  It's required in class A, B, C, and E above 10,000' MSL. And within 30 nm of a Class B airport (mode C veil). That leaves a ton of controlled airspace in which it's not required. There are more class D airports and airports with class E surface areas, than there are class B and C airports.

  > This is a bad take. It’s required in all controlled airspace. That is incorrect. ADS-B out is required in class A, in and above classes B and C of controlled airspace, in the class B mode-C veils and class E controlled airspace that over both 10K MSL and 2.5K AGL. It is not required in class D controlled airspace nor in the overwhelming majority of class E controlled airspace which isn’t covered by the prior paragraph. * - https://www.aopa.org/go-fly/aircraft-and-ownership/ads-b/where-is-ads-b-out-required https://www.aopa.org/go-fly/aircraft-and-ownership/ads-b/whe... ** - https://www.law.cornell.edu/cfr/text/14/91.225 https://www.law.cornell.edu/cfr/text/14/91.225
