Hi
I think you want to create digital response for generating trim sheet.
You perhaps need to know as to why there is variation in H-arm of AHM and WBM say for pilot position, row arms, understand from where AHM shows 500 kg multiple of fuel whereas WBM is in multiple of 400 ltrs.
If you know as to how the trim tab calculation is arrived at please share with me
All the best for your mission.
