Urm… I found that the absolute pessenger/baggage weight of “100% payload” (slide forward) is different when I choose fuel in 0% and 100%. Apprentely the payload includes fuel. i.e. unrealisticly you can achieve MTOW by filling lots of passenger/baggage without fuel.
Since 787 is having different configurations e.g. different class/absence of first class etc., I have no idea the value (in lb) of “maximum passenger and cargo”. Any suggestions?
