F/O as an asset to the captain.
AS A CAPTAIN , I FEEL FIRST OFFICERS ARE AN ASSET TO ME, and that's what the manufacturer thinks, when he allots specific roles for a PF AND PNF , neither of them is complete without each other, its just my more experience as a captain , that I am more aware and have in the past dealt with the situation before, and my decision making process helps me with that, F/O is equally capable, he has a type rating, he clears his checks every 6 months, he flies with other captain ( good and bad) and is more situationally aware....thats what my feeling is.
