Then the system would work as if covered by SSR without the cost of the as yet uncertified ADSB.
Given ADSB is currently in use (high) (and low near the box sites), surely it must have some sort of certification/sign-off for operational use?
There still is no radar "replicating" standards, is that what you mean?
I understand that some MLAT sites were not secured, ie not leased correctly or sites without power etc. so the units were not deployed; some rumour about using some of the units for the SY PRM replacement project too.
Also heard issues with turning the current LT head off with or without MLAT use; but not clear about it. Something like turning the radar off before turning MLAT on.

Its kinda hard to believe that in 2008 (did you get that?).....
..... 2008 ! .....
...... you can depart YBUD and not be identified on radar until you have climbed through about 6000' !

The boxhead who posted two before me is still fighting against this astounding leap in capability and efficiency.

Unforetunately, ADS-B doesnt work without GPS - I think all it will take is one miss-use of GPS and that is the end of ADS-B.
Jumpu, If the AA low level ADSB proposal is so good why is it that they are not going ahead with it?
And don,t say it's because of me. Thats rubbish!
And why are they installing a multilateration system in Tasmania if ADSB is the way to go?

Could it be something to do with ASA trying to find a way not to spend the $$$?
As for Tasmania, probably the reason ADSB is not being used there is because until the full fleet is fitted, both the smaller RPT and GA, the ADSB screen would be blank!
If they just did the whole thing and did it properly, put systems in place to ensure integrity, I am sure all would be better off.

ADS-B and normal Mode C?
Does the ADSB system interogate normal Transponders as well?
I've noticed on recent trips to TNK the 'R' flashing in the Garmin transponder display as if it's still identified on radar. On the NOTAMs TNK is listed as a recent site addition for the system...
If so can ATC see anything on their screens?

The Flashing R (assuming regular non mode S - transponder) is more likely to be TCAS interrogation from those above.
Plazbot, stop encouraging the terry towelled hat wearing flat earth society.

This Flying Binghi dude seriously must spend all day looking over his shoulder. US turning off the power, terrorists guiding missiles through his window, Peak Oil theory.
Let's keep semi on the topic with HBA in particular. Am I right that there is no VHF on the ground there as well?

I agree with Flying Binghi, anything could happen, absolutely anything, can't trust them terrorists...
Therefore Binghi my mate, replace that wooden rear door of yours with a reinforced steel door, weld the shutters over the windows, replace the insulation in your roof with Aluminium foil (no gaps!), pour some David Gray's Dusting Sulphur into a tin can and wire it up with a flash cube to the security light over your front door, sandbag the perimeter of your property and put two rows of Cat 3 wire in the frontyard channelling into the porch where you can sit with your pump-action on a rocking chair and listen to your Chiuaua take on the world as it passes by...

I'm not at work, but is TNK Tennant Creek? If so, you're in an area that is full of both airborne and ground military radar equipment that could very well be interogating your transponder.

GPS is vulnerable to geomagnetic storms which could put the system out for up to a couple of days.
The satellites are presumably designed not to be permantly affected but we haven't enough experience to know how strong they can really get. So all the satellites could suddenly cease to function.

Jumpu, I "Googled" Project Atlas and this is what it's all about:
Project Atlas of the Department of Mental Health and Substance Abuse is designed to collect, compile and disseminate data on mental health and neurology resources in the world.
What are you saying about Dick?
Di
(just kidding Dick!)

This sounds like a good solution. I think the trend is for more jet services into HBA...expanded services from Sydney & Melbourne as well as a new 900m cross GA runway.
From the Hervey Bay Council Airport Masterplan media release 13/3/07...
http://www.frasercoastairport.com.au...ter%20Plan.pdf
"The master plan includes provision in the future for more car parks and
security parking, a 900 metre cross runway as well as room for three or
four jets to be parked at a bigger terminal that will cater for the expected
growth in tourism."
This inevitably means more traffic, heavy and light. Most ultralights don't even have Mode A/C transponders let alone Mode S or 1090 Extended Squitter. Figure on a not inconsiderable proportion of the increased traffic being of the ultralight variety. This is no place to have a SSR hole or, for that matter, no place for any aircraft without a transponder...IMO.

An Aviation Advance, Cleared For Takeoff
Some quotes from a CBS story -
I can't see any planes," said Capt. Karen Lee, a veteran 747 pilot and director of operations for the world's 9th largest airline. (That would be UPS.) Commercial jets like hers do have a little screen that warns of imminent collisions, but it's crude, and not designed for navigation.
Is she talking about TCAS ?
So who would not love ADS-B? Who could possibly object?
And the UPS trial wasn't ADS-B's only success. The FAA also tried it in Alaska, where a lot of area has no radar services, presenting a very challenging environment for pilots.
And what were the results?
"We've reduced the fatal aviation accident rate in those particular areas on the order of, like, 38 to 40 percent," Capezzuto said.
Was that a reduction in mid air colisions due to ADS-B ????
