvering Function
Procedures 1 Press the [TT MENU] key.
2 Open the Trial Maneuver menu by performing the following menu
operation.
3. Trial Maneuver
3 Press the [1] key.
The Trial Function will be set to on or off.
On : The trial maneuvering function is turned on.
Off : The trial maneuvering function is turned off.
When the Trial Function is active, the character " T " will display at the bottom of the
radar display.
4 Set values for Course by turning the [EBL] dial, and for Speed by
turning the [VRM] dial.
5 Set other characteristics.
Vector Time : Vector time (1 to 60 min)
Time to Maneuver : Time until trial maneuvering is started (0 to 30 min)
Own Ship Dynamic Trait> : Dynamic trait of the own ship
→ Reach : Range from when steered to when the ship
beings to turn (0 to 2000 m)
→ Turn Radius : Turning radius (0.10 to 2.00 NM)
→ Acceleration : Acceleration (0.0 to 100 kn/min)
→ Deceleration : Deceleration (0.0 to 100 kn/min)
For inputs to the value input screen, refer to Section 3.3.4.
Dangerous target symbols are displayed in red and safe target symbols in white.
* 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 .
Cancellation 1 Press the [1] key while the Trial Maneuver menu is displayed.
The Trial Function will be set to on or off.
Off : The trial maneuvering function is turned off.
