Takeoff separation?
I flew out of Malaga recently on a 757 on what appeared to be a very busy morning, and out of curiousity I timed how long it took for us start our takeoff roll after a company 757 departed just before us.
Between the preceeding aircraft and our takeoff roll, it was almost exactly 60 (+/- 1 or 2) seconds. It seemed very slick to me; what are the actual guidelines?
