12. Select the speed setting box. Use the scrollwheel to set the speed.
Note: Course and speed may also be set with the EBL and VRM,
respectively. Put the cursor in any one of the four trial maneuver
related boxes and operate applicable control.
13. Select TRIAL SET. Push the left button or the scrollwheel. The TRIAL box
shows "TRAIL 00:00" (00:00 is trial maneuver time).
The time indication depends on trial mode:
Dynamic mode: The position of your ship and tracked targets is updated and
displayed every 30 seconds.
Static mode: The position of your ship and tracked targets when set course and
speed are reached are displayed. The progress time until the position is reached
is indicated on the display. The trial time can be changed from the Trial Time box.
Put the cursor in the Trial Time box and roll the scrollwheel. The position of
targets at the end of selected time is shown. Increase or decrease the time to
get a safe manuever. When the cursor is removed from the box the original
positions of your ship and tracked targets are restored. If a manuever is unsafe,
change speed, course and delay until it is safe.
The trial maneuver takes place with the letter "T" displayed at the bottom of the
screen. The time appears at the top right side of the display. If any tracked target
is predicted to be on a collision course with own ship (that is, the target ship
comes within preset CPA/TCPA limits), the target plotting symbol is red. If this
happens, change own ship's trial speed, course or delay time to obtain a safe
maneuver.
3.16.3 Terminating a trial maneuver
A trial maneuver is automatically terminated at the end of the fixed time and the
normal radar display is restored. The time of termination depends on the trial
mode as follows:
Dynamic mode: The trial is terminated when 60 minutes is shown in the Trial
Time Box.
Static mode: The trial is terminated when there is no key operation within one
minute.
To terminate the trial maneuver manually, put the cursor in the Trial Time box
then push the left button to show TRAIL OFF in the box.
Note: To stop the trial maneuver, select OFF at step 5 in the procedure in
section 3.16.2.
