The iFly software is always watching to see which Avaliable GPS signal is stronger, so in your case, when you see the ADS-B in the GPS box, yes, the iFly is using GPS data from the Echo over WiFi. If you were to disconnect the Echo, then the unit would resort back to using its own GPS (Or plugged in external GPS)
To clarify, I don't think iFly is actively comparing GPS sources to see which is "stronger". I think the iFly logic is built such that if you are connected to an ADSB device with its own GPS, then iFly will use that. If that source is not available, then if the device it's running on has built-in GPS, it will fall back to that.
I'm pretty sure that it's possible for the iFly device to have a great GPS lock, but the ADSB device to have a marginal GPS lock, and iFly will still continue to use the ADSB GPS.
