Until the actual instrument by which the IMCr is grandfathered is enacted, there can be no certainty.
I take it that means 'no one knows'.
Timothy, it's not that people aren't interested in AOPA etc, it's just a matter of time as someone has already said. I have a busy life, I'm sure most people here do. There are only 24 hours in a day. You have chosen in your spare trime to become involved in aviation organisations, I do other things in other fields that are worthy pursuits. I don't see anything wrong in asking people who are in these organisations for a concise reply to a question when with the best will in the world I wouldn't have the time to wade through a mountain of legislation.
I certainly don't denigrate the efforts of the CAA either. Our CFI is a 'wheel' there and I know the amount of stuff he has to wade through.
