Well that got technical right away. In general terms, would I be able to know about small aircraft with transponders, ie C172 etc, flying into the airport I fly? It's a class E airport, but near a class B airport so, most aircraft are transponder equipped. The device I am looking at is an ADS B - in, receiver, and I would send the information to my iPhone 6+ via wifi. It seems like most major areas now have ADS -B coverage and since I don't have to install an ADS-B out signal, yet. It seems like a solution to what I am looking for, which is some indication of another aircraft near me when my eyes did not pick him up.
Since I am not sending the "out" signal, would I not receive the transponder only traffic? Also since the "out" signal is not present, would the set up just report useless information to me and maybe even show my own glider as traffic?
The device I'm looking at is a TRX1000 from Air Avionics, used with iGlide software.
Thank you.
