Have to agreee with you there, although c would cause some torsional twisting due to pressure differential on the wing surfaces its not nearly as high as the sweep.
So in the eyes of the CAA, i think Alex you pointed this out to me once, whats the most appropriate.
If i remember correctly though this is most marked at lower speeds.?
If its wrong shoot me, its been 18 months since i did mine, if the plane aint stalling its still flying, besides im not getting much sweep on the PA44
