Hey guys, I have only recently started using FSBuild to plan my flights accurately and all I can say is I'm sorry I didn't get my copy earlier. However, I have noticed some discrepancies regarding fuel burn when using FSBuild for fuel planning purposes. Namely. My 744 will burn about 4000 lbs above what FSBuild predicts for climb but during cruise I end up saving up on fuel since FSbuild estimates a higher than actual fuel burn. And believe me when I say I use high Cost indexes (M85 and above)So, all this to ask whether anyone knows where can I find accurate PMDG aircraft profiles for FSBuild (both 737 and 747)?Many thanls in advance Best Regards,Victor LimaSBGLhttp://www.precisionmanuals.com/images/forum/800driver.jpg

are you currently using the ones posted on the FSBuild website for these specific aircraft and developer? They do not come with the package at the time of purchase (I believe)

Oh I didn't know about those. thanks for the info! Will give them a try.I've been flying around at optimum altitudes and recording the observed fuel flows. I believe in a little while I'll have enough data to make my own PMDG profile for FSBuild, which hopefully will be extremely accurate.Best Regards,Victor LimaSBGLhttp://www.precisionmanuals.com/images/forum/800driver.jpg
