Would also like to know how well command decisions would go in the event of the left hand seater becoming incapacitated. There are many events of this nature per year.
I would think it wouldn't be too long before such an event would take place AND some sort of other emergency or something out of the ordinary would make things VERY challenging for an F/O with said qualifications.
Gaping hole in the swiss cheese I reckon...
