SAFETY REGULATION

Attention!

For safety reasons, the preadjusted rudder limitation is also active

during R.o.T control.

If the preadjusted rudder limitation is too small, then the preadjusted

speed value will not be reached.

Note

The desired rate of turn depends

x on the initial turning behaviour of the ship

x and on the adjusted parameters.

When the ship starts turning, the rate of turn may be increased up to

approx. 50%!

Caution

Turning behaviour with preset rudder limitation:

If the adjusted rate of turn is not reached due to rudder limitation, the

rudder limitation is to be extended only step by step. ( steps of < 5 q ).

Otherwise, the rate of turn might considerably be exceeded because of

the integral component of the controller.

Note

Set course inputs differing by more than r 180 q from the

instantaneous heading of the ship are executed by NP2015/2025

through the shorter way as a matter of principle.

In case of a heading change of 180 q exactly, therefore, the direction of

heading change is uncertain!

Note

If the autopilot is connected via the steering mode selector or via an

external steering station, the main steering station is always switched

to the operating mode of Heading Control .

SAVETY REGULATION

Attention!

The values for R.o.T. or radius which are preset on the NP2015/2025

are overwritten by the external values (e.g. track planning system).

After switching back to e.g. Heading Control , check whether the

still--valid values for R.o.T. or radius provide for a safe heading-- or

track change!

Note

Operating mode of HEADING CONTROL

If the magnetic compass values and gyro compass values are

different, switching--over to the compass reference results in a

preset heading adaptation.

Possible course differences between set course and heading remain in

existence.

Operating mode of TRACK CONTROL

In this operation mode the actual heading may differ from the heading

indication, depending on the track error.

Note

Autopilot operation at high speeds.

(HSC High Speed Craft, according to IMO guidelines from 30kn to

70kn)

On pages HSC--1, HSC--2 and HSC--3 the behaviour rules for the

following situations are documented:

1. Sensor failures

2. Autopilot errors

3 Hazard when accelerating or changing course and in heavy

seas
