As Genghis observes, stick force/g is not directly tied to long stab certification concerns. Perhaps I should have been a little more expansive in my earlier post.
However, it is important to note that the factors which affect long stab likewise affect stick force/g .. the concern for the pilot being that, as well as having stick force problems, per se, the increasing manoeuvre capability might well see an inadvertent overstess in the pitching plane .. even a structural failure. Genghis' boffin colleagues are a point to observe ..
