Thanks for your PM Lyman.
I can't tell there was an issue with the attitude indicator(s) but it is a possibility there was one or they thought there was one as they choose to manipulate the ATT HDG switch or is it the way it is teached at airfrance to turn simultaneously both AIR DATA and ATT HDG switches ...
For sure there was confusion, big time, and those invisible sidesticks just contributed to that confusion.
