Please explain log_imu_accz graph

Hi all,

This afternoon I logged a short flight in heavy wind.
Just a little bit of hovering.

When looking at my log_imu_accz graph it appears that I have a lot of noise on the line, but most of it is on the upper side (less than 9.8 m/s2) side. What could be the explanation of this?

Best regards,

Jan Willem

Vibration at just the right frequencies. I would not expect altitude hold to work very well like that.
