Missy, you make a fair point. Perhaps that is what we dont currently have? When I wrote the post I had Class G airspace at Ballina, Dubbo, West Archerfield and Wellcamp in mind. All the same classes of airspace, all have different levels of, accepted, associated risk. (They are accepted because they are published. Someone must have accepted that risk, right?)
I think your point is they should all have the same target risk level. We need to establish what that is, and provide the enabling technologies to achieve it.
