Hi Hawk37
This will answer Neptunus as well. The A330 will go thru a rough ride if the FCPC's are lost due to failures and having a full trim tank. The Turbulence Damping or Alleviation function use the PRIMS to compute a turbulence damping command,which is added to the normal law command for the elevator and yaw damper. The alleviation system on the airbus addresses the Aeroelasticity problems of bending and twisting due to pilot inputs or atmospheric disturbances.
The way I see why we get a fuel benefit by having an aft CG. Aft loading= less downforce on the tailplane=less apparent weight the aircraft experiences=less lift required to keep the A/C flying at a constant AOA=less thrust required to maintain level flight...which amounts to fuel savings or an increase in range.
