CaptainMidnight, I actually said that the ADS-B being installed by Airservices Australia would allow aircraft to be tracked and would not be immune to ‘spoofing’ by terrorists.

I understand this is completely different to what the USA is planning. I believe it has been posted previously on this website that the FAA Administrator has said that any system they go ahead with will have a system to detect/prevent spoofing. This can be done with a form of multilateration where a signal must go into a number of ground stations at the same time and be 'timed'.

No real news from me people but I am now using ADSB in as well as TCAS. They are both displayed on the same screen and I much prefer the ADSB given the amount of information I am able to glean from the specific contacts. My TCAS just gives me a number whereas the ADSB gives me names, speed, alt and trends. That and the range I get when I'm up high means I have very nice situational awareness, of the aircraft with these buggers fitted. All in all it's a whizbang little system and even though it's only grabbing the heavies it works a treat.

HOORAY, tell us more of your experiences Whiskey. FACTS will far outway what some people "believe".

And also posted previously on this website Airservices also has in place security measures to prevent spoofing, which presumably you are aware of hence not following up on your demo.

And as far as I am aware, current airborne ADS-B systems can be tracked by suitable receivers and software, hence the populatory of the Kinetic Aviation gear for flying clubs, flying schools etc. etc. I'm not aware of any plans by anyone to implement an encrypted ADS-B system that only ATSPs and other "authorised" agencies can decode. Such a system would prevent other aircraft from decoding the broadcast, which would defeat one of the main purposes.

I really don't know where you are trying to head with your knocking of the system currently being rolled out in Australia.

Airservices and Wide Area Augmentation System
Many may not have seen the excellent article written by Peter Wordsworth in relation to the Wide Area Augmentation System (WAAS) and why Airservices don't seem to be heading in the US direction.

It makes really interesting reading and can be seen here. http://mooney.org.au/files/GPS-the_WAAS_that_WAS_.pdf

Garmin 530/430
 

Dick,
You seem to be a man of quality research in persuit for your Mustang. Question for you...Does Garmin have an stc for there 530/430 retrofit installation on Part 25 category aircraft? I recently got shot down for the install at an aviaonics shop in CO for a WAAS enabled 530/430. They allow the non-waas 530/430 instal though.
