My mistake. I thought he was talking about a senior FO's training to be captains. I read something somewhere else about international flying and make up of flight crews that must have confused me... probably from the start.

I'm aware of check airmen and IOE instructors.

I totally agree about every captain / PIC being a training captain. When I was a PIC in my last company I did everything I could to teach, train, and mentor the Pilots I flew with because that is what the more senior PIC's did for me when I was new.

If you adopt all the good/smart/safe things you see your CA's or FO's doing you'll wind up a top notch aviator, and the young kid sitting next to you will hopefully learn them too.

That being said, it is up to the PIC's of this world not to pass on bad habits or blur the standards with questionable short-cuts.
