ssg, why are you so adamant about using 8000ft or 9000ft or runway? Can't you use percentages please? It makes no sense to say that using 9000ft of runway to rotate if you don't tell us how long the runway is. What it is 12,000ft? Or 15,000ft? Where is the problem of using 75% of a runway to get airborne? Where is the problem of using the full legal amount? Granted not ideal, but a runway is there to be used and so is an aircraft to its legal and sensible limits.
