Sikorsky have made a big deal about RIPS but when the S-92 icing clearance was last covered on this thread there was a limit regarding 'no flight in large supercooled droplets' that was mentioned but never clarified.

Now I believe that large supercooled droplets are what you find in fairly warm icing cloud, not just CBs, so it doesn't sound like much of an icing clearance above and beyond any other helicopter, especially since there doesn't seem to be a device for measuring the actual size of the supercooled droplets in flight (apart from possibly an ice accretion meter a la Sea King or Lynx where you can at least see whether it is rime or clear ice by the texture and opacity).

Would any S92 operator care to comment or elaborate on the actual S92 clearance as opposed to the 'press release' clearance (a bit like the range issue possibly)?
