Mr Smith et al should be proud of their achievement in delaying/stalling ADS-B in Australia
...and yet, still no idea just what will happen to GPS when the first GPS guided Buzz Bombs fly over the Australian coast line - Have Airservices planned for such an eventuality ???
(and this is only one scenario)
Australia currently has a very robust air traffic control system run by a bunch of very dedicated, albeit understaffed and overworked, airtraffic controllers. Any terrorist threats to the current radar based ATC system would have minimal to nil impact.
Apart from any terrorist threat, we also have no real guarantees that civy GPS will be available in the future. There appears to be a 'cargo culture' mentality amongst some posters that the GPS signals will forever continue to rain down FREE and unimpeded upon their glorious ADS-B recievers.
... where is the contract guaranteeing ongoing supply ???
If we get ADS-B fully implemented, Airservices will be able to sack many of the airtraffic controllers and close nav-aids and radars.
When ADS-B fails, there will most likely be no real backup what-so-ever
