Last week, one friend of mine flew from MIA to CCS and got to visit the cockpit before the flight. As usual, he asked many things and had a great time looking at the controls, but he saw something kind of weird and not common: The First Officer was seating in the Captains seat (they switched places).
He thought it was only for briefing and check lists, but when the aircraft landed at CCS, he went back up to the cockpit and they were still like that.
So, my question is: Is there any rule related to this situation...Captain seating in the F/O side and viceverse?
Just for curiosity!
Thanks in advance!
