@ChristiaanJ:

Let's not confuse the issue.

IMO a non A. FBW and even the FBW insiders are already confused.

Sometimes a simplified approach can explain a lot i.s.o. confuse.

I know there are potmeters involved (hey, did post the SS diagram myself)

BTW, the graph is from A330 FCTM...surely not intended to confuse the Flight Crew.

The related text:

As the flight mode is always aiming to achieve the selected flight path, avoid the

temptation to over-control. The recommended method to avoid over-controlling is
to make a small sidestick input, hold for a short period and then return the

sidestick to neutral. Even in turbulent conditions, the control law resists the

disturbances well without pilot inputs. The pilot should try to limit his control

inputs to that necessary to correct the flight path trajectory and leave the task of
countering air disturbances to the flight control system. If the pilot senses an
over-control, the sidestick should be released.
In climb, cruise, descent and approach, all these basic rules remain in effect.

How much time was the SS released to give the flight control system the
opportunity to stabilize the upset?
