Chapter 5: Adjusting Autopilot Settings
5.1 Introduction
This chapter is intended primarily as reference material to provide an
overall picture of the autopilot calibration settings you can adjust to best
suit your operating requirements, and to give details of the autopilot
factory default settings. You will have adjusted many of these settings
when commissioning the system, and they should not require further
adjustment.
Note: Before adjusting any calibration settings, complete the commis-
sioning procedures described in Section 8, Chapter 4.
Calibration groups
There are three pilot calibration groups, namely PilotBasic, PilotSeatrial
and Pilot Advanced Calibration.
Each calibration group uses a series of screens to set calibration values.
The exact structure of each group is dependent on which Vessel Type is
selected in Pilot Advanced Calibration. For example, if POWER BOAT is
selected, some options relating to wind settings will not be available.
Pilot Basic Calibration
The Pilot Basic Calibration settings are those you may need to change on
a regular basis, to optimize performance in changing conditions.
Pilot Seatrial Calibration
As Pilot Seatrial Calibration is specifically designed for use during the
initial autopilot seatrial (see Section 8, Chapter 4), you should not need
to change these settings during normal autopilot operation.
Pilot Advanced Calibration
Pilot Advanced Calibration has a significant impact on autopilot
operation and can affect your boat’ssafety. You should not normally
need to alter the Pilot Advanced Calibration values, once you have
completed the initial installation and seatrial.
Pilot Advanced Calibration should be carried out only by suitably-
qualified personnel. DO NOT attempt to use these procedures if you do
not have an in-depth knowledge of setting up Raymarine autopilots
