Captain Maziarz, Thank you very much for your detailed TUTORIAL. Although I followed your instructions, I could not get something close to 122.7 but 139.7 of ZFW, on the page 0.00.36. What is the matter? Otherwise, on the FSX Aircraft menu, Empty weight: 91300 Pounds, Payload: 48350 Pouns thus ZFW: 139650 Pounds. Sincerely, Kan-ichiro Fushihara

Which FSX Aircract menue do you mean? You should load the plane with the CDU. And you shouldn't touch the default FSX fuel and load menues.

As you said, I have loaded Fuel and Payload on the CDU page 0.00.12 ~ 0.00.14. I have only looked FSX Aircraft menu to check.. Sincerly, Kan-ichiro Fushihara
