With or Without WAAS GPS

Stratus ESG

Stratus ESG was designed with non-glass panel aircraft in mind. Our simplified solution includes a 1090 ES transponder and certified WAAS GPS in the same box. It’s truly an all-in-one box solution for 2020 compliance.

Stratus ES

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, 6XX, 7XX
  • Avidyne IFD440, IFD540

Add ADS-B In

Both Stratus transponders are available in a kit that includes an ADS-B In receiver (Stratus 3i). Stratus 3i was designed to stay plugged into the transponder and tucked behind the panel to benefit from external antenna signals and aircraft power.

If you already own a portable Stratus receiver, there’s an interface kit available to connect your receiver with the Stratus transponder.

5-Year Warranty

Appareo offers an industry-leading 5-year warranty on all certified Stratus transponders that are purchased by December 31, 2019. This offer also applies to previously-registered warranties on certified Stratus transponders.

Simple Installation

Designed with the common 1.65″ tall form factor, Stratus transponders easily replace your existing transponder. Here’s what to consider for install time:

  1. Replace old transponder in panel.
  2. Reuse existing transponder antenna.
  3. Reuse existing altitude encoder.
  4. (Stratus ES) – Connect to existing navigator.
  5. (Stratus ESG) – Install GPS antenna (included in kit).
