Mr Dick Smith
Is not the Garmin GTX 330ES that was mentioned earlier compliant?
If so, it is nowhere near this $100,000 you quote. One suspects $5000?
You suggest there may be a little extra cost in running dual systems - I question who will pay that cost - does not Airservices raise its operating capital from fees to users?
It is of interest that this 1090ES is considered by you to be somehow at risk of reliability or expense yet is apparently the accepted standard at airline altitudes? Is it not now appearing on ATC screens around the world already?
It seems to me that this ADS-B is a technological development that provides radar equvalence at cheaper cost due to technology. Is not radar over 60 years old? Will we still be keeping our old mobile telefone each time we get a new one (at our cost) to ensure the new one works OK? How much 60 year old technology did you keep in your electronics shops?
I remain very puzzled about this opposition to this technology. On this debate there is much emotion and diversion.
