In this context, "may" == "is allowed to".
No it isn’t.
In this context “May” is “Expressing Possibility”. It is a deliberate use of the word and allows CASA a wide interpretation as it has done through the AC. Another word that is littered through the CASR is “Should”. These worlds don’t imply anything but give incredible flexibility to the regulator in how they interpret them. CASA’s interpretation is in the “Advisory Circular”.
