Colleagues who have flown both the S92 and the EC225 almost universally agree that the EC225 has the more capable autopilot. It "protects the flight envelope" (keeps everyone safe) to a very high standard.
The recently released TSB report on a S92 auto-pilot mishap just shows where the training on that type was lacking IMO. Here's the link to the report.
Transportation Safety Board of Canada - Aviation Investigation Report A11H0001
There may be a separate thread on this already, but thought I'd post it here seeing as we're discussing various types and AP modes.
(EDIT: I see the link was already posted, I just hope it doesn't take 2 years for the AAIB report to come out. I know a few of the pax who were on that flight and to say that they needed replacement underwear is putting it mildly]
Safe flying
