Last weekend I decided to cross check ADS-B traffic reports between two different displays and saw some surprising differences.
First of all, this is what I?m running:
-ADS-B In/Out: Echo UAT + SkyFYX GPS
-Transponder: Garmin GTX-327
-Display #1: iFly 740b Moving Map GPS
-Display #2: Apple iPad Mini 4 running FlyQ
Regarding relative traffic altitudes, the displays were not agreeing with each other by about 300 feet. I found this to be a pretty consistent delta. That?s a huge difference! They are both getting their information from the Echo UAT so I?m thinking the issue lies within either the iFly 740b software or FlyQ and not with the Echo UAT. I didn?t get enough data to figure out which one was lying to me but I?ll have to figure that out on a future flight.
Any thoughts?
