I have been using this one from fuel.aerotexas but it seems to aim way to high. Giving me about 15.0 reserves and it doesnt seem to be the best option because you cant adjust the payload. I'd rather not have to pay for a fuel planner either. Does anyone have a better alternative than just guessing or using the one from aerotexas?

This has been beaten to death and a quick search would have enlighted you. But, anyways, this is my favorite:http://www.volny.cz/...FPL/B737FPL.htmIt gives the same fuel load as vRoute Premium, to within a couple of hundred pounds. It can also retrieve the payload from FSX, but don't try to load fuel with it into the NGX. Use the CDU for that.

The best fuel planning for the NGX is to use the Fcom's and the Fuel option in the CDU. Nothing else is needed.

BTW, I've been meaning to try that... what chapter of the FCOM deals with fuel planning?

I use the old PMDG NG fuel planner, though I haven't checked on accuracy

if you dont have a FPPM and / or you dont want to pay : i ve no ideas to help you. Fsbuild, FOC Danur 2003 (even with no new navdatas) are great on their profiles side (of course i ve made some lol). if you check some of my posts on this forum you ll get some infos for pre planning then adjust with the fms if again you dont want to pay or dont have a FPPM .... all the best and good luck.

Just estimate and if you've got too much just drop it abit....

I use the FMC. It's very accurate
