ST290 Instrument System Owner’s Handbook
To adjust the cruise speed:
Turning error correction (T150 and T400 systems only)
Turning error correction allows the autopilot to compensate for heading
errors, which are caused by the increasing dip of the earth’s magnetic
field at higher latitudes. The increased dip has the effect of amplifying
rudder response on northerly headings in the northern hemisphere, and
on southerly headings in the southern hemisphere.
