The requirement to immediately use the QRH in preference to the ECAM procedure for the 'all-engine-out' scenario was the subject of an AIRBUS INDUSTRIE symposium held last year. Similar recommendations for 'smoke' procedures were made at the same time.
The reasons are complex, and are set out in a powerpoint presentation distributed by AI. Your company training department should be aware of this, and either copies made available, or a text precis setting out the salient points.
Because of the critical nature and seriousness of this event occurring without you guys apparently being aware of the correct procedure to follow, then I am prepared to send you a copy of the ppt if you email me.
