Hey all,Doing a new plane, a jet this time. I cant figure out what my fuel tanks should be as all the websites on this plane are in pounds. I did find a note that says the plane carried a total of 847 gallons.I have two wing tanks, two tip tanks, and two fuselage tanks. I know that the fuselage holds 1800 lbs. The wings are 1141 lbs. The tips are 368 "gallons"? (all I could find). and if I do the math, it comes out crazy. I look up Jet-A fuel online at several websites, and it states Jet-A weighs 6.79. That"s basically nearly 7 lbs, or 6.8. Most fuel is measured (I thought) at 6.6. I now find out that Airliner pilots are trained to go by 6 lbs per gallon. When I calculate to the best of my abilities the tanks on this bird, it comes out to 6.4.I "thought" or figured that fuel in FS is at 6.6 lbs. Now Im not sure if that is correct, getting blurry here, and coudnt find fuel weight in the FS2004 SDK in the Aircraft Container doc. Surely its in there, but I am missing it, I guess. (Just looked again and didn"t find it).So, my question is, what is FS fuel weight, Jet-A, per gallon.I guess I can fudge this, but I hate too. I have been looking for 2 days now for gallons per tanks on a Learjet 23 and have found NOTHING... Talk about ways to accelerate gray eyebrowing of the eyebrows, converting them into shiny, silvery, aluminum like antennae...

I got it. Figuring it around 6 lbs per gallon, I adjusted the wing tanks to balance out the total.Fuselage....1800 lbs.....300 GalWings........1141 lbs....190 GalTips...........2142 lbs....357 GalTotal..........5083 lbs....847 Galwhew...

Hey Bill here is a bit of reference material for the Lear. This is the settings for the Lear 25D fuel cfg in my fs9 setup and it is pretty much spot on.External1 = 0.000, 0.000, 0.000, 195.000, 2.000LeftMain = 0.000, -8.000, -0.300, 173.000, 3.000LeftTip = 0.000, -19.950, -0.200, 184.000, 2.000RightMain = 0.000, 8.000, -0.300, 173.000, 3.000RightTip= 0.000, 19.950, -0.200, 178.000, 2.000//////////////////////////Total fuel 6055lbs--903galls--//////////////////////////Like I said, the above is for a 25D and the 24"s and 23"s had less fuel. I attached two pictures for you. One is the fuel panel from the Lear 24 and will give you the numbers that you most likely need to use. The other is from a 25B and holds a bit more in the fuse tank.6.7 is the nominal value for JetA (trust me, I pumped it for 13 years). It can vary in density from 6.6-6.8 so 6.7 is ususlly the "normal".If you use 139 gallons for the External1 tank for the Learjet23 it will yield 847 gallons total.The External1 trick works good too as it burns out of the fuselage tank first as it does in real life.Hope this helps Greg
