The rose colored "vision splendid".
Spikey, Spikey, Spikey, I want a pint of whatever your having, must be good stuff. Only a CASA zealot or a naive newcomer to the industry would even give two minutes of credence to your "Babes in toy land" beliefs. Benefit of doubt rule applied, once.
"As long as the regulator sees that there is at least an equivalent level of safety to operations under existing legislation and there is justification supplied and argued effectively by the operator for the change then it will be accepted. FRMS is a case in point".
Bollocks. Who defines the "equivalent" level of safety, who decides if it is justified, who decides if an argument is effective, who decides to accept the changes, the bloody reg's don't. So, it's left even more wide open to individual interpretation, arse covering inevitably follows. Stupid changes enforced to make the Administrator feel warm and comfy. Nothing even remotely like your whimsical scenario will occur as long as there is stark reality, human nature and one serviceable aircraft on the planet.
Read Sunfish for reality fix, read Lead Sled for the 'way things are' fix. Take a back bearing on that, then talk to some operators, if they know and trust you, you'll get a shock. Then come back and tell us a 'true' believers tale of truth, justice and the Australian CASA way.
