James Michael, I’m sure in the future Garmin and similar GPS units will have the necessary software to translate ADS-B into a TCAS-like use. The problem is that it doesn’t exist at the moment, and I would rather wait until the bugs are ironed out.
I will say again that I’m a total supporter of ADS-B. I’m just not keen on Australia leading the world. I would rather the costly errors be made in other countries, then we reap the benefit of their learning experience.
I cannot see any immediate safety problem that would require VFR aircraft which fly in the low levels to be fitted with an expensive ADS-B ‘out’ unit.
Considering that Airservices is spending a lot of money on a multilateration system in Tasmania that only requires Mode C or Mode S transponders to work satisfactorily, I cannot see the enormous hurry to go to a subsidised ADS-B system for GA.
I have always been cautious and conservative in my business dealings, and this has given great benefits.
