RE: The whole B1/B2 thing.
B2's are a minority in the new world of aviation licences for a reason. B1's can sign for almost all of the typical jobs that get done on this new breed of aircraft. It's just a quirk of the Australian system that our government body is as usual about 10 years too late to get on board what works very well everywhere else in the civilised world.
It does make sense to make the vast majority of licences on the 380 B1 because there simply isn't the work to do to keep the B2's gainfully employed from a manpower perspective.
If you want to argue about that, have a look around the world and see what Qantas are now modeling their licence requirements around. If it works well for everyone else, what makes us different here ?
We should feel somewhat lucky they haven't implemented the A licence's, there wouldn't be much B1 training going on at all in that case.
