The problem is if you spend an hour on CASA website they don't clearly define it either...they have lots of legal documents for pointing the finger at organisations, but they have very little in in the way of actual suggestions that can make a real difference...
One of the major problems I see in all areas of aviation, is everything is so over complicated, that only those flying for a living can even retain 1/5th of the rules, regulation, procedures, skills and processess.
Thus the only way CASA and RAA can make a real difference to us is to break it down into manageable chunks that are desperately needed. You cant teach a kid basketball , if you sit them down and give them 50 years of basketball history, every stat ever fromt he game, every skill, every tactic, every cheat available etc...you get the point... The human brain can only retain so much information.
The key to retaining information is training, repetition and continued learning.
The problem we face as recreational and even GA pilots is this is only one small part of our complicated and busy lives. While we are making it a focus to pass exams , we attain a certain standard, but as soon as we go back to normal living we lose most of that knowledge ...
The best thing CASA and RAA can do is work out whats really critical and reinforce reinforce reinforce those aspects after initial training has finished.
Its the same in driving, first aid or any industry that's complicated or changes continually... the problem is though in aviation, is that they take a lecturing and enforcement approach, rather than a coaching and open approach...
If CASA came up to you and asked hey tell me about your recent flying mistakes and what you suck at , you would shake in your boots and expect to have your licence revoked...where as when a sports coach does the same , most athletes willingly discuss what they need fixed and go about having it corrected.
If they really want to change the Human Factors, they need a cultural change that focuses on being able to express your weaknesses, mistakes and medical issues without getting clubbed to death like a baby seal.
