Narrative:
While briefing the ILS Z 8 to kbur; I referenced the approach note number four; stating that coupled approaches are not authorized below 1027'. In IMC; still coupled at approximately 1200'; the aircraft was at half-scale deflection to the right; trending further right. At this point I disconnected the autopilot; manually corrected the localizer course and continued an uneventful approach and landing. Of note; there was very little wind aloft on the ILS.
