After an Automatic tuning, there should be no need for further
adjustments. “Fine tuning” of these parameters are made by the
response control (see page 42). However, viewing or changing
the parameters can be made from within the Parameter menu
item
. See also “Recall Autotune” on page 84.
Proceed to the next menu item by pressing the STBD button, or
return to Standby m
ode by pressing the STBY button.
Transition Speed
The transition speed is the speed where the AP25 will
automatically change the steering parameter set from HI to LO
parameters, or vice versa (page 17).
The default setting of transition speed is 5 kts.
It is recommended that you set the transition speed to a speed
that represents the speed where the hull begins to plane, or the
speed where you change from
slow to cruising speed.
The speed used for the automatic transition is obtained with the
following priority:
1. Speed through water from the speed log source.
2. Speed Over Ground (SOG) from the GPS/Chartplotter.
If no speed data is available, manual speed selection is required.
See also chapters 2.8 and 2.9.
Rotate the course dial
clockwise until the transition
speed is set to the desired
value in knots.
Range: 00 – 30 knots
Default: 5 knots
