DODGE KEYS
Pressing either the red or green
DODGE key will dodge the vessel in
that direction.
The display will switch to show the
vessel's rudder angle. Pressing and
holding both DODGE keys will centre the
rudder to hold the vessel off course.
Release the DODGE key(s) and the
vessel will return to its programmed
course.
ALARM CLEAR
The autopilot will sound the alarm
when an error condition exists.
This condition will also be indicated on
the display. The alarm may be cleared by
touching the
ALARM CLEAR
key. If the
error condition still exists, the alarm will
come on again.
RUDDER
Controls the amount of rudder applied
for a given amount of course error.
At the maximum setting of
'9'
, 3 degrees
of rudder will be applied for each degree
of course error. Every two position
reduction in the setting cuts the amount
of correction applied in half.
COUNTER RUDDER
Controls the amount of rudder applied
for a given rate of change of course
error.
If the course error is increasing, the
counter rudder adds to the rudder
correction applied, and if the course error
is decreasing, the counter rudder
subtracts from the rudder correction
applied. At the maximum setting of '9', 10
degrees of rudder will be applied for a 1
degree per second rate of change of
course error. Every two position
reduction in the setting cuts the amount
of correction applied in half.
YAW
Controls the amount of deviation from
the programmed course the autopilot
will allow before correcting the
vessel's heading.
Increasing the setting will increase the
amount of heading deviation allowed.
The number shown on the display is the
number of degrees of heading deviation
allowed, centred on the programmed
course
(i.e. a setting of 4 will allow 2
degree's of heading deviation on either
side of the programmed course, before
any correction is applied)
.
TURN RATE
Controls the rate at which the vessel
makes a course change, returns to its
original course after a dodge, or
changes course under Nav Device
control.
The turn rate corresponding to each
control setting is shown in
Table V
following.
