Basically FBW only allows FMGS or side stick ordered changes to flight path. Anything coming out of thrust/weight couple as in GA or atmospheric disturbances it will resist. That adds to the stability. But once displaced you need to bring it back. Here comes the difference in handling, AB FBW is flown with intermittent inputs because each time the SS is out of neutral you command the computer to do something. So give an appropriate input and back to neutral and again what is required and back. Otherwise you may set up PIO.
