We are having an issue with our Skyview system. It registers 10 to 20 knots faster than our backup/original analog airspeed indicator. It appears that the analog is correct. In addition the altitude indicates 100 feet higher than the analog. We have replaced the AHRS unit and this made no change. Changed the pitot source no change. Any thoughts on what might be causing this discrepancy?
Skyview airspeed incorrect. Thoughts?

I love flying!
Are they both connected to the same static source? Have you done leak checks for both the pitot and static systems?
Pitot can't impact altitude.
Pitot can't impact altitude.
Not to brag (well, maybe a bit), but the IAS and altitude calibrations no our ADAHRS are rarely off. If you've replaced the ADAHRS, you've proven it. It's either the other instruments or the plumbing going to the ADAHRS.
Hi all thanks for the replies. I have been traveling so could not reply sooner. I did not think it is the ADAHRS unit.
We did have it switched from one pitot source (Aoa) to the tecnam pitot with no change. As we did not install this system ourselves what should I have our mechanic check/change? I suspect that it is something to do with the tubing leading from the pitot to the ADAHRS installed with the skyview. Is it just easier to replace this whole tubing system?
Again thanks for your help.

I have had to re-calibrate the ASI in the skyview setup (Zero Pressure Airspeed Calibration) after each update..
