Simrad AP50 Autopilot
142 20221032B
Selecting the boat type and length has set default values for
these parameters (Installation Dockside menu). Before doing
any parameter tuning, check if the boat steers satisfactory with
the default setting (can be checked as described under Manual
Tuning or by normal Auto steering).
Recommended speed during Automatic tuning varies with the
type of boat, but it should not exceed 10 knots.
Note ! Automatic tuning should not be performed at planing speed!
For displacement boats, use a speed that is approximately half
the normal cruising speed (i.e. if cruising speed is 10 knots, do
the Automatic tuning at about 5 knots).
If possible, perform the Automatic tuning steering East or
West, as this will yield the best-balanced parameters.
WARNING ! The Automatic tuning function will take control of the boat
and perform a number of S-turns. It must always be
performed in open waters at a safe distance from other
traffic. The Automatic tuning function may take from 1 to 2
minutes to complete. To stop the Automatic tuning, press the
STBY
(STBY) button.

Activate Automatic tuning by rotating the course knob
clockwise.
After the Automatic tuning has been completed, the autopilot
will return to STANDBY mode and the rudder must be
controlled manually.
When the Automatic tuning has been completed, there should
be no need for further adjustments to the Rudder and Counter
Rudder, but the speed response must be set. However, on
certain installations, you may want to "fine tune" the parameters
after the Automatic tuning due to special steering
characteristics of the specific boat. One may view or change the
Automatic tuning parameters in the User Set-up menu (see
page 39).
