So, I was just doing a leg between CYEG and CYVR, and noticed that above rocky mountains where theres turbulent air the turbulence seems to only affect the pitch axis which is swaying up and down like crazy and feels like its just balancing on the center of gravity rather than dynamically moving in the air, there seems to be little if any roll or lateral moment occurring in turbulent air, feels like the same behavior as the default a330 which also sways unnaturally only on the pitch axis. Is this really indented behavior or just a "limitation"?
