Pattern Altitude
I have a GTN750 with a GDL88 for ADS-B in. I also have a FlightStream 210 and ForeFlight (latest version). Today on a flight, traffic was reported on my GTN750 at +18 (1800' above) but the same traffic on the iPad was reported at +15 (1500' above).
I have never seen this. There was no other traffic to compare (rural Nevada), but on the way back there was some traffic and the GTN and FF agreed.
Any idea how FF could report a different altitude since it should be receiving the same data as the GTN? Cellular was turned off so the traffic should not have been from ForeFlight's rendition of FlightAware-stlye traffic.
