My sentiments exactly.
If RAAus is so clever and so advanced and oh-so-much better than GA, what would be hard about the conversion?
Either:
1/. Medicals; (fair enough) or
2/. GA looks menacing and scary (an image problem GA would do well to remedy); or
3/. RAAus is run by private pilots and PPL wannabes who want to be able to achieve the 'big' prize with less work.
...or possibly varying combinations of all three.
With respect to
how you can do your GFPT at say, Coffs Harbour, solo circuits and all, with a Student Pilot Licence?
...because such students have a Flight Radio Telephone Operator's
Licence or are working under a CASA instrument permitting RAAus training in that specific airspace.
