Do the controllors responsible for traffic information to IFR aircraft at Devonport actually see an ADSB return on their screen in the Melbourne Centre?

If so - to what level AGL?

Has AsA ever released a map of the Multilateration/ ADSB stations in Tassie? I don't think so. Why would this be?

Ten seconds on the ASA website:

ADS-B coverage | Airservices

The evil empire at ASA, withholding information, secretive.

This is year 5 research effort. I reckon a bit more is expected of Chairman material.

Why don't you ask Airservices?

Bloggsie,
You really don't get it, do you. The FAA ADS-B coverage now in place ( have a look on the FAA web site, 600+ ??, I haven't checked recently) gives coverage to low levels, effectively ground level in medium/high density traffic areas, throughout the lower 48.

The reticence of the airlines to spend billions to make the 2020 mandate is quite transparent, nobody has demonstrated to them what the cost/benefit results of spending all this money is going to produce. Hence the ATA lobbying to delay the mandate, they would like to spend their money on something with a return on capital.

Given that shortage of runways is the main generator of traffic bottlenecks in US or Europe (or AU, for that matter), any realised benefits of ADS-B on en-route operations are marginal, at its most optimistic.

That GA in Australia is going to be forced to wear the costs of a far broader ADS-B mandate than US or EU, despite minimal traffic levels, can only be justified in the dictatorial Australian approach, devoid of genuine risk analysis, let alone cost/benefit justification.

If there was a supportable cost/benefit case, AsA and CASA would be shouting it from the rooftops.

Tootle pip!!

Growy. That chart is not clear re Devonport. Does anyone know what the ADSB useable lowest level is at Devonport? . Or doesn't it work at all there?

Marge and Sir Angus are waiting to take your call, Dick :)
