Transition HI-LO
The Transition HI-LO is the speed at which the AP24 will
automatically change the steering parameter set from HI
to LO parameters, or vice versa (page 13).
The defaul
t setting of the Transition speed is 6 knots.
On power boats it is recommended that you set the
Transition HI-LO to a speed that represents the speed
where the hull begins to plane or the speed where you
change from slow to cruising speed.
On sailboats the Transition speed should be set to 3-4
knots to give the best response in a tack.
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/chart
plotter.
See also page 13.

Automatic tuning
Autotune is a feature that automatically sets the most
important steering parameters (Rudder and Counter
Rudder) by taking the boat through a number of S-turns.
The scaling factors of the parameters are also set
automatically as a function of the boat type selection
performed in the Dockside menu.
