Problem
In this example, the First Officer notices that something is wrong with the engine instruments, but the Captain disregards the F/O's concerns and continues with the takeoff. In fact, the F/O addresses the issue of something "not being right" six times, with one of those six almost an acceptance of the problem. The captain, for whatever reason, justified those "things" as being "normal" and did not use any of the conflicting information offered by the F/O.
i. What do you think the F/O should have done?
ii. Would a more assertive F/O have prevented this catastrophe?
iii. Was the F/O's fear of job repercussions a factor in not speaking up to a superior (and highly experienced) Captain?
iv. Would the captain have even performed an abort procedure if the F/O were more assertive?
