But AF culture had something to do with that, and other, incidents/accidents. They have had too many problems. It’s been written about by safety experts ( complacent ).
Letting an FO take the AP off, and disconnect the auto thrust in extreme weather they were facing was complacent. IIRC, the aircraft became slightly high as it approached the runway threshold.
AP on to minimums ( Airbus says 80 feet on Cat 1 ILS which is what they had ) , and keep the auto thrust on ( GS mini deals with wild winds ). Not a time to be hand flying and using manual thrust.
That decision ( I doubt the FO even briefed he would do that and no Captain should allow that given the weather, and go around possibility ) to take the AP and auto thrust should have been briefed ( when will disconnect AP and use of automation ) and discouraged if brought up.
Not to sound critical but that’s being complacent.
