747-400 MZFW

[kmanning 12]

Hi,

I noticed that there are 2 different values for the MZFW of the 747-400. In the Load Manager, it shows a MZFW of 542,500 lbs. In the PMDG Limitation Manual, it says the MZFW is 535,000 lbs. Why are there 2 different values? I also have another question. When I select full passengers in the Load Manager with the Tri-Class Configuration, it indicates a passenger weight of 76,680 lbs. When divided by 180, which is what the Load Manager uses to calculate the average weight for each passenger, the answer is 426 passengers, which I assume is the maximum number of passengers seats in this configuration. But in the aircraft.cfg file under General, it says nSeating: Typical 3 Class Configuration - 416. Why are these 2 different?
