Having flown the PA46 in crosswind conditions during low vis approaches I can confirm its auto-pilot performance was not that spectacular low down on an approach with a crosswind.
ATC never trust an autopilot
always be prepared to disconnect and hand fly and always keep current on hand flying so you can do it as well as the autopilot especially in IMC
Its an aid to your superior skills not a replacement for a lack of skills and the reason for many accidents by reliant pilots
As a good pilot i am sure you agree )
