The FAA is spot on, being within three years of mandatory retirement I have seen a gradual erosion of flying skills to usually based on company culture.
Thankfully I work for a company that encourages manual flying in appropriate situations but it would seem that the culture from previous companies hangs on and the First Officers can tell a Captains previous company from the way he flys.
By restrictions on the way first officers fly the aircraft and over reliance on automatics captains are eroding the skills of their FO’s and restricting the appropriate use of automation. Blind and unthinking following of SoP’s is also having the same effect SoP’s are a useful tool but they also have to be appropriately applied.
