In that case why did the first officer make this mistake, if you had briefed the go-around procedure????? Maybe too short a brief.
Day two of the sim session, the instructor had reviewed the two-engine inop details during the brief prior to going into the box....and in any case, the go-around procedure is reviewed and called out by the Flight Engineer directly from the QRH, as part of the checklist.
In short, the F/O, who was quite junior, had no excuse whatsoever.
It simply is a matter of RTFB.
