Selecting a different navigation source
If you have more than one navigator connected to the
AP28, you will be able to choose any for navigation. Refer
to the ‘Sources’ item in the Setup menu for details on
how to select a different navigator (page 58).
2.8 Wind vane steering (sailboats)
The WIND mode is only available if the system has been
set up for SAIL-boat in the Installation Menu.
Prior to entering WIND mode the AP28 system should be
operating in AUTO, with valid input from the wind
transducer.
Enter the WIND mode by pressing the WIND key.
The wind display presents the following information:
WIND
• Wind (vane) mode
• Set wind angle: 008 degrees
from starboard
• Measured wind angle: 008°A
(apparent) or T (true)
• Course to steer (to maintain
set wind angle): 345°
• Heading: 344° M (magnetic) or T (true)
• Rudder angle: 00° to starboard
• Speed from log: 12.8 kn
• Parameter: LO-A (Low value, automatic set)
The set course to steer (CTS) and set wind angle are
entered from the compass heading and the wind
transducer at the moment the WIND mode is selected.
From that point the autopilot will change the course to
maintain the wind angle as the wind direction may change.
If the cumulative shift of the wind direction exceeds a set
limit a WIND SHIFT alarm will sound.
