Spot on, VoR, and thank you for your efforts.
I believe it was only through your well-reasoned, and timely, intervention that the airspace decision makers in Oz finally started to seriously question the bases for planning underpinning NAS and the potential downstream consequences of the path that we were going down. Their task was made so much easier when DS self-destructed on 4BC.
As a PPL who uses the system regularly, thanks for restoring common sense into the debate and for ensuring the ongoing integrity of Australia's national airspace system.
As you say, every system needs to continually evolve and improve, and I believe Australia's system can be improved, but let's do it in a manner that reflects world's best practice in planning methods and also maintains the confidence of ALL airspace users.
