Agree that the performance will be different for two aircraft types just showing a comparison and anyway the A310 was derived from the A300 unlike your B737-B757 comparison and just for accuracy Max T/O weight for A300B4 is 363,000 not 336,000 as typo earlier so I suspect with the weight reductions as reported for the A310 the operation will be possible, one would have expected Shaheen to have done their homework.
