It is so that the cargo is level, on the regular A330, the nose is at a downwards angle on the ground. In the cargo variant, it has to have a parallel fuselage with the taxiway so the cargo isn’t displaced.
Thank the lord there aren’t any crybabies complaining about the OP not sharing his camera. @anon79353067 I gotta say, you take such nice pictures, and I appreciate the dedication and time you take to sharing these with me and the people in this community. :)
I also have to say how incredible the bypass ratio of those engines are. Serious stuff GE manufactures. Great shot!
