Switching On the Trial Manoeuvre Dialog in REL Vector Mode
- Switch to REL in the Vector &Trails group on the permanent
area.
- In the Targets group choose On for the Trial control.
In the Non-permanent area, the Trial Manoeuvre dialog window
appears, with the following data:
- Course: The currently existing course (the course is changed
when the ship is turning)
1)
- Speed: The currently existing speed (the value is constant
and taken as start speed)
1)
- Radius: The radius with which the manoeuvre is to be simu-
lated. If the dialog has not been used before, the minimum
radius is displayed, otherwise it shows the last used radius.
- Delay: 0 minutes. Can be set for simulation of a delayed start of the manoeuvre.
- Time: 0 minutes. Must be set for simulation of the time instances during the manoeuvre.
The following changes occur in the PPI or chart area after activation of the trial manoeuvre function
2)
:
- In the lower region of the application area a large symbol is shown to draw the operator's atten-
tion to the fact that the trial manoeuvre display is switched on and that after starting the simulation
by changing the time slider, consequently the symbols and vectors of the targets are no longer
displayed in accordance with the real situation that actually exists at that time.
- The vector display (of the targets) must be switched on during observation of the manoeuvre.
- The vectors and the video trails (if any exist), are displayed relative and
- the own ship is shown without vector but always with the correct present heading line.
- Past position plots are not displayed during the trial manoeuvre, but (if Plot is in the switched on
state) they are continuously built up in the back-ground and are visible again as soon as the trial
manoeuvre is ended.
Because the currently existing values were taken over, no manoeuvre has been simulated yet. As
long as the Time bar remains at zero position the display content is still corresponding to the real
situation.
Setting the Trial Manoeuvre in REL Vector Mode
In case the vector display during the trial manoeuvre is a relative display, a collision course can be recog-
nised from the fact that the vector of a target is pointing towards the own ship symbol (constant
bearing). A manoeuvre of your own ship must be simulated which avoids this constant bearing while at
the same time fulfilling other conditions (e.g. keeping within the channel, avoiding shallow water and
obstructions, avoiding other ships, etc.).

The resultant value used for the display of the own ship speed vector during simulation
2)
The radar video and the true or relative target trails are updated as normal and are not influenced by the
manoeuvre simulation.
