Narrative:
During power advancement, the takeoff warning horn sounded and I called for abort. The aircraft was stopped. Upon review, the CDU switch was in the normal position rather than the top position. It is evident that this PIC failed to position this switch correctly during the previous flight's descent checklist. Other factors: my company has revised (reorganized) the checklist several times (in excess of 5) since the 3 yrs I have been flying this aircraft. Possible factor: this was my 88TH departure in 4/91.
Original NASA ASRS Text
Title: FLT CREW REJECTED TKOF ACCOUNT WARNING HORN. THE TKOF POWER SWITCH HAD NOT BEEN CHECKED IN TKOF POSITION.
Narrative: DURING PWR ADVANCEMENT, THE TKOF WARNING HORN SOUNDED AND I CALLED FOR ABORT. THE ACFT WAS STOPPED. UPON REVIEW, THE CDU SWITCH WAS IN THE NORMAL POS RATHER THAN THE TOP POS. IT IS EVIDENT THAT THIS PIC FAILED TO POS THIS SWITCH CORRECTLY DURING THE PREVIOUS FLT'S DSNT CHKLIST. OTHER FACTORS: MY COMPANY HAS REVISED (REORGANIZED) THE CHKLIST SEVERAL TIMES (IN EXCESS OF 5) SINCE THE 3 YRS I HAVE BEEN FLYING THIS ACFT. POSSIBLE FACTOR: THIS WAS MY 88TH DEP IN 4/91.
