Paul –

 

I recently upgraded to Dynon Skyview and had to add the frequency converters. They are also available through Grand Rapids, part number CP-10A

 

I found the calibration to be a real headache. Both the Princeton converter and the SkyView have built-in calibration routines. I used a two-point (empty and full) linear calibration for the converters and then let the SkyView calibration routine to cope with the non-linearity due to fuel tank shape. The Dynon calibration routine wants you to add two gallons, mark the calibration point, then repeat. The problem is that the Princeton converter takes a full two minutes to average out a change in fuel level, so calibrating a single 33-gallon tank takes quite a while. To make matters worse, as the plane’s weight increases due to fuel load the strut compresses and the wing drops a couple of inches, throwing the whole calibration off. The solution might be to jack up the plane to both level it and prevent it from moving, and redo the whole process.

 

Has anyone had similar experience or come up with a better procedure?

 

Thanks,
