Indeed. Not everyone even has to have ADS-B Out. You only need it if you’re going into or over Class C or B airspace, in the Class B veils, Class E above 10,000

Indeed. Not everyone even has to have ADS-B Out. You only need it if you’re going into or over Class C or B airspace, in the Class B veils, Class E above 10,000 except below 2500 AGL, and in Class E over the Gulf of Mexico. That leaves huge swathes of airspace—dare I say most airspace in the US—where ADS-B isn’t required. You could fly across the entire country without hitting an ADS-B requirement. And the only way for ATC to see non-ADS-B aircraft is radar.

- danaliv 7y agoIt’s not just about seeing you, it’s about seeing everyone around you too. ATC’s job is to separate aircraft and they can’t do that if they can’t see non-ADS-B aircraft. In fact just today I overheard an approach controller vector an American Airlines jet around VFR traffic at 1700’. That VFR traffic was in “non-rule” airspace, where ADS-B isn’t required. (I saw the jet and the VFR traffic from my cockpit.) They won’t be able to do that without radar.
