Skyview compass calibration

[litobrit]

Hello,
Some troubles to calibrate.
My Skyview is working fine in a VL3 ulm (145kts). The retractable landing gear moves the gears and brakes very close of the compass sensor located just behind the seats, so the ground calibration is not the same than in flight. 
There is no way to calibrate in flight, only a way to improve ground calibration between the 4 cardinals headings by making turns.
Why not create a in flight calibration for no wind days?
In that case, the heading is the ground track and  GPS ground speed is true air speed.
So, after making a few turns the Skyview computer should be able to give a very accurate in flight calibration.

There IS an in-flight magnetometer calibration procedure - see Page 5-10 of the SkyView System Installation Guide.

However, it may not work given that the magnetic environment is radically different from the ground calibration and the in-flight calibration. Your installation isn't compliant with our recommendations that there be no magnetic interference in the area where the ADAHRS or the (optional) SV-MAG-236 remote magnetometer is installed. The magnetometer calibration procedure(s) are designed to compensate for MINOR variations in the magnetic environment in the area of the magnetometer. What you're describing is a major variation in the magnetic environment in the area of the magnetometer, so it's quite likely that you'll never be able to get an accurate compass heading with the SV-ADAHRS-200/201 installed in the current location.

Thus, we recommend that you install an SV-MAG-236 in an area where there is no magnetic interference. That will result in an accurate compass heading.
