Align engines to center position; "zero rudder".
Rev engines to 3-4000 rev/min and observe the
rudder angle indicator on the autopilot, a 2°
change in the reading should be accepted.
If the rudder angle exceeds 2°, connect the screen
on the TB1 cable (LFI3000) to the center block
terminal and repeat item 2 (Refer to the
AC12/AC42 Installation manual). If this gives a
better result keep the screen connected.
