I agree that it would not be possible to have the required knowledge of the OMA expected of our upgrading F/O's at the start of their Command training but I do believe they should be able to pass a standard upgrade interview before being cleared to line by the end of their training, if we are to have the same yardstick of competency.
There were some, and I know it's not fair to tar all with the same brush, that relied on their F/O's to provide them with the knowledge of proceedures and route knowledge to get through the flight without incident. I think this is where a large chunk of the greivances have occurred in the past.
