Is it worthwhile trying to get any sense out of CASA? There are some good people there.
The main trouble I've had is nobody will make any decisions, they just quote regs and say put the question to somebody else.
If it's anything like the rest of of their changes of regulations that are supposed to be interchangeable or direct replacements to FAA or JAA stuff, never happens, look at part 61. What a disaster, all it's done is make anything to do with a licence a lot more expensive and complicated.
