B757-200 First Officer requests additional training; believing that the Internet and other Computer Based Training received as the result of a merger is inadequate.

Narrative

I have done the training CBT's [computer based training]; studied the manuals provided in the chief pilot's office ; downloaded the aids from the Internet; practiced my flows; been chair flying; done everything I could - and I still don't feel comfortable that I can successfully implement all these new procedures; call outs and flows in the flight environment. I have always studied new aircraft type and new aircraft procedures the same way. I do everything I listed above - and then I practice in an FBS or a simulator with a trained instructor. Invariably; no matter how well I THINK I know my stuff going into it; there are things I didn't pick up on; or small ways I misinterpreted what was meant by a maneuver. Flying a new maneuver in the sim (or airplane) is often a lot different than you think it's going to be practicing from your chair in your home. I need these motor skills and procedures CEMENTED into my memory so I can be confident I can successfully execute them when I'm only at about 75% (if that) in the 13th hour of my crew duty day at the end of an all-nighter; flying into weather to a CAT III ... and oh yeah; what were those new Autoland callouts? What's the new go around procedure? I do not feel safe to get in a cockpit and be responsible for these and all the other new procedures without additional training. I have requested additional training; and hope to get it. The chief pilot's office told me they could not line it up before this flight in question. I flew the flight under the old procedures. The chief pilot's office told me if I did not feel safe; I should take myself off the flight the next day (today). I did that. I need additional training; and look forward to receiving it. I do not feel I can safely operate the aircraft without it.
