Many aspects of the (excellent) Airbus FBW family are poorly understood or not understood at all. Examples include how to use the sidestick and Fly-by-wire combination, another is G/S mini.
...............what can I do about it?..........causes problems.........enormously high approach speed**........There are 2 ways to overcome this............or the more common method is to immediately select a speed (say 160kts) and wait for the gust to die down. As soon as it has done so, you manage the speed again
The parts I have highlighted in bold worry me - especially from a training captain ?!? Selecting and pulling speed while flying a turbulent approach, when hands should be on the primary controls is distracting, unnecessary and not a good plan. It will also leave an Airbus in a poor energy state.
One does not need to ‘overcome’ or otherwise ‘fix’ G/S mini. It is there to keep us safe: one simply lets it and the A/THR do their job !
** Look at your groundspeed.
