Narrative:
We planned a flaps 2 degree takeoff and had a #2 engine start malfunction. Talked to maintenance and solved problem. On taxi out, inadvertently set the flaps to flaps 1 degree. Takeoff data for flaps 1 degree and 2 degrees were the same. On the takeoff roll at 80 KTS, noticed flaps set to 1 degree and set the flaps to 2 degrees and continued the takeoff rather than abort. The distraction of the start malfunction may have led to this. However, extra diligence may also have helped.
Original NASA ASRS Text
Title: A320 FLC RECONFIGURED THE FLAP SETTING ON TKOF ROLL AFTER THEY DISCOVERED THAT THEY HAD NOT SET THEM AS AGREED DURING PRETKOF CHKLIST.
Narrative: WE PLANNED A FLAPS 2 DEG TKOF AND HAD A #2 ENG START MALFUNCTION. TALKED TO MAINT AND SOLVED PROB. ON TAXI OUT, INADVERTENTLY SET THE FLAPS TO FLAPS 1 DEG. TKOF DATA FOR FLAPS 1 DEG AND 2 DEGS WERE THE SAME. ON THE TKOF ROLL AT 80 KTS, NOTICED FLAPS SET TO 1 DEG AND SET THE FLAPS TO 2 DEGS AND CONTINUED THE TKOF RATHER THAN ABORT. THE DISTR OF THE START MALFUNCTION MAY HAVE LED TO THIS. HOWEVER, EXTRA DILIGENCE MAY ALSO HAVE HELPED.
