Narrative:
During the before take-off checklist the first officer discovered a large discrepancy with the load closeout. It was indicating 110 children aboard; with a passenger count of 138 and cargo weight of 6240 pounds. It took several radio calls to operations and considerable delay to rectify this error. After a couple of revisions we had what appeared to be a suitable load closeout revision; and the weight had now increased by approximately 10000 pounds. We went from a planned tps weight of 138500 pounds to 149000 pounds! With our original tps weight; with a thrust setting of 22K and a north departure with flaps 5 we both wondered what the outcome would have been if the mistake had not been identified by the first officer? Moral of this story: take a delay if needed to make sure everything is correct. They can get you into a rush...so slow down and make sure all your ducks are in a row before departing. Fly with a good first officer.

Narrative: DURING THE BEFORE TAKE-OFF CHKLIST THE FO DISCOVERED A LARGE DISCREPANCY WITH THE LOAD CLOSEOUT. IT WAS INDICATING 110 CHILDREN ABOARD; WITH A PAX COUNT OF 138 AND CARGO WEIGHT OF 6240 LBS. IT TOOK SEVERAL RADIO CALLS TO OPS AND CONSIDERABLE DELAY TO RECTIFY THIS ERROR.

WE WENT FROM A PLANNED TPS WEIGHT OF 138500 LBS TO 149000 LBS! WITH OUR ORIGINAL TPS WEIGHT; WITH A THRUST SETTING OF 22K AND A NORTH DEP WITH FLAPS 5 WE BOTH WONDERED WHAT THE OUTCOME WOULD HAVE BEEN IF THE MISTAKE HAD NOT BEEN IDENTIFIED BY THE FO? MORAL OF THIS STORY: TAKE A DELAY IF NEEDED TO MAKE SURE EVERYTHING IS CORRECT. THEY CAN GET YOU INTO A RUSH...SO SLOW DOWN AND MAKE SURE ALL YOUR DUCKS ARE IN A ROW BEFORE DEPARTING.
