Great to see Australia has again failed to learn from overseas. Here is proof that the ADS-B mandate was a complete waste of everyone’s money because the airspace structure wasn’t updated to reflect the improvements in the surveillance.
I was part of the NAS team all those years ago. The arguments thrown at us back then as to why the US NAS wouldn’t work here, specifically low level E and the US CTAF, was because of their better radar coverage at low level. Well now we have the improved surveillance without any other upgrades and what’s the result?? No change. What a surprise.
