Kenparry: I think we are not on the same page here..I did not imply that I want to unbalance my T/O, my point being; it is possible to alter your speeds. Balanced field is not very relevant, because then we are talking about the TOD available versus ASD available. What the term balanced T/O refers to is of much higher relevance. Here we compare our actual TOD versus our actual ASD with the current GW and conditions. And it is here we can get the advantage of having a balanced T/O, which in essence means that we have the optimum relationship between TOD/ASD and therefore giving us equally "excess" distance in both the GO case, and the STOP case.
What we are after here is to be allowed to have the highest possible GW and at the same time being safe.
