Balanced Moment,
Thanks for that ... I'm now briefed re the lateral limits and MTOW ... makes the earlier comment quite understandable.
I'm not aware of any requirement for such a severe design case as you suggest ... the normal limits are associated with lateral handling qualities .. particularly for takeoff and landing .. to ensure that there is enough aileron authority in crosswind conditions.
As for SW ... as you suggest .. if one restricts the limits and, if necessary, ballasts the aircraft to give a reasonable passenger flexibility .. so be it ....
I would be more interested ... with part loads ... what do they do to give the pilots some indication of stab trim for takeoff ? I guess that there is a cabin crew protocol to figure a pax distribution from which the tech crew can figure a reasonable cg... only a concern with a severe mistrim .. but the case of a very aft cg with a trim set for forward cg makes for an interesting departure in a 73....
