...it did and thank you for that.
ANSA is correct. Further more, it could be argued that Australia has already fallen behind the leaders of ADS-B and that Europe now is technologically and operationally in front of the pack. We both work in Aviation in the Northern Hemisphere and can assure you that 1090ES is in use globally. It is not DME-A as Mr Smith would have you believe... it is in fact the equivalent of DME-I, because it is now, by default, the International Standard for ADS-B.
Mr Smith et al should be proud of their achievement in delaying/stalling ADS-B in Australia. The danger now is not falling behind, but being left behind... and that, my Antipodean friends, is your choice.
