Well regardless of your opinion that there is no safety case, it seems that 'world's best practice', is to conduct a flight test for applicants for an ATPL. The usual suspects on pprune seem to hold the FAA regs and Kiwi regs as some sort of Holy Grail of aviation regulations, and they both require an ATPL flight test. So when CASA make an attempt to bring the so called 'galapagos of aviation' in line with world's best practice, the same voices seem to chastise them again. Damned if they do, damned if they don't.
