It hasn't been called Alteon for quite some time. I did my conversion at Boeing Flight Training Brisbane about 2 years ago.
If you're used to a well structured ground school, you won't find it here. BFT isn't a shadow on the Qantas group-style of ground training. With that in mind, if you can get the CBT, do it at least once beforehand.
However, it's the sim instructors that put in the work and make the course worthwhile. The two blokes I had dealings with were both experienced on type, and quite knowledgeable.
Bob Cox was my main instructor, and very good IMO. Ed Field did my check, and once again - pretty good. Both realistic in their expectations of the trainee.
But, as for all courses- you get out of it what you put in, so do the work. It wasn't a walk in the park for an old coot like me....
Remember the 6 P's.
Good luck with your course.
