Noumea to Wallis island in the South Pacific. The Wallesians are big people like the Tongans and Samoans. Years ago the captain of a 737 was so concerned at the poor cruise performance of his aircraft he suspected a zero fuel weight error. Arrangements were made by radio that all passengers would be weighed on leaving the aircraft at Wallis is. Of the some 100 passengers aboard, the majority of adults were found to weigh over 100 kgs each with a good proportion being over 120 kgs as well as a few at 135 kgs.
The aircraft was subsequently found to be 1500 kgs over the max structural limit because the load sheet was based upon 77 kgs for males and 67 kgs for females. An engine failure on take off would certainly had led to a below expected climb gradient which was a problem at Noumea because of high terrain in the take off flight path.
