I think its Controls Augmentation System (Maybe I'm confused with SAS)
But your issues with the AKG are simple, if you pull up with your stick, it should be fine, the moment you pull your stick, and use ailerons, that's not right, and you will break the pylons.
And it's the same with the Center fuel tank, you can use AG/1 without problem, but don't combine full pull up and roll at the same time, or you will broke it!!
Also, referring to your last post, the F18/16 are better for having FBW on 3-axis FBW? Not for me atleast, I experience a quicker reaction with the CAS than with the FBW, so I will prefer the JF-17 in terms of control surfaces than others.
