Thanks
OK of all the views and only 1 answer i wonder if i posted this in the wrong place? Anyway thanks for your reply. It wasn't really the answer i was looking for. I do understand about trim and the setting of, for example, TPI or the equivalent, also that at higher speeds control surfaces being more responsive to the airflow across them. That said it was more in relation to how much the few passengers crammed together would affect it. If they had spread them out a bit more the trim calculations could still have been done and it seemed that the total effect or that movement wouldn't put the aircraft out of (or make it unable to be trimmed) IMHO it seemed it was being done for ease to the dispatchers/movers rather than for the comfort and service to passengers...
Also i'm not entirely sure the stabiliser/TPI settings will have a huge affect on V1 or the point from which you can abort a take off....
