## Discrepancy

ON TAKEOFF ROLL AT APROX 1100-120KTS ALL PERFORMANCE DATA DUMPED V1,VR DISAPPEARED SPEED DATA ONLY SHOWED V2 BECAUSE IT WAS SET IN SPEED WINDOW.  COMMANDED ROTATE AT V2 & WE CLIMBED OUT AT V2 20.  SET 240 IN WINDOW FOR CLEAN UP ON SCHEDULE AT 3500 FT.  ENGAGED AUTOPILOT WHERE IT MAMED A PITCH OVER INTO A DIVE, NOT THE CLIMB THAT WAS COMMANDED.  DISENGAGED THE AUTOPILOT & RE-GAINED CNTL OF THE ACFT.  WE CONTROLLED OVER CLIMB OUT & SLOWLY THE DATA RETURNED INTO THE FMS.  PERFORMED GPWS GND TEST & AIMS, FMCS TEST IAW MM 34-46-00-5 & 34-61-00-5, ALL GND TEST PASSED.  FMCS CHECKED OK.  RELOADED ALL SOFTWARE OF RT AIMS CPM & STD IAW MM 31-41-05-2.
