I like to ask 2 questions to the designers:1) Why you made the aircrafts ZFW so high that - with full fuel load - it definitely exceeds the Max. TOW?2) At 50% fuel load the plane burns over 30,000 lbs/h fuel at FL35 and Mach 0.84 ( ISA conditions ). With that fuel burn you get a range of 4,400 NM at the best whereas over 6,000 NM at full pax load are specified.Please give me some advise how to make this aircraft more realistic?

I would ask this in the POSKY forum and maybe check out the FAQ on this bird
