2.5 Using Wind Vane mode
Note: You can only use Wind Vane mode if the wheel pilot is
connected to a suitable wind sensor/instrument providing wind
direction data.
To use Wind Vane mode, the wheel pilot must receive wind
information from one of the following sources:
• SeaTalk wind instrument
• NMEA wind instrument
• Raymarine pushpit wind vane (part number: Z159) connected via
the supplied SeaTalk interface
In Wind Vane mode the wheel pilot maintains a course relative to an
apparent wind angle. The pilot uses WindTrim to eliminate the effects
of turbulence and short term wind variations. This provides smooth
precise performance with minimum power consumption.
Wind Vane mode uses the fluxgate compass as the primary heading
reference. When changes in the apparent wind angle occur, the wheel
pilot adjusts the locked compass heading to maintain the original
apparent wind angle.
In Wind Vane mode, the wheel pilot ignores short-term changes in
wind direction, yet still tracks real wind shifts as subtle as 1°.
Selecting Wind Vane mode
From Standby mode or Auto mode, press
STANDBY
and
AUTO
together to select Wind Vane mode. The wheel pilot will then
maintain the current apparent wind angle.
Note: The autopilot beeps once every 30 seconds in Wind Vane mode.
