Following the PAP instructions, with the syringe attached to the pitot tube, the behavior I'm seeing is as if I reversed pitot and static lines on the ADAHRS box (I didn't): If I withdraw the plunger, the altitude displayed on the Skyview increases and the airspeed displayed increases. The altitude shouldn't be affected and the airspeed trend is backward. Could the ADAHRS box be plumbed backward?
