SPECIAL TURNS
When the autopilot is in the PILOT mode, pressing the TURN key followed by either
the red or green ARROW key initiates the PRE-SELECTED type of special turn.
EMERGENCY TURN
The Emergency Turn is selected by
placing the autopilot in the
STANDBY
mode, pressing the
TURN
key, followed
by either the red or green
ARROW
key
until the display shows 'E.trn'. This turn is
sometimes called the 'man overboard
turn' or 'Williamson turn'. If the vessel's
speed and turn rate are not changed
while the turn is in progress, the autopilot
will bring the vessel about in such a way
that it retraces its own path in the water.
An Emergency Turn to port is
initiated by placing the
autopilot in the
PILOT
mode and
pressing the
TURN
key followed by the
red
ARROW
key. The autopilot will make
a 90-degree turn to port. When that turn
is complete, the autopilot will
automatically make a 270-degree turn to
starboard. The function indicator will
change to an 'E' until both turns are
complete. When the second turn is
complete, the vessel should be retracing
its own track in the water. Pressing the
TURN
key followed by the green
ARROW
key does the same thing only
the first 90 degree turn is to starboard,
and the second 270 degree turn is to
port. The speed at which the turns are
performed is set by the Turn Rate
control, and should not be changed
during the turn (otherwise the vessel will
not end up on its own track).
CONTINUOUS TURN
The Continuous Turn is selected by
placing the autopilot in the
STANDBY
mode, pressing the
TURN
key, followed
by either the red or green
ARROW
key
until the display shows 'C.trn'.
A Continuous Turn to port is
initiated by placing the
autopilot in the
PILOT
mode
and pressing the
TURN
key followed by
the red
ARROW
key. The vessel will turn
at the rate determined by the Turn Rate
control and will continue to turn until
either the red or green
ARROW
key is
pressed. The function indicator will show
a 'C' until the turn is stopped. The vessel
will then travel in the direction indicated
on the display. Pressing the
TURN
key
followed by the green
ARROW
key will
start a similar turn to starboard.
