Well Mr Clarke has demonstrated a degree of arrogance that would suggest he could well unleash unsafe aviators. Of course arrogance and an inflated sense of ego is always seen as an asset in military aviation
I'm not sure how you equate arrogance with fighting the ridiculous system of rules that the
bureaucracy called CASA has developed. There are many of CASA's rule set that really need to be tested as they really don't make sense in the real world.
I assume even if he was granted RPL he would still need to pass a proficiency check to be able to use said qualifications. I have many ratings on my licence, some I haven't used in years, so I would have to do a check ride to be able to use them. So having the rating does not equate to unfettered use of such.
