TKOF ABORTED.

Narrative

THIS NASA RPT IS BEING SUBMITTED TO HELP DOCUMENT THE IMPORTANCE OF CHKLIST USE AND COMPLIANCE. WE TAXIED OUT ON ONE ENG FOR FUEL PURPOSES. THERE WERE 3 OTHER ACFT AHEAD OF US AND THINGS SEEMED TO BE MOVING VERY SLOWLY. WITHOUT MUCH WARNING; TWR STARTED CLRING OUT ALL THE TFC VERY RAPIDLY. WE WERE CLRED INTO POS WHILE STARTING THE #2 ENG. AT THIS POINT WE DID HAVE A MINOR IDLE PROB WITH #2; BUT CORRECTED IT WITH STANDARD PROCS. WE WERE IN THE MIDDLE OF THE BEFORE TKOF CHKLIST WHEN CLRED FOR TKOF. ONE OF THE ITEMS ON THIS CHKLIST IS TO CHK THE TKOF WARNING SYS. WHEN WE DID THIS; WE RECEIVED THE AURAL WARNING FOR FLAPS. RATHER THAN RUSH THROUGH TO FIND THE FAULTY ITEM IN AN ALREADY HECTIC ENVIRONMENT; I CHOSE TO CANCEL TKOF CLRNC AND TAXI CLR OF THE ACTIVE. AFTER CLRING; WE FOUND THE FLAP SETTING ON THE TKOF CONDITION COMPUTER WAS IMPROPERLY SET! WE INSERTED THE CORRECT 11 DEG SETTING; TESTED THE SYS AND PROCEEDED ONWARD AND UPWARD. THIS ITEM IS A RELATIVELY NEW ITEM ON OUR CHKLIST. I'M GLAD IT WAS THERE AND THAT WE PERFORMED IT AS ADVERTISED.
