Narrative:

During preparation for start I informed the flight attendants there would be a short taxi for takeoff. We were given a taxi clearance to runway 33. ATIS reported calm winds, however, ATC gave wind as 190 degrees at 6 KTS during taxi, giving a 4 KT tailwind. About 1/2 way through the takeoff roll the first officer advanced the power about 3 EPR due to slow acceleration. We lifted off about 800 ft from the end of the runway using a normal takeoff profile for flaps 5. After takeoff the first officer looked up the performance for runway 33 and discovered we were 1400 pounds overweight for that runway. Factors contributing to the overweight takeoff were rushing to get all checklist items done for the short taxi, and not taking the time to page through all of the ACARS weight and balance data. Neither myself or the first officer caught that the ACARS takeoff data we were using was for runway 6, not runway 33. The problem could have been avoided by looking up the performance data before taxi with an estimated takeoff weight. All 3 pages of the ACARS weight and balance data should have been paged through as a xchk.

Title: UNAUTH TKOF PROC DOWNWIND TKOF REDUCED THRUST TKOF RUN.

Narrative: DURING PREPARATION FOR START I INFORMED THE FLT ATTENDANTS THERE WOULD BE A SHORT TAXI FOR TKOF. WE WERE GIVEN A TAXI CLRNC TO RWY 33. ATIS RPTED CALM WINDS, HOWEVER, ATC GAVE WIND AS 190 DEGS AT 6 KTS DURING TAXI, GIVING A 4 KT TAILWIND. ABOUT 1/2 WAY THROUGH THE TKOF ROLL THE FO ADVANCED THE PWR ABOUT 3 EPR DUE TO SLOW ACCELERATION. WE LIFTED OFF ABOUT 800 FT FROM THE END OF THE RWY USING A NORMAL TKOF PROFILE FOR FLAPS 5. AFTER TKOF THE FO LOOKED UP THE PERFORMANCE FOR RWY 33 AND DISCOVERED WE WERE 1400 LBS OVERWT FOR THAT RWY. FACTORS CONTRIBUTING TO THE OVERWT TKOF WERE RUSHING TO GET ALL CHKLIST ITEMS DONE FOR THE SHORT TAXI, AND NOT TAKING THE TIME TO PAGE THROUGH ALL OF THE ACARS WT AND BAL DATA. NEITHER MYSELF OR THE FO CAUGHT THAT THE ACARS TKOF DATA WE WERE USING WAS FOR RWY 6, NOT RWY 33. THE PROB COULD HAVE BEEN AVOIDED BY LOOKING UP THE PERFORMANCE DATA BEFORE TAXI WITH AN ESTIMATED TKOF WT. ALL 3 PAGES OF THE ACARS WT AND BAL DATA SHOULD HAVE BEEN PAGED THROUGH AS A XCHK.
