Hi Markoz, yes I think also the manual is wrong. No big deal anyway. What bothers me is the max fuel load, I feel really wrong to be able to load full pax & cargo and full fuel. Too good to be true. I don't fly long distance but if doing so it might be an inconvenience if I miss about 20'000 LBS of fuel. Any chance to change that in the cfg file ? But then also in the FMS ?  Weird.

If I want to fly with "full" passengers, cargo and fuel, I generally lower the weight of the cargo in the "ULD's".

So my setup for the Captain Sim 757-200 would be:

Empty Weight	130875
Captain & FO	340
Crew	510
172 Passengers @150 lbs each	25800
Cargo (9 x ULD's @2545 lbs each)	22905
Maximum Fuel	75549
Maximum Weight	255979

If I was to change the Max Gross weight in the aircraft.cfg for the 757-200 to 255000, instead of it being 256000, then I would simply reduce the ULD weight to 2433 lbs ea. so I would still have it close to MTOW. Looking at the data for the B757-200 on wikipedia (which looks the same as what you can get from Boeing.com), it has the capacity (after adding the EW + Max Fuel) to carry a payload of 50,503 lbs. My payload from above, is only 49,555 (almost 1000 lbs less), so it's pretty close IMO.

The truth is that the passengers probably should weigh more than 150 lbs each. Say about 180 lbs each?

[edit]If I wanted to change it from 150 to 180, I would change it in the aircraft.cfg using Edit > Replace (CTRL+H) and start it at the [WEIGHT_AND_BALANCE] line.[/edit]
