Just have a look at the number of airports that are members of this association will answer any doubt.
Remember this CTA push is ONLY about RPC holders and RAA Reg qualifing aircraft ALREADY have access, have had for years.
If anyone thinks they are going to get CTA without a CASA medical, at this stage anyway, are in a different world to me.
RPC with a CASA medical is effectively a RPL, already available.
