TP Deactivated
The TRACKPILOT has been deactivated and is no longer controlling the rudder. The ship must be
steered manually or by another autopilot.
NOTE: This alarm is optional and must be configured on service level if required by the class or the
owner.
TP Drift Angle Limit
The pre-set drift limit value for the Trackpilot has been exceeded; for correct course or track-
keeping, a larger compensation angle is needed.
Even after acknowledgement, the drift angle contained in the actual course is limited for the TRACK-
PILOT to the drift limit setting.
Remedy: Increase the drift limit value or switch over to Heading mode or to manual steering.
TP End of Track
The ship, sailing in Track mode, will pass the last waypoint of the System Route in 60 seconds.
Special features: Acknowledgement causes a switch-over to Course mode; the ship’s course has
to be set manually from now on.
If the alarm is not acknowledged within 30 seconds, the Trackpilot Alarm signal is generated for
the purposes of triggering an external alarm. See 2.2.6 on page V-32.
TP GC Course Change
Track mode is switched on and the sailing mode is set to Great Circle. In order to remain on the
Great Circle, a course change is necessary which exceeds 3 degrees or half of the set Course Limit.
The new course is displayed as Next course in the TRACKPILOT data display.
Special features: Acknowledge with Execute. Regardless of whether this alarm is acknowledged
or not, the planned change of the course takes place at the WOP.
TP Heading Change Due to Drift
The ship is sailing in Course mode or Track mode and a drift change of more than 5° has occurred
as a result of switch-over (manual or automatic) of the selected SOG speed sensor.
Special feature: Up until acknowledgement takes place, the TRACKPILOT uses the longitudinal and
transverse speeds that were valid before the alarm. After acknowledgement, the TRACKPILOT uses
the new longitudinal and transverse speeds, so that a heading change which is of the same order
of magnitude as the drift difference occurs automatically.
Remedy: Select Heading mode to avoid any heading change caused by a switch over of the speed
sensor.
TP Heading Sensor Fault
The TRACKPILOT is in the activated state and the compass system or its transmission unit has
been switched off, is reporting incorrect data, or has failed.
- or -
With the TRACKPILOT in the activated state, the gyro heading value
- has jumped by more than 1 degree betwen two high speed transmissions.
