By reacting to gusts like that, the auto-thrust is working as designed and keeping you safe. Why prevent it ?
From the Airbus A320 Family Instructor Support manual: UDY0102 Jan 2001:
In the case of a tailwind gust:
And, Hans; the whole point of GS Mini is to react to gusts and adjust the thrust to stay above a minimum energy, so it most certainly DOES adjust for gusts !! - that is its whole purpose.
Why disable this vital system just because you don't like the engines spooling up like that ? We cannot know the instantaneous wind*, so how do we know what is a safe speed/ energy/ thrust setting ?
* the three ADIRS do though
