Narrative:
PF (first officer) reported aircraft very nose heavy and unresponsive during rotation. Following flap retraction; 'speed low' annunciated 40 KTS above flap retract bug. Flight planned at FL280 for turbulence actually flown at FL320-FL340 for fuel conservation; yet arrival fuel was less than planned. Approaching oak at 10000 ft in straight and level unaccelerated flight; alpha speed was found to be 237 KTS while clean. Approach speed chart showed this to correspond to a gross weight of 134000 pounds versus closeout predicted 122000 pounds. Approach bugs were set and flown accordingly. EPR on stabilized final with flaps 40 degrees was normal 1.23 using higher speeds. After landing; approach stabilizer trim was found at 10 degrees anu.

Title: THE WT AND BAL DATA GIVEN AN MD83 CREW BEFORE FLT WAS NOT ACCURATE FOR THEIR TKOF; CRUISE; OR LNDG PERFORMANCE.
Narrative: PF (FO) RPTED ACFT VERY NOSE HVY AND UNRESPONSIVE DURING ROTATION. FOLLOWING FLAP RETRACTION; 'SPD LOW' ANNUNCIATED 40 KTS ABOVE FLAP RETRACT BUG. FLT PLANNED AT FL280 FOR TURB ACTUALLY FLOWN AT FL320-FL340 FOR FUEL CONSERVATION; YET ARR FUEL WAS LESS THAN PLANNED. APCHING OAK AT 10000 FT IN STRAIGHT AND LEVEL UNACCELERATED FLT; ALPHA SPD WAS FOUND TO BE 237 KTS WHILE CLEAN. APCH SPD CHART SHOWED THIS TO CORRESPOND TO A GROSS WT OF 134000 LBS VERSUS CLOSEOUT PREDICTED 122000 LBS. APCH BUGS WERE SET AND FLOWN ACCORDINGLY. EPR ON STABILIZED FINAL WITH FLAPS 40 DEGS WAS NORMAL 1.23 USING HIGHER SPDS. AFTER LNDG; APCH STABILIZER TRIM WAS FOUND AT 10 DEGS ANU.
