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.


Excellent product and install kit. Works well.
