I'm not normally known for giving any latitude to CASA, however, I think you may be a little unjust on BB in your last post.
The regulatory reform process is, I believe, something like a supertanker. To get it to change direction is a massive operation that takes time and distance and there is still a lot of resistance within CASA to being told to change.
That said, I still think they may be better off adopting something like the FAA regulations and make as few changes as possible to suit Australia and our legal framework. I doubt that CASA has the expertise to complete the process and produce a satisfactory outcome.
