During the approach checks what did the landing pilot brief the other pilot that his actions would be in the event of a malfunction before committal point? My guess is somethiing like -
'In the event of a malfunction before I call committed we will go around to the left/right and climb to MSA. Start the stop watch, call Nr, height and airspeed, no shutting down of an engine below 500' unless there is a fire.'
That is what the other pilot will be expecting and if If I were the sim instructor I would be expecting the go around too.
