Well
Had aa channel or 2 drop out on a SPZ 7000 on a A model in IMC with 8 pax on board. On a few different occasions .It was a little wiggly and took some passing control back and fourth as the leans began to step in but it was not uncontrollable. Interestingly enough the A model didn't have an AP and we spent the better part of our days on the dials in IMC. Never had to land until we " practically" had to.
This automation business is great when it works, but there is still a requirement to fly the helicopter - it's what pilots do!!! It's important that any pilot who has such a big responsibility in a larger transport category helicopter has a great deal of hands on flying experience several 1000 hrs and has faced many non scripted emergencies, under different meteorological conditions and operating theatres . Then and only then should they be permitted by industry to fly the big stuff.
I guess at the end of the day the mystery will be solved. Still no new ASB's ADs or out from The authorities on this issue.... Hmmm.
I am thankful though that no one died! Certainly seen too much of that over several decades.
Stay safe over there!
