FlightAware Tracking ADS-B Out Compliance
FlightAware's ADS-B network shows that ADS-B Out compliance rates are climbing in the U.S.

As of last month, 11,455, or 68 percent, of the 17,031 in-service turbine aircraft registered in the U.S. were ADS-B Out-compliant, according to flight-tracking and planning service provider FlightAware's new monthly report on ADS-B Out compliance levels. That's up sharply from October 2016, when just 24 percent, or 3,707 of the 15,557 aircraft in the U.S. turbine fleet, were compliant. The U.S. ADS-B Out deadline is after Dec. 31, 2019 and applies to any aircraft that will fly in ADS-B airspace, basically where transponders currently are required.
