I was scratching my head on the captain having his feet on the floor too. I thought all pilots monitored all flight controls when the other pilot was flying especially during critical phases of flight or when something unusual was happening.
I have talked to the pilot flying the A300 trying to land at MIA when he got continuing uncommanded rudder inputs forcing him to go around. He questioned whether they would be able to control it enough to get on the runway at all. No, I wouldn't fly an airbus 300 if I had any other choices no matter how good looking the FA's were or how well it paid.
