Track Change Maneuver
(see Figure 16)
On planning the routes, attention is to be paid to the fact that from the end of the
radius of a track change maneuver to the beginning of the radius of the next track
change maneuver at least 350 m are to be planned. This distance is required to
bring the ship to the necessary rate of turn. The minimum distance between both
radii depends on the
vessel’s maneuverability.
If this is not the case, the result may be that the planned radii cannot be realized.
This will be signalized on the operator unit by the error message Track Ctrl. Interr.
(Track Control Interrupted) and a continuous audible alarm (see section
1.4.5.1.7.4).
Figure 16: Procedure of the Track Change maneuver (Example)
The following alert will be displayed on the ECDIS only for NP5100, NP5300 and
NP5400 (also refer to ECDIS manual). For the NP5500 the alert will be displayed on
the ECDIS as well as on the Autopilot.
Attention!
The track change maneuvers are planned and checked on the ECDIS. No check
within the Autopilot takes place. A limitation, however, is incorporated.
If a non- realizable small radius is transmitted to the Autopilot, this may lead
to hard- over rudder positions!
