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 430W, 530W, 6XX, 7XX
  • Avidyne IFD440, IFD540

Add ADS-B In

Both transponders are available in a kit that includes an ADS-B In receiver (Stratus 3i), which was designed to stay plugged into the transponder (tucked behind the panel), benefiting 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, 2018. 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).
