Q: How big is the tablet display you include with the kit (the one pictured)?

The tablet is not included. That image is for reference to show that the Stratus 3i can be paired to display data on a tablet.

Q: Hello, Just wanted to inform everyone that the new Stratus 3 and 3i ADS-B receivers now support FlyQ EFB iPad/iPhone app. Out-of-the-box its locked into one app, Foreflight, but can easily configured to support FlyQ EFB. See the Stratus 3 or 3i documentation/manual for details. Hope this helps!

Thank you for providing this feedback. We will post it for others to reference.

Q: Does this transponder system Appareo Stratus ES come with an altitude encoder?

No, this does not come with an altitude encoder.
