In airbus FBW pitch changes are achieved through the side stick as g demands. It is linear from 1g with stick neutral to 2.5g stick full back. As long as stick is out the elevator and stab move to give you the g and once achieved, through feed back mechanism maintain that position. When the stick is returned to neutral it is 1g demand and computer will move the elevator and stab to achieve that. Any g effect that is not ordered through the side stick either through thrust/weight or environmental the computer resists as it tries to maintain 1g within it's authority.
