Yes, the Captain should definately be in command and the Line Checker merely an observer until the debrief.
However....
unless/until the TC decides you are 'not fit' and removes you from that post.
....this reminded me of a scenario I witnessed many years ago. The Captain was on a line check, 2 sectors, out and back; the Line Checker was on the jump-seat.
At the debrief on return to base, the Line Checker proceeded to fail the Captain, citing something the Captain had done on the outbound leg as the reason for failing him. The Captain immediately retorted that as the misdemeanor had occured on the outbound leg, the Line Checker should have failed him on the turn-round and operated the return leg himself. He claimed the Line Checker had therefore allowed the return leg to operate illegally!
At this point I left them to it before I got dragged into the ensuing fray. I should add that this happened long before CRM had been dreamt up; although it wouldn't have helped these two even if it had. Fortunately they are both long retired/dead, whatever. They deserved each other!
jordan2008, did "taking him to one side during the turn around" have any effect? It's amazing (though why should I be surprised) that some of these unsuitable characters still get into training/checking these days.
