Hi Cameron I have a question: i've found the weight-datas of the aircraft (to use in the PFPX-Flightplanner) in the documentation, except the empty weight. But on Airliners.net i could found that the operating empty weight is about 17'215 lbs. The problem is: when i go into the "weight&fuel"-menu in X-Plane itself and set the fuel and the load to zero, the empty weight is shown by only 12'655 lbs (!). So there is a huge difference of more than 50%, causing problems during loading the needed fuel and load (i have to put much more load to reach the given Take-off-weight calculated with PFPX). Perhaps i'm doing something wrong.... Thanks for your help. Cheers Franz
