Being a "Professional " aviator is more than just getting an aeroplane from point A to B in one piece. Keeping track of changes in the industry and taking the time to provide input to the various consultation processes are professional traits.
CASA typically offer 2 weeks for an operator to read and digest these things and then formulate a sensible, considered, measured response that might actually be "Constructive".
If you think this is reasonable or realistic, you have obviously never owned/operated a GA business.
GA pilots are typically either young blokes going somewhere with their careers (who have better things to do with their time, like drink beer and have sex) or tired old bitter twisted GA codgers like you & me whose responses come across as... well, tired, old, bitter and twisted.
I have never ever actually had time to make a response to any of their crap. Sadly perhaps. Perhaps not.
