No Dick, they're IFR category, VFR procedures. I doubt high cap in the States would depart VFR and then do IFR pickup.
But Cap'n, what you do is go over to the States, chat to the airlines that run high cap and ask them what procedures they use, you then ask a bunch of line pilots how they apply the procedures. You also talk to the FAA, look at the mandated procedures, chat to a bunch of controllers and go from there.
What usually happens in ASA is that washed up, and/or ex-controllers with very little console time (ladder climbers) concoct Australia's 'own brand' of Class E. And SAFIS, whatever TF that garbage is.
