message: "The ongoing debate amongst hobbyists is to display real-time activity on personal screens and then delay five minutes on networked displays." This sentence is inaccurate. To provide 5 minutes delay on networked display is a practice. If that practice is debated, it would be useful to know what the other sides of that debate are.  —Preceding unsigned comment added by Armence (talk • contribs) 22:25, 4 October 2010 (UTC)

message: How does the FAA actually plan to safely control traffic using this system?  I'm a controller and I have flown an airplane with ADS-B, while it is a useful tool for pilots, there is no way it should be used a means of separating air traffic.  If they want this system to work, every aircraft would have to have this costly technology installed.  Even then, air traffic controllers would still be needed to work the traffic, this system is only replacing radar signals with satellite.  The person responsible for this scheme is FAA administrator Marion Blakey, who recently announced she was going to work for Raytheon after her term in office ends.

replies: text: It is not meant to be a replacement for the current ATC system. It is only to be used as a supplement, and mostly in areas that need. Some examples include: in Alaska, the mid-west, and other moutainous areas where radar is limited. Also, in congested areas not assosciated with airports, such as high-volume training areas (like all of Florida). This technology is mainly intended for general aviation, which does not really have any other traffic-awareness other then radar/ATC. So again, this is meant to supplement that, not replace it. --Pilotboi / talk / contribs 21:42, 26 August 2007 (UTC)
replies: text: this is untrue. The FAA has mentioned several times that they see a day when ADS-B will replace radar.  — Preceding unsigned comment added by 134.134.137.71 (talk) 03:03, 6 November 2015 (UTC)

text: If you read any news articles about this they all speak of antiquated technology that is constraining our current air traffic system They all say that ADS-B technology will fix everything.  Just search google news for NextGen.  NextGen is being billed as a fix all when, like we both said, should only be used as a supplement.Andercee 21:21, 27 August 2007 (UTC)

text: Why would every aircraft need it?  You can currently take off and fly without a radio or transmponder.  Those that do swivel their head and look outside.  More and more of the country is making it harder to fly near large airports without a transponder.  They could very easily mandate ADS-B to all aircraft wanting to use this airspace.  I believe the FAA is developing a system where aircraft are under human control during take-off and landing at large airports, but transition to "Free-Flight" outside of these areas.  Even while under human control (text messages no doubt) the pilots can use ADS-B to sequence their arrivals.  You see this a lot at the really large airports, where pilots use ADS-B and TCAS to position themselves on approach or departure.  It makes flying easier.  If you've ever had to S-Turn a 747 on landing behind a prop-job, you'll know how valuable the extra information is.  —Preceding unsigned comment added by 68.241.142.161 (talk) 19:24, 6 January 2008 (UTC)
replies: text: The long-term perspective is indeed an ADS-B mandate for aircraft in controlled airspace. ADS-B is just a cheaper and better replacement for secondary radar. Just like TCAS, Mark-X and Mode-S are now mandated in certain airspaces, so will ADS-B be. And ADS-B is a fairly cheap technology - Australia seems to be able to implement it nationwide for about AUS$ 5000 per airframe. Compared to the cost of even a single secondary radar, this is very cheap. --Stephan Schulz (talk) 23:32, 6 January 2008 (UTC)

text: The short answer is that ADS-B can, and should be installed on everything moving in air eventually, and then perhaps on things that don't move (towers, etc). You are correct, ADS-B is never going to be that reliable until every aircraft is equipped. The FAA has done wonders to make sure that ADS-B remains overpriced, first by setting up the system on two different frequencies, one for airliners, another for everyone else. Second by requiring that all ADS-B out implementations be permanently installed and TSOed. The first is so unbelievably stupid I hope it is self evident (if not, go have a look at the Cerritos, California accident). Fortunately the avionics manufacturers are capable of overcoming the roadblocks that the FAA put in the way, and are producing dual frequency capable units at lower and lower prices.  — Preceding unsigned comment added by 134.134.137.71 (talk) 03:11, 6 November 2015 (UTC)
thread_title: How

message: I am conflicted about whether or not to include the following link: ads-bforga.blogspot.com. I read the guidelines about external links and figured I'd solicit some feedback from other users -- I am involved with that research but I am not the only contributor. It's a blog keeping track of work related to General Aviation; GA is currently one of the more worry-some stackeholders from the FAA's perspective due the possibility of user push back. Because of that I fee like it would be important to include at least a link to that topic. Nodapic (talk) 20:28, 4 June 2010 (UTC)
thread_title: ADS-B and General Aviation

