This thread is in the RA-Aus forum section but I believe it is important enough for ALL members to start doing some serious research, some serious thinking, and taking some serious action about this one. Below is a copy of my post in the RA-Aus section of this forum.
ADS-B
Automatic Dependent Surveillance – Broadcast
Airservices /CASA (my Mistake both names are on the consultation paper http://casa.gov.au/newrules/airspace/jcp/jcp.pdf) are pushing ahead with ADS-B (a type of upmarket version of Flarm used by gliders and some ultralights at mixed airfields) This, in its current form, I believe, will be VERY BAD news for us. By 2012 all aircraft entering CTA will be required to have ADS-B fitted, and by 2014 all aircraft in CTAF® will require ADS-B.
CASA policy is to make all aerodromes that have a visit from one or more 10 seat aircraft per month a CTAF®. So starting 2014 if you want to go into or through a CTAF® you must have ADS-B, and by then most of the airfields we currently fly at or near or through will be CTAF®
The “estimated” cost of these units is $10,000 to $15,000 plus instillation?. They can only be repaired by a CASA approved Radio Tec. They will also need to be serviced every two years by an approved Tec. Most of us can’t fly our aircraft into Brisbane or some other major center for a service, So if you can’t put your plane on a trailer, think of what the call out fee might be.
There are suggestions that the government may cover the costs for the initial instillation for currently registered aircraft but not for any new aircraft in the future. But even if we get a “free” unit, the upkeep could "bankrupt" many of us. We will also sell out all our future members of RA-Aus, or if you belong to AOPA, SAAA etc, your future members, if we accept this in its current form. Also no one seems to know how big or how heavy these aviation units are or what their power consumption will be. There will be exemptions for aircraft with low battery capacity or no alternator etc, plus other undefined aviation uses. You could have airspace full of, say, gliders, hang gliders, paragliders etc but banned to ultralights. If so what is the point of having them compulsory outside of CTR.
Also, as I read the new regulations, If you don't have ADSB you won't be able to fly above 5,000 ft (QNH) regardless of the terrain.
My personal view is we need to lobby to at least stop them from being compulsory in CTAF®, and below 10,000 ft.
In the marine field this system is called AIS (no height requirement) and has been in operation for some time, and I guess is where the Aviation idea came from. This is now mandated for commercial shipping but you can buy pleasure craft versions of AIS for under $1000, which use is voluntary. Also non AIS equipped pleasure craft are not excluded from shipping lanes where AIS is compulsory for commercial shipping. Eg The narrow shipping lane up Cape York Peninsular. The great "sell" on the safety aspect of AIS doesn't gel either. Just look at the serious big ship collisions in the English Channel in recent years with ships fitted with AIS and all the alarms (TCAS equivalent). There is no real substitute for "see and avoid". Only aids to help you.
Also if any of you people out there have a "thing" about your personal privacy in sporting or pleasure pursuits, be advised that every single move you make in your aircraft fitted with ADSB, from key on to key off, will be tracked, recorded and logged by the government agencies. (track, height, time, bearing, speed, landings etc). If your IQ is greater than 10 you can work out future possible ramifications of this.
The military have rejected their compulsory instillation for now. My personal view is we should do the same under the current proposals.
