Stratus ES was built without GPS in order to provide affordable ADS-B Out to aircraft owners who have already invested in WAAS GPS. Stratus ES will make an aircraft rule-compliant when paired with any of the following navigators:

  • Garmin 480, 430W, 530W, 650, 750
  • Avidyne IFD440, IFD540

Stratus ES is a TSO certified* transponder that provides 2020 compliance in one box. 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.

Stratus ES is a form-factor replacement for existing transponders, such as the popular KT 76A/C, so installation is more time-efficient compared to remote boxes that need to be integrated with your old transponder. The Stratus ES can reuse an existing transponder antenna. It also accepts both serial and parallel (e.g. Gray code) inputs, so you can reuse most altitude encoders.
