What's the date of the IL-96, or 86 for that matter.
Il-86 first flight 1976, commercial service late in 1980.
Il-96 first flight 1988, entry into service 1993.
What about the A340-500 and -600? Why exclude the latest versions?
Il-96 wingspan 60,1 m, MTOW 270 t.
A340-300 wingspan 60,3 m, MTOW 276,5 t
A340-500 wingspan 63,5 m, MTOW 380 t.
Pretty obviously the A340 new generation with a bigger wing and far bigger MTOW comes to a different niche, and is not competing with Il-96. While A340-300 is.
