For those who are unaware the documentation for the original 747-400 QOTS for FS9 and FSX contained a section for cruise planning. This section contained various cruising altitudes from FL30 (30,000 ft) to FL41 (41,000 ft) and their optimal and maximum aircraft weights in both pounds and kilograms. My question is does the 777 documentation contain something similar? I did a quick search through the documents and found nothing.

Look first in the first volume of the FCOM table of contents, find that section PI is for inflight performance.  Then go to PI table of contents and find PI.41.1 41.7 deal with all engine long range cruise.  Easiest way is to use the FMS.

And don't forget the extra 0 on those FL's. ;)
