HEADING CONTROL operating
mode.
Set during
Initial putting into operation,
test run
Every ship has its own time constant, depending on its mass
and load. This constant must be observed during a heading
change maneouvre.
Before reaching the new set heading, the R.o.T. must be mini-
mised on time (e.g. by counter rudder).
This effect is set by the counter rudder (CNT.RUD).
Tendency -- counter rudder too great:
Ship overshoot avoided before reaching the new set
heading.
Tendency -- counter rudder too low:
The ship is not stopped on time and overshoots the preset
heading.
2.3.1
10 SPEED When there is no log sensor on
board, the current speed must be
set manually.
The ship’s behaviour depends on its speed.
To ensure optimal control, the controller must be adjusted for
the speed.
2.3
11 TRACK< > TRACK operating mode.
Setting
--track deviation is too great
(drift)
--too much gain in track
controller.
Tendency -- not enough gain in track controller:
Drift influences are strong and result in a greater track
deviation.
Accuracy can be increased by the amplification setting
(greater) TRACK > .
Tendency -- too much gain in track controller:
Reduce the amplification setting via TRACK< until the
required setting is reached.
Optimum between accuracy and controller gain
(heading trim).
2.3.5

:
SYCHRON. No absolute heading transmis-
sion from the heading sensor
(gyro compass) to the PILOT-
STAR D is used.
Set
--during initial putting into
operation
--desynchronization after power
failure
The heading display between the compass and the
PILOTSTAR D is desynchronized.
2.3.6
13 XTE TRIM TRACK operating mode.
Set when
The track controller is not yet
functioning optimally.
The temporal coordination of the track error compensation has
not been correctly adjusted.
Track error correction is too slow or too fast
(see figure in Chap. 2.4.1).
2.4.1

:
SPECI SL HEADING CONTROL operating
mode.
(test run).
Set during
Initial Putting into Operation.
Heading behaviour is still not
optimal after a change in
heading.
A stepwise increase in previous
measure CNT.RUD and a
stepwise decrease in
RUDDER is unsuccessful.
In most cases, an approximate entry of the ship’s length
(S_LENGTH) fulfils the requirements of the PILOTSTAR D for
an optimal heading control.
SPECI SL is available for special cases.
With this feature, the ship’s length can be increased or decrea-
sed as a percentage, whereby the temporal control behaviour
is influenced.
The resulting ship’s length must not necessarily correspond to
the original length .
