I don't fly the 767 just curious, what does the 767 look at for a take-off config warning? I know of a A330 (not QF) that floated long enough to decide to GA then touched down and got a config warning (flaps), so then aborted the GA and continued to land and taxi off. Since then rumour has we should continue to land select flap 2 and rotate at 'F' speed.
