Chapter 2: Commissioning Procedures 37
AutoLearn
AutoLearn enables the autopilot to ‘learn’ the vessel’s steering characteristics, by
carrying out a number of maneuvers.
Requirement for a clear area
The Autolearn setup feature performs a series of 7
or 8 turns at normal cruising speed. The amount of
clear water required depends upon the cruising
speed of your vessel, but minimum requirements
are.
•
A typical non-planing vessel at traveling at
6 kts requires a minimum area of clear water
100 m wide and 500 m ahead.
• A typical planing vessel at traveling at 20 kts
requires a minimum area of clear water 500 m wide and 2000 m ahead.
Procedure
1. When the AutoLearn entry page is displayed
press
OK
to continue to the AutoLearn warning
page.
2. Ensure there is sufficient free water in front of
the vessel to enable the AutoLearn to be safely
completed.
3. Ensure it is safe to proceed, then press
AUTO
to start the AutoLearn. During AutoLearn:
•
Maintain a normal cruising speed (at least 3
knots).
• A number of instructions will be displayed.
Follow these instructions to complete the
procedure.
WARNING: Clear water
When using Autolearn you must have significant clear water both in
front and to the sides of the vessel. This is needed to accommodate a
series of maneuvers, which include sudden, sharp turns.
WARNING: Vessel safety
Press the Standby button to return to manual steering at any time
during an AutoLearn routine. NEVER compromise vessel safety.
