I notice that the B744 of Ifly has lack of engine power when using real living perfomance tabels in Project Magenta from FL250 on.Where can I find the parameters to increase the power of the engines. I suppose I have to do it in the ircraft.cfg, but I don't know which item ? Many thanks Michel

To change just the thrust at higher altitudes, you will need to adjust some parameters in the air file, which is binary. There are tools out there that you can use to do this, however unless if you are comfortable with them I would suggest you let someone else do it for you.If you will PM me and attach your .air file I'll take a look at it.Regards,Sean

Michel,search for answers in AvHistory:http://perso.wanadoo.fr/hsors/FS_Soft/index.htmlfor editorshttp://perso.wanadoo.fr/hsors/FS_Soft/fsairfile.htmlfor forum supporthttp://www.avhistory.org/scripts/MegaBBS/f...w.asp?forumid=5It depends whether you want performance to match the flight manuals or just a quick fix.Ian

I Sean , Ian,Thanks a lot for these very interesting links Greetings Michel
