The new A340 does not appear to respond to turbulence, nor does it seem to generate any internally, likely due to its external flight model implementation. While developers such as A2A (for example, with the Comanche) also use external flight models, their aircraft still properly interpret and react to simulator-driven turbulence. To verify this, I conducted a controlled test using historical weather with severe turbulence conditions. I compared the A340 against aircraft from iniBuilds, PMDG, an
