Narrative:

On aug/fri/00 at approximately AM00Z we were operating from phl-atl. We were at a weight that if we would have departed, we would have arrived at atl at 10000 pounds overweight for landing. This would have left us to either dumping fuel or holding to burn down to landing weight. After we commenced our taxi to the inactive runway, I recomputed our weight and balance and found a math error that I had made. We returned to the ramp and defueled so as to land at the proper weight. Factors in this incident were my mathematics and desire to hurry and depart on time. Contributing factors to this were load planning and dispatch giving us a weight and balance that was not correct.

Title: A DC8-71 IS TAXIED BACK TO THE RAMP WHEN A RECOMPUTATION DISCOVERS AN OVERWT CONDITION EXISTED FOR LNDG AT ATL DURING THE GND OP AT PHL, PA.

Narrative: ON AUG/FRI/00 AT APPROX AM00Z WE WERE OPERATING FROM PHL-ATL. WE WERE AT A WT THAT IF WE WOULD HAVE DEPARTED, WE WOULD HAVE ARRIVED AT ATL AT 10000 LBS OVERWT FOR LNDG. THIS WOULD HAVE LEFT US TO EITHER DUMPING FUEL OR HOLDING TO BURN DOWN TO LNDG WT. AFTER WE COMMENCED OUR TAXI TO THE INACTIVE RWY, I RECOMPUTED OUR WT AND BAL AND FOUND A MATH ERROR THAT I HAD MADE. WE RETURNED TO THE RAMP AND DEFUELED SO AS TO LAND AT THE PROPER WT. FACTORS IN THIS INCIDENT WERE MY MATHEMATICS AND DESIRE TO HURRY AND DEPART ON TIME. CONTRIBUTING FACTORS TO THIS WERE LOAD PLANNING AND DISPATCH GIVING US A WT AND BAL THAT WAS NOT CORRECT.