message: It was claimed in the article that "VDL Mode 4 systems required by airlines in Europe as a mean for more efficient ATC service", giving  as a source. The source does not mention VDL Mode 4 in any way. It relates to ADS-B in general. In fact, it relates to the Eurocontrol CASCADE program, which prefers 1090ES. I removed the claim until someone can provide a source. --Muhandes (talk) 07:17, 27 June 2010 (UTC)
replies: text: VDL Mode 4 is in use in Sweden (and may be required there for certain classes of aircraft), but there is no Europe-wide mandate for VDL-4. The SPI/IR will require aircraft to provide ADS-B via 1090 Mode-S signals, starting 2015. But even that is in draft status, as far as I know. --Stephan Schulz (talk) 07:53, 27 June 2010 (UTC)

message: I have replaced occurrences of this word with "equipment." In standard English, equipage is mainly a horse-and-buggy term, whereas in this article it is being used (improperly) as a synonym for "equipment." Remember, the FAA and other aviation authorities dictate air regulations, but they do not dictate English usage, and this rather obvious and distorted borrowing from modern French will lead educated readers only to confusion, since they will of course be thinking of the correct definition of the word. Leave the jargon (especially the jargon that conflicts with standard usage) to the bureaucrats. There were only three or four occurrences in the word, probably in texts lifted from other documents.

message: This article fails to mention the international aspects of ADS-B.  Whilst the USA is adopting NextGen, Europe is also pushing ADS-B forward through the SESAR (Single European Sky ATM Research) programme.  Technically they're very similar, but ADS-B is not, as the article is written, an FAA or USA only technology!  — Preceding unsigned comment added by 213.107.92.144 (talk) 19:30, 24 September 2011 (UTC)
thread_title:  International Adoption 

message: The page is currently extremely difficult to follow and there is some very basic information missing. Some parts seem unnecessarily technical, and other parts appear to be extracts from an instruction manual (eg "You will also need to add a certified GPS" - why exactly would the reader of an encyclopaedia article need to do that?)
I am a technical reader (PhD in solid state physics and I work with about 10,000 pages of legislation for a living) but I could not make head nor tail of this article.
My questions are:
What is it? I can see that it's a technology for monitoring aircraft location and velocity, but how? Is there a central infrastructure? Can I buy an ADS-B receiver and stand outside my house and download the whereabouts of all aircraft within reception range? Presumably someone does that and collects the data centrally, but who, and how centrally? Do ADS-B compatible systems network together to convey this information globally, by peer-to-peer networking? I can see that aircraft are responsible for determining their own locations and then broadcasting that information, but it's unclear where it goes from there.
If ADS-B is a service, per the second paragraph, who provides the service? Are there competing providers and are they interoperable? Or is it merely a technology, per the first paragraph?
What is the ADS-B system mentioned in the second paragraph? Is there some commercial, national or supranational body administering it? The article mentions that the FAA will "pay for administering and broadcasting all the services related to the technology". Is this correct? Why would the FAA pay for a system which is used globally?
As you can see, despite a very long (too long?) and detailed article, an interested reader is left with essentially no idea of what ADS-B actually is. I'm sorry if this sounds very critical, and it's clear a lot of people who know a lot must have devoted a lot of time to this article, but for someone who doesn't already know a lot about it, it seems to assume way too much knowledge.  — Preceding unsigned comment added by Arcman (talk • contribs) 18:16, 18 February 2012 (UTC)

message: How does this work with military flights.  I am speaking of non combat type or routine US flights.  I understand the need for operational security, but if military flights are hidden then some degree of safety is compromised. Markbeckstrom (talk) 13:12, 27 July 2019 (UTC)
replies: text: It looks like routine military flights use ADS-B, as the tracking sites on the Web will show you.  I would imagine that in a shooting war situation, civil aircraft wouldn't be operating in the same area anyway, or collision with a military flight would be the least of their safety concerns. --Wtshymanski (talk) 05:14, 3 August 2019 (UTC)
replies: text: You correctly surmised is has to do with operational security.  Denying any and all potential adversaries information they may use to their advantage is a critical element of operational security.  As for safety, military flights remain in contact with ATC at all times while in the U.S. and international airspace while engaged in peacetime and training operations.  The only exceptions involve training in military use airspace, such as restricted areas and MOAs.  Even then, they usually monitor Guard (212.5/243.0).Clepsydrae (talk) 18:47, 18 November 2021 (UTC)

Outside USA, the UAT is rather non existant and 1090 ES is worldwide recognized standard.
