When comparing the overall length of the aircraft with its wingspan, whereas in the past the length of the aircraft tended to be greater than its wingspan, today, in contrast, the wingspan can be equal to, or even exceed the fuselage length. For the A330neo, its wingspan is as wide as the fuselage is long – around 64m!
It should be noted that wingspan, for all intents and purposes, has now reached its practical limits on widebody aircraft due to the physical constraints of the airport gates where the aircraft are parked adjacent to other aircraft. If it wasn’t for this gate constraint, then the A330neo’s wing could in theory have been designed with even more span. Nevertheless the Airbus design team in Filton, UK, succeeded in achieving a very impressive aspect ratio, reaching a record value of almost 11! By comparison, most other modern airliners in production today have managed an aspect ratio of only around 9 or 10. So in this respect, the A330neo really is leading the field by a significant margin.
