On every modern transport category aircraft flying today, there is a yaw damping system fitted to take care of unwanted yaw axis excursions. There is no need to touch the rudder in the cruise, climb or pre-landing descent phases, turbulence or not. Unusual attitude recovery or engine out are both different stories, but we have covered that already.
I would like to remind you, using the rudder is an instinct for many pilots, and use of rudder in turbulence happens even if it isn't recommended.
From what sources might we be able to substantiate such a statement?
