Recently, I was on flightaware looking up a friend's GA plane. Stumbled into ADSB and feeding. I am techy and have a bunch of spare computers I could put to use for that. But then, being in central NJ, there's a bunch of feeders already set up (1 is less than a mile from me if their map is accurate. No sense doing this if it isn't for the greater good - I have enough things to keep me busy as it is. But if it helps / isn't redundant, I'm in. Then I stumbled on this site. What? I was thinking all this feeding is going into a big pot of info that everyone shares / the FAA needs / etc. No? There's a bunch of websites doing this? independent of other sites? so the map on this site might have more / less / different info than flightaware's? And other sites? Or everyone that who sends feeds sends to all the sites (how many are there?) And the tar1090 map here is just 1090?. there's also 978? Is there a different map here for that? (seems a most comprehensive map that uses all the data available would be the most useful? And the FAA uses radar so they don't need this data? if there was a crash or something then they might want this ads-b data and collect it from different websites? they aren't actively collecting the data on an ongoing basis? The home page here talks of this data being for hobbyists, journalists, etc. Not needed for ongoing safety of a flight? Sorry, if this is way too basic for you guys! Is there a page here that spells things out like this / how the 'industry' works?
