If I was the captain, I would probably have had lot of confidence in my buddy in the RH seat as he had more experience on the SA route, 39 rotations against my 16. But I think I would have liked to take a peek at the Wx before taking a nap. I would also have expected him to listen in to other traffic, especially those ahead of us, on 121.5 or whatever.
The third guy, had the least experience of all, and it was suggested that he moved into the LH seat when the captain left. Is that significant?
