•
AUTO ADJUST: When this option is selected the operator allows the system to adjust the heading to get
better behavior. The Auto Adjust option is used when the vessel is operating near or outside the sideways
capability. The system will auto adjust its heading Set Point into the current depending on the requested
sideways thrust needed. The maximum deviation can be set by the operator.
Note USE BOW THRUSTERS must be checked to activate these options.
•
USE BOW THRUSTERS: If checked the vessel will use the bow thrusters and thus is able to follow the track with
any heading (if weather and current conditions allow it).
If not checked the vessel runs the track using main propulsion and rudder only (The vessel's Heading will not be
according to track setting, it will be adjusted to run track).
•
CROSS TRACK:
•
ERROR: The shortest distance from vessel to track (perpendicular).
•
OFFSET: The distance that vessel should remain next to track.
•
ALARM: If the cross track error exceeds this value an alarm is activated.
•
TRACK ERROR: A trend that shows cross track errors over time.

•
ADD / DELETE / CLEAR: Add track segment, Delete track segment, Clear (Delete all) track segments (Figure 33:
Way Points on page 41).
•
RELATIVE / ABSOLUTE: Toggle track input between relative and absolute. Relative makes a track with bearing
and distance in meters, which will be relative to current position. The system will fix the track once it starts
tracking. When this button has been pressed the track will be absolute, meaning that the track is entered via
Latitude and Longitude.
•
Displays track segments relative (REL) or absolute (ABS) with Bearing, Distance, Latitude, Longitude, Speed,
Heading, Radius and rate of turn (ROT).
•
Each row displays a segment of the track, the current track section is indicated by the green arrow.
