What makes a 50 hour PPL any more experienced or educated than a 50 hour RA-Aus pilot.
I noticed that you did not put a question mark at the end of that sentence so I guess that you do not want an answer.
The difference is what is covered during those 50 hours of flying. The PPL may have covered the syllabus for CTA and therefore by definition has "more experience" than the RAA pilot.
therefor the ability is not limited by physics
A specious argument. I am not a doctor but I can take your appendix out in an emergency, say 1000nm out to sea, it would be rough but I could do it, just that damn piece of paper standing in my way back on the mainland.
