Modern A/L works well and not only in fog
The choice about whether to use an autoland system in adverse weather, particularly related to winds, and shear, depends on the aircraft type, installed AFDS, the mode to be used (e.g., LAND 2 versus LAND 3, Dual or Triple Channel, etc) and the relevant AFM provisions.
It is absolutely not true that autoland is intended "only for use in fog conditions".
APs ranging back to the PB100 or FCS-110, and even before as with the SP50 (e.g., Mod Block IV) had reasonably good capability in winds and turbulence. Whereas modern autopilots have terrific robust capability (e.g., B777, B737NG, B757/767, B744 and B748) in winds, shears, and turbulence. I've done successful and reliable A/L flight testing (and also many authority certifications), as well as operational use, with good resulting A/L performance in modern transport jets, in winds, shears, and turbulence conditions that otherwise would water the eyes of a pilot even attempting to land manually in those conditions, even if in CAVOK. The rule of thumb is fly within bounds of the approved AFM, and within any applicable operator specified policy constraints, ...and A/L will provide safe and reliable service, particularly in modern civil transport jets.
