As such an experienced pilot, flying your 1900, I feel remorse that I need to point out that from what I read, there was really no reason to do a seat swap in flight--the point being that even with the autopilot on, there was no one at the controls. The FO/IOE Capt ck airman can make his own choices in an emergency situation, but I was curious why, if the Capt upgrade was dead, would you not land, do the seat swap, and taxi to the gate? If the Capt upgrade's life was still in question, why would you take time for a seat swap instead of concentrating on the divert? I have full confidence that these questions are easily answered by what the Ck airman's plan was, that is why I am asking. Emergency decisions are just that...there really is no right answer. Sounds like the ck airman did a great job. I am not second guessing his succesful outcome. I am curious professionally what his thought process was. The day I need sarcasm from a 1900 pilot for a reasonable question on a majors public forum has not arrived yet.
