The Stratus ES is a 1090 MHz extended squitter (ES) transponder. Designed with the common 1.65″ tall form factor, it’s an easy replacement for your existing transponder. Stratus ES is a solid state transmitter that provides 310 watts nominal power output. Its modern keypad makes entering a squawk code easy. The convenient VFR button minimizes pilot keystrokes.

Want to install Stratus ES/ESG, but don’t see your airplane on our STC list?Not to worry! Even while Appareo is building their STC AML, you’ll have no trouble getting Stratus ES/ESG installed in your Part 23 aircraft, based on their lead STC.
The FAA created a policy to make it simple to use the lead STC to install ADS-B Out equipment on additional Part 23 air frames. (Part 23 includes most general aviation aircraft). This policy was designed to keep ADS-B installs moving smoothly and make things easier for your installer.
I am very happy with my stratus transponder it works great . I wired it myself and received the faa $500 rebate. I have had no problems being seen by atc in my various travels in my exsperimental Cozy IV. I really enjoy being adsb compliant.
