James Michael, just because Garmin has a remote squawk entry via the G1000 and GNS480, it doesn’t mean that the unit transmits certified ADS-B data. In fact it doesn’t.
My suggestion is that you place a phone call to Garmin (or their representative in Australia) and ask if they have a certified ADS-B unit that can be installed in your aircraft. Get the price of the unit and the price of the installation, then post the result here.
Capn Bloggs, the ADS-B flight testing which is being undertaken in Florida is a completely different system to the one Airservices is planning here. This is my very point. Wouldn’t it be better to be a little conservative, wait a little while, and install the system which the majority of the world goes to? Then the prices will be substantially lower and the support for the system will be substantially higher.
Phew they missed!, if there is a measurable safety problem – or an efficiency problem where aircraft are delayed in the WA mining area – surely that will be substantially solved by the high level ADS-B project. These high level transceivers are already being installed and will give coverage in the higher level controlled airspace in WA. If this is so there will be a substantial reduction in cost compared with spending over $100 million in subsidising aircraft in the east – where there is no measurable safety problem.
More importantly, why not use the multilateration transceivers – similar to those being installed in Tasmania – in the west? Then the whole system will work with standard transponders with incredible accuracy, without reliance on GPS, and at far lower cost.
