This from AOPA's Aviation E-Brief: November ADS-B Equipage Rate Continues Modest Ascent by Jerry Siebenmark - December 10, 2019, 9:51 AM ADS-B equipage of U.S. business and general aviation turbine-powered aircraft rose modestly from a month ago and was up by double-digits from a year ago, according to FlightAware’s November 2019 ADS-B report released yesterday. Eighty-eight percent of business and general aviation turbine aircraft—15,520—were compliant with the FAA’s January 2020 mandate in November, a 3 percent increase from October and 24 percent higher than the 10,107 equipped aircraft reported last November. The aircraft types with the highest equipage rates in the period were the Cessna Citation Latitude and Embraer Legacy 450 twinjets, both at 100 percent; followed by the Cessna Citation CJ4 at 98 percent; and the Citation Sovereign, Dassault Falcon 7X, Gulfstream G650, and Honda HA-420 HondaJet, all at 97 percent. Leading aircraft with the lowest ADS-B equipage rates for the period was the Air Tractor AT-802, 42 percent, followed by the Quest Kodiak, 59 percent; Cessna Citation III, 67 percent; Learjet 55, 70 percent; and Dassault Falcon 20, 72 percent. The report said 2,099 U.S.-registered turbine aircraft remain unequipped.
