Ok, I'll try not to be the "arrogant American" pilot that you accused us of being in another thread and figure out what you were asking.

I think you confused shackone's concept of training to be a captain with logging 121 PIC time. There is a lot more to being PIC than the operation of the airplane that you learn in initial training. While you may be exposed to these concepts, generally they are not taught in detail to new FOs. How to function in the airline's system, how to flight plan for high altitude turbojet operations, how to quickly work the system to get an on-time departure with less than favorable situations, how to deal with being in command of a flight crew (most newbs have never dealt with an FA before). Those qualities and other tricks of the trade are what FOs need to practice before time comes to upgrade. It has nothing to do with logging PIC time. It has everything to do with passing upgrade, not getting fired, and not killing yourself, your crew, or your pax. After you pass the upgrade, you can worry about getting towards that 1000 turbine PIC.
