This I know :) problem is that I do not know what does the function SAVE relate in freight panel - I did not see explanation in manual. Second, ACE, does changes in passenger version automaticaly set plane weight? Also, do I play with ACE before FSX startup or after?

Sorry, I was a bit used to 767 from competition. I do not judge whic his better, I only would like to know how to operate goodies in proper way :)
