Some weekend browsing below; it seems CASA have obligations toward RNP much the same as for RVSM. It seems fair to criticise the time and cost aspects of Dicks approval; AUD$ 2000 odd dollars / 160 = 12.5 man hours is an unreasonable add on to the red-tape requirement.
As you can gather from the AC and other information, there is a need to 'satisfy' the legal requirements, but with 'company' documents in order and a factory certified aircraft any more than a days work for one man seems excessive, perhaps a time/motion study would clarify the time wasted, on the telephone, sending e-mails, making coffee, yarning with whoever is sitting about the office. etc. etc..
I can defend the need for some form of 'evidence of compliance', but to charge for a day and a half when six hours of honest work would do the trick smacks of a mini rip off. It's callous manipulation the bloody system again; not the 'rules'.
No matter Dick – Uncle Wazza will fix it – sometime in the far distant future; lash out the rebates and have it all running like a Swiss watch in no time - won't he??
