The A340 has a low cantilever wing; the A340-200/300 wing is virtually identical to that of the A330, with both engine pylons used while only the inboard one is used on the A330. The two engines for each wing provide a more distributed weight; and a more outboard engine weight for a lower wing root bending moment at equal , allowing a higher wing limited MTOW for more range. The wings were designed and manufactured by BAe, which developed a long slender wing with a high aspect ratio for a higher aerodynamic efficiency.
