The U.S. business turbine fleet has topped the 80 percent mark for ADS-B equipage, with the number of compliant aircraft reaching 14,684 as of September, according to flight-data tracker FlightAware. In its latest update for ADS-B equipage, FlightAware reported that 3,041 U.S.-registered turbine aircraft, or 17 percent of that fleet, are not yet compliant with the Jan. 1, 2020 ADS-B Out mandate.
The Cirrus SF50 Vision Jet has the highest rate of compliance, surpassing 99 percent, with only one of 133 aircraft left to meet the mandate. This is followed by the Mitsubishi MU-2 and Honda Aircraft HondaJet, each of which has a 94 percent compliance rate. Other business aircraft models reported as above the 90 percent market include the Cessna Citation CJ3 and CJ4, Bombardier Global Express, Embraer Legacy 600/650, Beechcraft Super King Air 300 and F90, Dassault Falcon 7X, Gulfstream G150, IAI Galaxy, and Piper Cheyenne.
Not surprising, the lowest compliance rates are found among older, out-of-production models. The Gulfstream III had the lowest, with 55 percent compliant of the 38 still on the U.S. registry. This was followed by the Bombardier Learjet 55, with a 60 percent compliance rate, and the Citation III, which had a 61 percent compliance rate. Other fleets that had a compliance rate below 70 percent were the IAI Westwind and Astra, Learjet 35, and Falcon 20.
