LeadSled, the third tier of regs being called for, as I understand it, is that the convoluted legal waffle that is Part 61 etc be translated into plain English, so bring it on, I say. Nobody wants more regulation; I just want whatever we have at any given time to be clearly expressed.
We already had that kind of thing with the Act, CAR and CAO, but something more straightforward would be welcome.
Sunfish said something along the lines of 'CASA will issue / approve etc' would be used in a sane country; in fact a fair number of the new regs do read along those lines.
The Part 61 MOS is pretty shabby in places, but they're reviewing and re-issuing it soon apparently, so I'd expect some of the clearly wrong bits to be fixed.
