B777
In a group environment the rules can be quite simple. There are many ways of skinning a cat. If a group decide to go about a particular task and it's not quite the way you would do it but the outcome will be safe, if, despite your input the group still wish to proceed down their original route then it saves a lot of stress and time, just to go along with it ,PROVIDING you believe it is
safe to do so. If however, you believe that the actions about to be followed could or would compromise the safe conduct of the flight then you must assert your position until you are heard and listened to. There are countless First Officers who have allowed the Captain to take them to the scene of the crash.
I think in the exercise you did the right thing, as you were tasked with an ideal outcome rather than one where if the solution were wrong you all (in the exercise) forfeit your lives (or at least a stack at 3pm on the last day instead of 5pm
)
