Chapter 5: Compass Calibration
Important note
The procedures in this chapter only apply if:
• you have not been able to install the fluxgate compass on a
forward facing bulkhead
or
• the SportPilot takes up an incorrect waypoint heading when
operating in Navigator (Track) mode
Introduction
The SportPilot requires a heading reference to compensate for
Northerly turning errors. In Navigator (Track) mode it also needs a
heading reference to turn the boat towards the next target waypoint.
The SportPilot can usually obtain accurate heading information by
attaching the fluxgate compass to a forward facing bulkhead (as
described in Chapter 4: Installing the SportPilot).
However, if you are unable to mount the compass in this way or if the
SportPilot steers onto the wrong heading, you must carry out
compass linearization and heading alignment procedures in this
chapter. These procedures ensure that the reading from the fluxgate
compass corresponds to the heading displayed by your boat’s
compass.
