Rocket,
There was an email floating around that made fun of pilots understanding the regs.
Fact is no one understands the Regs as they stand today, pilots blunder through because they want to be compliant and really don't want to hurt themselves or others.
CASA use the "system" to maintain the status quo because it suits them to be in a constant state of flux, easier to force those they get a set against out of the "Industry" and easier to maintain their game on the side issuing exemptions.
Lawyers have no desire to fix the situation, for some of them it is a "Cash Cow" with no sight of an end, 23 years in the making under multiple CASA Administrators.
