That's changed since 2020, you have to be far away from controlled airspace to just broadcast Mode-S anymore.

- sokoloff 6y agoNot true. Most of the US is controlled airspace where you aren’t required to be ADS-B equipped. It’s a small minority of airspace under 10K MSL where it’s required (just class B veil and class C airspace and above class C rings). Most of class D and E airspace is not in the above category and therefore not ADS-B required while still being controlled airspace.
