Hi Captains,I want to share an Excel document that I made to compute the necessary fuel into Boeing 747-400 and 747-400F.I am posting this file free to be shared by everyone that needs it. You can download it from:http://www.mediafire.com/?lusijcrep4c4tb9The good thing of this fuel planner is that you can modify it as you want.The Excel document makes the computations in exactly the same way that you will do manually following the PMDG/Boeing manual.It works in lbs and in kg.Hope to be useful. Enjoy!Mario GalindoVATSIM 870255IVAO 330807email mariogalindoq@gmail.comP.D.: If you like this file or you hate it, please let me know writing some note here, this will allow me to improve the program.
