Having flown both the Pacific and the Atlantic for over 20 years on the 747 Classic and the -400, the plotting exercise was the same in both aircraft. Granted the 400 is much more reliable than the classic with Delcos and Litton 92s, throw in GPS updating and any major system failure is fairly remote. However, if anyone has my luck, the first time it's not done is the time you will really need it.
Have flown for three different carriers, and all of them the SOPs were all the same. Plotting was mandatory.
