Figure 96 – WORK Mode Menu
Rudder Bias
This menu line only appears when WORK mode is active. It shows the current rudder bias,
which can be adjusted if desired.
Autotrim
The autopilot’s WORK mode can be configured to use manual or automatic rudder bias trim
when in WORK mode (the default is to use automatic bias).
Manual rudder bias is fixed by the position of the rudder when the autopilot first enters
WORK mode, but can be adjusted by the user if desired (see Rudder Bias , above).
Automatic rudder bias is initially set to the position of the rudder when the autopilot first
enters WORK mode, but is automatically adjusted on a continual basis thereafter to ensure
that the boat remains on-course.
Work Trip Pt. (Work Trip Point)
This is the speed below which WORK mode can be engaged, and above which WORK mode
will be disengaged automatically. The value can be 1 to 10, and is in the units that the
Speed Source (see the Auto menu) is using.
Rudder Scale (Rudder Scale Factor)
When WORK mode is engaged, the Rudder Scale Factor” will multiply the Rudder Gain
setting in the Auto menu. Normally, the rudder is moved an amount proportional to the
course error detected (i.e., the error times the Rudder Gain, and using some constants which
depend on boat type), but in WORK mode that amount will also be multiplied by the Scale
Factor. This will always resulti in larger rudder movements for a given course error
Work Mode State
This parameter shows the current status of WORK mode. It is also a means to force WORK
mode to be active or not. Normally, WORK mode is engaged or disengaged depending on
the speed of the boat as given by a Navigation System. In cases where this information is
not available, WORK mode can still be made to function by forcing it on.
The states shown are “Off”, “A_On” and “A_Rdy” (abbreviations for Automatic On &
Automatic Ready, respectively), or “M_On” and “M_Rdy” (Manual On & Manual Ready).
