Question about Native Airbus A330-900 Neo Aircraft

[jlabit]

I recently uploaded and installed the aircraft addition listed above and I'm having a question about it. The listing indicates that the range of this aircraft is 13,300 km, which is about 8,265 miles. Taking off from JFK in New York City, I am unable to reach London, UK without fuel starvation, after maxing out the fuel tanks. According to the fuel placard, I am carrying 46,900 pounds of fuel with tanks completely filled. Anyone know if I am doing something wrong with the installation? I put the file into my community folder as directed, and it shows the aircraft available on the startup menu.

I'm by no means an expert here but I got curious about your problem. I looked in the website "Modern Airliners" and found the max fuel load for a A330-900neo is 139,090 litres.

Converting 139,090 litres to U.S.Gal = 36,744 (approximately)

Converted 36,744 U.S.Gals to Lbs = 249,859 Lbs.

So it looks like your fuel load is the problem. So if your tanks are completely full with 46,900 lbs there must be something amiss with the fuel tank arrangement.

I hope this helps.

Wow - good job neither of you guys fly airliners in real life.
1 litre is approx. 2.2 lbs so 139090 litres is approximately 306,000 lbs of fuel.
1 us gallon weighs 8.345 lbs so 36744 gallons is 306, 628 lbs.
Crashed and burned.

Well - I am also wrong as I used the weight of water per litre and not the weight of jet fuel.
Jet fuel weighs 6.84 lbs per gallon so 36744 gallons will weigh 252400 lbs approximately.
Back to school

Apology accepted. No big deal, we all step in it once in a while. Keep on posting!

Now we haven't heard from jlabit to see if he fixed his problem or not.

Needs to check the "aircraft" cfg file.
Go to the section[Fuel[ and change the figures to match the above - which will give 36750 total figure

Thanks for the responses to my question. NTHNYDS, I am great at building computers and computer hardware, but very unknowledgeable about software. With that in mind, I have found a folder called Community, headwind a330-neo_v-0-92, SimObjects, Airplanes, Headwind_A330neo, flight model. which brings up the flight model in Notepad. Under the fuel heading, I have changed the files to the figures you suggested, but I am not seeing either the left or right aux tanks configured on the aircraft and still have 46,895 pounds of fuel with tanks maxed out. Please keep in mind that you are dealing with a 71 year old. Am I changing the wrong files?

Hi Jlabit.
I don't have the aircraft so can not "see" what you are seeing. Where did you download it From?
Secondly, let's see if we are on the same "page."
Can we confirm that you are indeed talking fuel by weight - pounds, and not by quantity, gallons.
If you load up the aircraft in FSX, before you click on "fly now" you should be able to open the fuel settings where you are able to change the fuel quantity before finally loading the aircraft into FSX and flying. This should tell you if the quantity is in gallons or pounds. It will read so. You have the option to show the fuel quantity in either gallons or by weight, and also to change the amount in all or any of the tanks from here.
It probably is not possible to add additional fuel tanks into the "air" config file if they are set in the aircraft model, but you can change the maximum amount of fuel in each tank in the "air" config file.
If indeed the amount of fuel is shown in pounds and not gallons then change the values in the "air" config file to show the maximum amount of fuel, in pounds, that this aircraft can carry. You have that figure in previous posts. Then spread this total value over the number of tanks you have. Save the file and then load the aircraft into FSX to check that the changes are indeed now shown. Any variations you need to make in fuel carried - for short or long flights - do this in FSX and not by changing the "air" file once you have set it correctly to the maximum fuel this aircraft can carry.
If, however, the figures you give are "gallons" and not "pounds", then we have a different problem that we can discuss once you have clarified the above.

One question I should have asked right up front. Are we talking about FSX or MSFS 2020?
All the responses I have given are for FSX. I do not have MSFS 2020 so cannot help if that is the case.

[jlabit]

Sorry, nthnyds, I should have stated in the thread start that I am talking about an A330-900 that I downloaded from this website, and that it was for FS 2020. Guess I should just stay away from this addon aircraft unless I just want to fly within the U. S. Thanks. I appreciate your trying to help.
