THE FO ASKED THE CAPT IF HE THOUGHT THEY SHOULD INFORM THE TWR THAT A FEW MINS IS NEEDED TO RECEIVE THE WT AND BAL DATA AND COMPLETE THE CHKLIST. THE CAPT SAID NO AND REVIEWED THE SUBSEQUENTLY ACQUIRED TKOF PERFORMANCE SETTINGS ASSUMING THEY WERE BASED ON WT AND BAL RECEIVED. THE CAPT; AFTER TKOF; LEARNED THEY DID NOT HAVE THE REQUIRED WT AND BAL ON BOARD.

Narrative

ON DEP FROM DFW WE WERE HAVING SOME DIFFICULTY WITH DATA LINK RECEPTION AND HAD TO MANUALLY LOAD THE FMS AT THE GATE; AND DURING TAXI THE FO ATTEMPTED TO OBTAIN THE LOAD CLOSEOUT VIA ACARS A COUPLE OF TIMES WHILE WE WERE ACCOMPLISHING THE BEFORE TKOF CHKLIST. AS WE APCHED THE DEP END OF THE RWY; HE ASKED IF HE SHOULD INFORM THE TWR THAT WE WOULD NEED A FEW MINS AND I TOLD HIM TO HOLD ON; AS I THOUGHT THAT WE WOULD STILL HAVE TIME TO RECEIVE THE DATA AND FINISH THE CHKLIST BEFORE THE TWR WOULD BE READY FOR US. MEANWHILE; I SWITCHED TO TWR FREQ AS THE FO WAS PULLING DATA OUT OF THE ACARS PRINTER AND SHOWED ME A NEW TPS FOR RWY 18L WITH A WT 1000 LBS BELOW OUR PLANNED TKOF WT AND THE CURRENT TEMP AND UNDERSTOOD HIM TO SAY 'WE GOT IT' AS HE LOADED INFO INTO THE FMS AND TRC. I REVIEWED THE TKOF DATA ON THE NEW TPS AS BEING 'TEMP AND WTS GOOD AT 1000 LBS BELOW PLANNED; BUGS ARE RESET AT 131; 131 AND 135; 1.62 EPR FOR FLEX PWR FOR RWY 18L; SET AND XCHKED.' IT WASN'T UNTIL APPROX 20 MINS AFTER TKOF; IN A SUBSEQUENT CONVERSATION WITH THE FO; THAT I REALIZED THAT WE HAD NEVER RECEIVED A FINAL LOAD CLOSEOUT. AT THIS POINT I CONTACTED LOAD CTL; VIA RADIO; AND INQUIRED AS TO OUR PAX COUNT; ETC; AT WHICH WE WERE SENT AND RECEIVED A FINAL CLOSEOUT. IN RETROSPECT; I REALIZE THAT I PROBABLY RUSHED THE FO THROUGH THE FINAL CHKS AND SHOULD HAVE SIMPLY NOTIFIED THE TWR THAT WE WOULD BE DELAYED A FEW MINS. I WOULD NOT HAVE DEPARTED WITHOUT THE CLOSEOUT; BUT SOMEHOW ALLOWED THE NEW TPS TO TAKE THE PLACE OF THE CLOSEOUT AS I REVIEWED THE DATA. I THINK ESTABLISHING THE HABIT OF ACTUALLY HANDLING THE CLOSEOUT; AS OPPOSED TO HAVING THE FO'S HOLD AND REVIEW IT; WILL PREVENT THE MISUNDERSTANDING FROM OCCURRING AGAIN.
