3.7 Trails
In the true display, trails make it possible for you to reach a conclusion quickly about the manoeuvre
performed by targets. In the relative display, the trails provide a quick overview of the danger situation (a
constant bearing). However, only qualitative information can be obtained from them.
For radar echoes moving on the PPI, trails can be displayed. These trails can be varied as follows:
- The display of these trails can be switched on and off.
- Their length can be specified.
- If the screen stabilisation of the PPI is set to RM, the trails can be displayed with the PPI orientation
"North-Up" and "Course-Up" relative to own ship or with true (absolute) orientation, i.e. in relation
to the sea bottom

.
- The trails can be deleted so that they have to build up again.
Switching the Display of the Trails On and Off
The display of the trails is switched on and off by clicking on the
TRAILS area.
Specifying the Length of the Trails
Click on the TRAILS area by means of the MORE key; then, in the
menu that is opened as a result, either
a) click on the desired time, or
b) click into the (vertical) bar-area, drag the bar to the desired
value, and press the DO key, or
c) click into the upper numerical area and enter the value by
means of the virtual keyboard.
☞ If the trails are lengthened, they reach the new specified length
only after the time difference (i.e. in the case of switching over
from 12 to 30 minutes, 18 minutes will pass before the trails
correspond to a length of 30 minutes).
The reduction of the trail length too takes some time.
In the TRAILS area, the length currently being displayed is indi-
cated.
Switching the Trails to Relative or True Display
The switch-over is performed by clicking into the right-hand TRAILS
area.
☞ The switch-over is possible only in the RM modes "North-Up"
and "Course-Up". In TM mode, the trails displayed are always
true; in the RM mode "Head-Up", they are always relative.
Deletion of Trails
Click on the TRAILS area by means of the MORE key; then, in the
menu that is opened as a result, click (with the DO key) on RESET.
☞ The trails are also deleted whenever a switch-over occurs which
changes the entire radar video (RM/TM, PPI orientation, Range,
Center/OffCenter), but they then appear again.
