To me, turbulence is mostly about pitch and roll, not so much about yaw. For sure, on those occations when I have been hand flying in turbulence, the use of rudder has never been needed. Then again, I've never been in severe turbulence.
Exactly.....there's no need to apply any rudder. You basically hang on. I've been in extreme turbulence (that's right...more than 'severe'). However, it was in a DC-6. I was flying and all I could do was just try and keep it more or less straight, but level was the most important part. Didn't really care which direction it went. However, I do not think a jet transport of today's manufacture would have survived that encounter.
