Rudder source selection, AP44
Ú
Note: Virtual Rudder Feedback (VRF) should only be used if no
rudder feedback is available. Installing a feedback unit will
enhance the performance of an autopilot and provide an
accurate rudder angle indicator on the autopilot display.
Ú
Note: VRF is not available if boat type is set to Sail.
Rudder feedback calibration
Ú
Note: Only available if you have a rudder feedback unit installed
and selected as rudder source.
The rudder feedback calibration determines the rudder feedback's
direction.
• Follow the on-screen guided steps until the rudder calibration is
completed.
Rudder test
This rudder test verifies the drive direction. It detects minimum
power to drive the rudder and reduces the rudder speed if it
exceeds the maximum preferred speed for autopilot operation.
Ú
Note: If the boat uses power assisted steering, it is important
that the engine or electric motor used to enable the power
assist steering is turned on prior to this test.
• Run the rudder test as described in the on-screen instructions
- Rudder should make a small movement within 10 seconds,
then follow up with travelling both directions
