Leeham Co: In Part 4 of the article series, we put together an assumed complete Chinese-Russian wide-body aircraft with fuselage, wing, engines, etc. It is now time to understand what kind of performance that can be expected, given the data we have from the wide-body partners, Russia's United Aircraft Corporation (UAC) and the Commercial Aircraft Corporation of China (COMAC).

We will combine these data with the ones we have deduced as plausible to fill the gaps, given the time frame and technology level that UAC and COMAC intend to use.

Out will come a first estimate of what kind of performance such an aircraft can have in terms of efficiency and payload versus range capability.


  • We can use all the data we have gathered to make a first estimate of the efficiency of the Russian-Chinese wide-body.
  • We also have enough information to do a first payload-range diagram and to compare that with the diagram for Boeing's 787-9.
