2. Check that it is safe to turn onto this course.
3. To accept this apparent wind angle, press
standby and auto
together within 7 seconds.
Note: If you do not accept the previous wind within 7 seconds, the
autopilot will lock onto the current apparent wind angle.
Dodges in Wind Vane mode
When the autopilot is in Wind Vane mode you still have full control
from the keypad.
Initiating a dodge maneuver
In Wind Vane mode, you can make a dodge maneuver by using the
course change keys (
-1, +1, -10 or +10) to select the desired course
change. The autopilot will adjust both the locked heading and locked
apparent wind angle.
Cancelling a dodge maneuver
After you have avoided the hazard, you can reverse the previous
course change, or return to the previous wind angle (
LAST WND?).
Wind shift alarm
If the autopilot detects a wind shift of more than 15° it will sound the
wind shift alarm and display the
WINDSHIFT alarm message (see
page 15).
To cancel the alarm and retain the existing wind angle and new
heading:
press
standby and auto together.
Alternatively, to cancel the alarm and return to the previous
heading, either:
adjust the locked wind angle using the
-1, +1, -10 and
+10 keys
or
press
standby to return to hand steering, steer onto the
required heading, and press
standby and auto together to
return to Wind Vane mode with the new apparent wind angle
