Whilst I don't disagree with what you're saying, you could use any aircraft for ATPL flight planning and the concepts would pretty much be the same. So I don't see what benefit changing the type of aircraft would have, other than costing more money which CASA already swipes from us.
Agree with you on that one, but if CASA are so hell bent on changing the foundations of aviation regulation they could at least make some attempt to keep the training syllabus in line with the changes.
Last time I checked there was not even a mention of ADSB in the current IREX syllabus which CASA deems to essential for 'safe' IFR flight in Australia.
