On SkyView, the filtering is actually tunable, and we document how to adjust it on our wiki page about sensor definitions. Unfortunately, the D180 isn't as flexible, and the sample rate is high enough to show fluctuations, but not high enough to always effectively filter (depends on the sensor and the application, ultimately). However, it's pretty rare that we get reports of this with the Kavlicos on a D10/D100 series.

Thank you for the clarification!
The information you added helps differentiate worrisome pressure value displays from normal behaviour. I wish Rotax would have done this too.

Something loosely related:
I had a firmware upgrade from the version approx July 2007 to the actual one from March 2018. Rotax CHT temperature now "appears to me" to change faster than before. But maybe I'm imagining things here.
Did Dynon change the averaging/filtering for the Rotax CHT input over these years? I didn't saw this in the release notes.

We fixed the volatile CHT (and cooler CHT in climb :O): It was the connector to the CHT probe.
