It is the same in Airbus, but it is in my opinion not very well explained in Airbus literature.

The system is stable, which means that it tends to resist displacement, but it doesn't mean that it prevents it, and by no means will it make the airplane recover the initial parameters.

In the Airbii, the best you can do in gusty conditions is to let the airplane resist gusts, and after that you bring the airplane to the desired flight path and speed. If you try to counter the gusts at the same time as the FBW does, then the coupled inputs will be excessive and you will be continuously swinging.

gust-FBW-pilot input…..gust-FBW-Pilot input…gust-FBW-pilot input and so on, instead of gust-pilot input nonstop all the way to the threshold.

FCeng84, that is interesting, the fbw yaw. Does it have a protection? I mean, normally in gusts it is not a good idea to kick the rudder to keep the ball centered (AA A300 in NY) but it is recommended to let the fin do its job naturally.
