Work prole setup | AP70/AP80 Operator Manual
When the vessel has a constant heading error due to external forces such as wind and current,
the Auto trim function corrects for this by building up a constant rudder offset.
The Auto trim value is reset every time the AUTO mode is entered or when a course change
greater than approximately 20° is made.
Auto trim is automatically disabled during a turn.
• Range: 10 - 800 sec
• Default: Depends on the vessel length
