Bealzebub said it all or almost all - what a post !
I expect my F/Os to assume the role of deputy commander at all times, and to be respected as such. My own respect for a F/O is in direct proportion to the degree to which he or she accepts their role as deputy, situation and circumstance may propel him / her into the command role without notice.
I expect that my F/Os will be better captains than I am. If they are not, then I have failed to pass on the accumulated wisdom of my captains, plus a little of my own, to be added to the potential talent within each F/O.
