Autolearn; Requirement For A Clear Area; Procedure - Raymarine ST70+ Operating Manual

Chapter 2: Commissioning Procedures

AutoLearn

AutoLearn enables the autopilot to 'learn' the vessel's steering characteristics, by
carrying out a number of maneuvers.
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.

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
