Select between Midship or Actual rudder position in Work

mode.

When “Midship” is selected, the autopilot will use zero degrees

as the midship reference. Hence, the rudder will always move

to midship when switching from STANDBY or DODGE mode

to AUTO-WORK or NAV-WORK mode.

When “Actual” is selected, the autopilot will use the current

rudder position as the midship reference (bumpless transfer)

when switching from STANDBY or DODGE mode to AUTO-

WORK, or NAV-WORK.

Note ! “Midship” will always be used when switching to AUTO or

NAV from STBY/NFU/FU.

W Autotrim

Rotate the course knob to turn the Autotrim function off or on

in the AUTO-WORK and NAV-WORK modes.

Autotrim

When the vessel has a constant heading error due to external

forces such as wind and current, the Autotrim function corrects

for this by building up a constant rudder offset.

The value for the Autotrim parameter is the time it is allowed to

calculate the rudder offset.
