Course to steer: 85
The Course Control operation is activated when the Autopilot is in Heading Control
mode and the Course button has been pressed.
When switching from Heading Control mode to Course Control mode the actual heading
defines a Course Over Ground line. This courseline will be the baseline that must be
controlled.
Course control is performed with data from a position sensor and a sensor for
Speed Over Ground data. The Autopilot calculates the distance to the courseline based
on the following data:
-- position
-- Speed Over Ground
-- course trim
-- drift, wind
Other adjustable parameters (like yawing, rudder, economy or precision) are taken into
consideration.
