Then how do you explain a rotation 20kts before V1if he is in the habit of scanning his PFD and engine instruments? How do you explain the startle factor in the sim when an RTO occurs and they should be scanning those very same instruments that procedure dictates should be scanned? According to your Utopian world of airline SOPs an F/O should be equally as familiar with OM1, FAM whatever as the Captain but because they are not ultimately responsible for the operation of the aircraft there is usually a knowledge gap. I'm not sure what seat you blokes occupy but if it is the LHS next time you are P/F have a glance at where your F/O is looking. Any Captain who is relying completely on the F/O to notify a failing engine is not doing the job properly. Any Captain who doesn't take over and conduct an RTO before the F/O notices any problems is not doing the job properly.
