Sean, what I would be interested in knowing is the MZFW for 752 and how much % the 3 tanks must be filled in to come to MTOW. I'm quite sure the 757 cannot take MZFW and 100% full tanks and still be within MTOW. Hence the question above. The ACE is doing bad work in this area as even full pax & cargo you can fill up 100% fuel and be less than MTOW. I had checked some years before and think the total fuel capacity of the CS 752 is well short of the real 752 (same apply for CS 767 I believe)

I think the best think is not work with ACE and manually insertions.
Q. Sean; Do you know the right Fuel Factor CS752 on a Simbrief Airframe?
Thanks Buddy
