actual speed, actual ROT in degrees per minute or actual RAD in nautical miles, rudder(s) order,
rudder(s) feedback, and steering method.

These limiting factors can also apply in the Non-Adaptive (PID) operating mode
provided the autopilot has been programmed - for Radius controlled turns - and
that Speed (SOG) input data is available.
