a) considerations of BFL, unbalancing, overspeed schedules, etc., are all made before the takeoff as part of the performance assessment. This is done either in the preparation of RTOW tables/charts by the ops engineering folk, or by the pilot in those operations which impose that task on the crew.
As usual JT ---wise and knowledgeable words--- but I was referering to the engineering side--not the end user---i.e if on an earlier type of older certification do you tend to unbalance according to the limiting cert scenario in the RTOW assumptions? is it such that unbalancing occurs mainly in the ASD--but leave the BF for the GO--just wondering how a pro would handle it?---I have looked at the preammendment requirements, but would like to know how such things affect the performance calculations
