Hi I have flown few times 747 pmdg for air-child , but every time I go into Flight Briefing suggested pax number only goes up to 375 and I know 747 have about 425 or close is there anything I am missing to load more people . Also I usually take 180 lb. Per pax should include baggage and the payload . I know that breathing gives baggage but into fs build goes only payload . So I would like to know if 180lb per/ pax is enough and if I can load more the 375 pax in Flight Briefing . Thank you petr
