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.
Newer aircraft, including the Cirrus Vision Jet and the Honda Aircraft HondaJet, lead the equipage rates at 98 percent and 96 percent, respectively. But they share similar rates with some older models such as the Gulfstream G150 (96 percent) and Mitsubishi MU-2 (94 percent). In all, 11 business aircraft models were at 90 percent equipage or greater at the end of July, FlightAware data shows.
At the other end of the spectrum, though, a handful of models—all older, out-of-production aircraft—have an equipage rate below 60 percent, including the Learjet 55, which has the lowest rate at 42 percent. Other such models are the Gulfstream GIII (57 percent); IAI Astra (57 percent); Dassault Falcon 20 (56 percent); and Cessna Citation III (55 percent).
