Control Parameters
NautoPilot® 5100, NP 5300 and NP 5400:
The ECDIS transmits Course Over Ground (COG), Rate of Turn (RoT) and Cross
Track Error (XTE) to the Autopilot. The ECDIS transmits no waypoints and the
Autopilot re- quests no data for a track.
NautoPilot® 5500 only:
Before Track Control is started, WPTs are transmitted to the Autopilot (up to 4 way-
points). This process is called initialization.
During this initialization all necessary data for Track Control are transmitted to
the Autopilot.
Further WPTs (and data) are transmitted during Track Control from the ECDIS to the
Autopilot on request of the Autopilot.
After initialization, the Autopilot is switched into Track Control mode and the ship
approaches the first track section.
Within a time between 3 to 5 min before a track change maneuver starts, the
operator is notified of the forthcoming track change maneuver by means of a
message from the Autopilot. The time can be selected at the ECDIS. This message
must be acknowledged by the operator. 30 seconds before the track change
maneuver starts, the operator is requested by the Autopilot to acknowledge the
forthcoming track change. The track change is realized even if those messages are
not acknowledged.
At the end of the route, the operator is notified by an alarm that the ship is at track
end, and he is requested to change over to Heading Control mode or manual
mode.
The activation of Track Control is only possible under the following conditions:
10000001052
