Depending on the used display range a suitable vector length should be set so that the results of the
trial manoeuvre are clearly visible.
Fig. A / 16 Vector Display in Trial Manoeuvre Mode
The general screen-stabilisation and the alignment of the heading line may remain unchanged, or
can be set by the operator as required. With other words, the Trial Manoeuvre can be observed in
True or Relative Motion and in Head Up, North Up or Course up orientation.
Simulating a Course Manoeuvre
Use the Course and Radius slider to set the desired amount of
course change and the radius with which the manoeuvre is to be
simulated.
During adjustment, the simulated course change is displayed in
form of a curved headline. A change of max. +/- 180° relative
to your present course can be simulated. The heading and the
present course is updated automatically if your ship is turning
during the manoeuvre simulation.
After course and radius have been set, use the Time slider to simu-
late your ship sailing along the pre-planned course change. All displayed targets will move accordingly
with their current speed and course and the change of their relative vectors will show the further devel-
opment of the scenario step by step.
The time setting can be done continuously by moving the slider or (by clicking) stepwise in 10 sec incre-
ments up to 30 min complete duration.
Because of the REL Vector Mode, the relative speed vectors are rotated and change their length by
the simulated course-change. If one of the targets will change its status from dangerous to not
dangerous and vice versa, this will be shown by a change of their symbol's colour.
