Appareo’s approved model list (AML) STC for the Stratus ADS-B Out transponder has been expanded to include twin-engine airplanes, starting with the Cessna 400-series, including the 425 (Corsair and Conquest I) turboprops.
The AML-STC now covers 219 aircraft, for installation of Appareo’s Stratus ES and ESG 1090-MHz transponders. The Stratus ES can pair with approved position sensors in Garmin and Avidyne navigators, while the ESG includes its own qualified GPS. Both are made to replace existing transponders without expensive panel modifications.
The Stratus ES/ESG can share an external antenna with most types of portable ADS-B receivers, including Appareo’s own Stratus series of receivers. The ES retails for $2,495 and the ESG for $2,995; both qualify for the recently reopened $500 FAA ADS-B rebate.
