I was doing some work that required me to disconnect my AF5500, and when I reconnected it on my first flight the airspeed read 0. My backup EFIS (Dynon D6) read correctly for both altitude and airspeed. On the ground I checked the airspeed on the calibration menu and it is reading negative for some reason. I couldn't find any setting that would reverse it.

User error. Despite checking several times, I finally reversed the pitot and static lines and it was fine.
