Newcatle's runway is shorter than Durban and Emirates Operates out of there. Just did the sums, An A330 can do a 220000kg's take off out of Durban at a temp of 35C. Max is 230000kg's. Max zfw is 170000kg's plus 48000kg's of fuel gives u 218000kg's. So no probs for the A330 to operate out of Durban with a full load.
