Did you use the data from http://fuelplanner.com/? For SIN-NRT in the A380 the total fuel is 224628 pounds, I don't like the defult fuel planner in FS9 I always use Fuel Planner, I enter that 224628 value into all the entries and it just does not change at all and resets it's self automatically.

 

Ok, whoa!!  Hold on a sec.  You're saying that you are trying to enter 224628 into each tank??   If so, that's your problem right there.  No one fuel tank on that plane can hold that much fuel, and once you make a bad entry into the fuel tanks, you're going to be stuck in that error loop, no matter what you do afterward. 

I have no idea how deeply the fuel system is modeled on this aircraft as far as what tanks need fuel and which can go empty or how it's fed, but assuming that it's a simple modeling and it doesn't really matter, you need to divide the total fuel by 7 (there are 7 fuel tanks).  224628 is the total fuel that you need on board.  Go into the fuel loading page and in the first five tanks enter 37606 lbs.  Don't worry if the number changes a little.  Just accept whatever value it rounds to.  In the last two entries (the tip tanks), leave them at 100% as they each only take about 18000 pounds.  After all this you should see a total fuel load of 224732 lbs.  Don't try to get the exact number you wanted, it won't happen.  One hundred extra pounds is nothing. 

So to summarize:

Total fuel (224628) - Tip tank fuel (36598) = 188030 /5 (number of remaining tanks) =37606.  Make sense? 

If I misunderstood you, my apologies.  Let me know.

Cheers,

Thanks Jeff, I was wondering what I was doing wrong, so for future reference I take the total amount of fuel provided by Fuel Planner and devide it by 7 as you said and then put that number into the fuel entry's?

Just follow the formula I gave you in the last post.

Total fuel (224628) - Tip tank fuel (36598) = 188030 /5 (number of remaining tanks) =37606.

In this case there are 7 tanks, but the two tip tanks only hold about 18000 lbs each.  So subtract the total weight of the tip tank fuel from the total fuel required, first, and then divide that number by 5.  That should keep you out of trouble.  :wink:

Let us know if you have any more problems with it.

Cheers!!

Jeff you are a genius, I'd buy you a beer if you weren't so far away, I managed to load up fuel without any problems what so ever, thank you so much for your help, I feel like I should do something for you lol.

Just enjoy your plane and try to learn something new about flying on every flight.  That will be ample reward for me.

Good luck and have fun!!

Just an FYI, in most planes, you want to fill the wing tanks first before you start filling the center tanks. And I say most because I know in the Citation X, you want at least 500 pounds in the center tank for ballast. With some more complex aircraft, like the PMDG 747-400, it gives you a fuel loader where you enter how much fuel you want, and it automatically figures it out for you. With something like the Project Airbus A380 or even Project Opensky aircraft, you're left to figure it out on your own, so that's something you want to keep in mind.

Kev, which aircraft is it that you almost have to use an external fuel loading app or it messes up how the fuel system functions?  Is it the PMDG 47 or another one that I'm thinking of?

Affirmative, sir. PMDG 747-400 has its own fuel loader. Presumably other PMDG aircraft have it as well.

Ok thanks!!  I didn't feel like hunting through all my manuals.  Been a while since I flew that one.  I know with the 37 I can do it either way, but I knew there was one of my planes that if I tried to enter fuel values in FS manually it would cause some issues with how the fuel system functions.  I couldn't remember if it was that one or the Flight1 ATR.  Thanks again.  :smile:

This has a chance of happening in all aircraft when using the FSX fuel dialogue where, and only where, at least one tank is 100% full.

 

If a tank is 100% full, change it to be either 99.9% full or 99.8% full.

 

FSX 'rounds up' sometimes, so if 1999 is "full" and you enter 1999, it tries to round up to 2000, which is of course 100.1% of maximum capacity - not possible.

Reduce the fuel load till it's rounding up to something less than 100% fuel.

Could be both for all we know. I don't know anything about the Flight One ATR, so I can't comment there. I only know the PMDG Boeing 747-400 because not only do I have it, but I actually flew it today and subsequently had to load fuel for the flight.

Oh you don't have that one??  You really should try it.  It's right up there on the PMDG scale.  The manual for it is like 800 pages, with all the performance charts and graphs you could wish for.   I've got it printed out in a 4" loose leaf, lol.  Awesome plane!!

Never was really big on turboprops. I mostly fly the big jets, although I have done a bit of helicopter flying before.
