That’s up from 24% — or just 3,707 aircraft — in October 2016 when the report began.
The FlightAware report also includes a current breakdown of equipage by aircraft type. For instance, it shows that 100% of the new Cirrus Vision Jet aircraft are ADS-B equipped, while older models like the Cessna Mustang show only 65% are equipped and the Cessna Caravan at 68%.
