RE: The A380 Wings Are Notoriously Bent, Any Idea Why?

It's called parabolic dihedral. It's a shaping of the wings that adds stability to the aircraft in flight and distributes bending loads more evenly. Airbus has used it in other wings as well. Airbus designed more of it into the A380 wing because of the higher loads it will have to take . -widebodyph...
