Could have been either. If autopilot and autothrust are engaged and the FMC is properly set up, a TOGA command will cause it to fly the escape/go-around procedure automatically. If the approach is manual the pilots can either do it off their own back or follow the FD.
In the case discussed .. it was not one .. or other
It was an approach mode "hybrid"
Part controlled by automation ... and other (autothrust) controlled ?? manually ...
A mixture of genres that was dangerous in this case
So .. not recommended
And I emphasize again :
Is that the landing checklist was conducted by the PNF ??
The item autothrust is included in this list
If yes (I hope that AF pilots comply checklists!) the PF must know !
