ADS-B Fleet Grows, but 3,600 Bizcraft Still Unequipped
Learjet 55s comprise the least compliant fleet, with 42 percent equipped, while the Cirrus Vision Jet is most compliant with 98 percent equipage rate.

While 79 percent of the U.S. turbine business aircraft fleet was ADS-B Out compliant by the end of July, some 3,632 aircraft were still not properly equipped for the mandate approaching on January 1, flight-tracking specialist FlightAware said in its monthly update on equipage rates.

By the end of last month, 13,862 U.S. business aircraft were ADS-B compliant, according to FlightAware. This is up by more than 500 aircraft compared with the equipage at the end of June and by nearly 3,300 from the 10,597 compliant business aircraft at the end of 2018.
