Casper, I agree about the legislation. I was looking up the numerous instruments, orders, regulations, legislation and shiny brochures the other day and it would need a full time two week Air Law course for a new CPL with no legal training to deal with it.
Why ? Look at CASA's purpose - to protect CASA and nothing else.
Also, why no this or that ? That part is not CASA's fault, its because there is NO MONEY IN GA other than that made by the engineers and (some) turbine operators with short term contracts. And where does any GA-sourced money go ? Answer: to higher performing investments outside GA, thats where.
Reducing stuff ups in general ? That comes down to the operator as the second last line of defence in the system, and the individual pilot doing ongoing self education as the last line.
