Interesting Question...
At first glance, I guess moving some pax forward would help. Next, I'd wonder why forward hold, but read hold was in-op. Did you learn the cause? I know little of the A320 series, including CG issues, but @750XL says that they are not a 'tippy' as many others. (As I recall, the B727 and DC-9 series were (are) famous for tipping back onto their tails when rear loads are imposed before forward loads.) Again, did you ever learn WHY the forward hold was INOP? What your fix to achieve dispatch?
