Isn't it wonderful that in this 3rd World backwater we have regulators with the foresight to make sure we lead the world by mandating that we fit all of this incredibly expensive state of the art stuff way before anyone else or even before the technology exists in some cases.

Its a well worn soapbox of mine, but we are the only country in the world that is mandating ADSB for all IFR operations (including private) down to ground level.

Within not much more than 2 years ALL IFR aircraft will require a WAAS GPS and Mode S - ES transponder. For anyone with a C129a GPS, this will be about a $25k upgrade.

For most IFR flights under 10,000 ft, ADSB will have NO safety benefit because we must still be separated from non ADSB (ie VFR) aircraft.

The major beneficiary of ADSB are the AsA execs that have been getting seats at the front of Qantas jets to go to meetings.

Akro, ill admit to not knowing what's what and hoping we aren't talking two different things... But yes I am sure we are adsb. Ive got Trig tt22s in the fleet, and centre have commented that seeing us on adsb is very helpful.

as far as i understand, that is adsb out. We have no requirement for "in".

I'm no techno gizmo either, and this stuff confuses the heck outta my limited brain capacity!

Or, we're all flying VFR.
Real safety outcome there.

From the Trig website:

Trig were the first company in the world to offer a ‘mandate ready’ certified 1090ES ADS-B Out compliant solution. The TT22 is popular in the U.S. where a certified WAAS GPS, and a ground air determination device are also required forming the ideal 2020 ADS-B solution.

Note the TT22 is described as "mandate ready" rather than ADS-B compliant.

There is currently some level of debate about whether C129a GPS (eg Garmin GNC155XL) could be used to provide position input for 1090ES ABSB, which is what is currently due to be mandatory for all IFR aircraft at all levels in all airspace and all classes of operation in Australia on 2 Feb 2017.

There is a technical difficulty with using a C129a GPS that I forget. It may be that C146a GPS units have a different data format available to feed the transponder.

I would guess your transponders are operating as Mode S transponders, rather than ADSB transponders.
