Quite often when I try to add fuel to an aircraft I get the message: "Please enter a number between 0.00 and XXXX.XX which is exactly what I have done. This seems to happen when you try to add fuel to a tank that has some fuel in it but is not full. It will let you fill up an empty tank sometimes but not one that has some fuel in it. Does anyone know anything about this, why it happens or if there is any kind of work around?

You need to delete the existing numbers before entering the new amounts that you want.
It is not possible with an operating system later than Windows XP to just add to what is already present.

Hope this helps.

Thanks for your reply Paul. First of all, I am using Windows XP. Secondly, I am deleting the previous numbers ie I put the cursor in the % box, delete the value there and put in 100. I can do that for all the tanks, but when I click OK, that's when I get the message to enter a number between two values but the numbers in the boxes are between those values. I've tried changing the one that's highlighted to a slightly smaller value but it makes no difference. Any further ideas?

I've seen this happen before as well and I know there is a way around it. I haven't used the default option for fuel for such a long time I can't remember what I did to get it to work. I tried replicating the issue but right now it's working without a hitch!
Try a general google of the issue. You could also try placing a decimal after the figure you put in. Try it with just a decimal and nothing else, hit ok and if it doesn't work try a decimal and then a '0'
Not sure what I did as I've said but I know it ended up being quite a simple workaround.

You should be able to go to select aircraft pick the aircraft that you are currently in and than select the change fuel/weight option put in what you want and hit enter.
I do no think it will cause you to restart your flight. I have even selected a different aircraft flew that for a while while I changed the fuel in the other aircraft and than went back to it.
I can not remember if this is a fs9 or a FSX feature but I usually use control x and it will automatically put fuel in all tanks of a aircraft.

Still can't solve this problem. There is an event in the assignment list for Add fuel quantity. My assignment is CTRL + X. It works for the Cessna 172, each time you press it each tank goes up by about 1/4 but it doesn't work for aircraft like the 737. Each time you press CTRL + X the gauges go up a few pounds but as soon as you release the keys the gauges go back down. I'm also sure that in the past I've encountered this problem and found a fairly simple solution but just can't remember what it was.

I have never noticed that before. But like I stated the other way is to do what I stated in my first post. That has always worked for me. Another option you can use is to click on the view menu and select map than drag your air craft to where you want it at and hit enter. A word of caution make sure you turn your heading button on and set your current heading as when you come out of the map view you could go into a dive or be heading the wrong way. I sometimes do this on long boring flights. If you are using a flight plan just make a note to where you put your self and than reload your flight plan after removing the way points that you have passed. If you fail to remove the past way points you airplane will go back to them.

Mine has had this problem for ever, sometimes it works, mostly it doesn't but generally I don't fly anything but ifly 737ng so don't get this problem during fuel loading.


Try going to the refueling pad and request refuel.

Having read replies, I went back and messed around and finally got it to NOT work.

I could not set the default Cessna 172 second tank % on two occasions. Both times by messing with the second tank value, a value either above/below/same as the first tank value would go in but may not have been the value I actually wanted for the flight. At this point I accepted ANY value for the second tank, it just had to work. I then did a click in the liters/gallons window of the second tank. After this click I went back to the % window and set the value I actually wanted in the second tank % window and it worked.

Not certain this is the fix, would need to do more testing but it certainly worked twice for me.

Edit: Having thought about it a little more, I think rather than try and set a % in the window that isn't working, just go to the liters/gallons window, put in any value and then click back in the % window for the trouble tank and set the value you want. Hopefully it should now accept it.

Sorry Skywacher, I tried what you suggested but no dice, I get the same message and unable to replenish main tanks.

Damn, ok, if I get a chance I'll have another play but after doing it I am positive it was just a sequence of clicking in the right places in the fuel window that made it work in the past. What I explained did work for me, if I just attempted to change % without going via the liters/gallons window it didn't.

As I stated one way around this is to change aircraft than change aircraft back to what you were flying the plane should load with all tanks full unless you have modified them.
I have noticed that every aircraft in my fleet has all tanks fully loaded as default so no matter when you select them the tanks will be full. Now mind you if you have a aircraft saved as part of a default start up and have changed the fuel in the tanks than this will not work for that aircraft.
Some people such as myself like to start all flights cold and dark and no gas and than add gas according to my flight plan. As a rule of thumb even in the real world pilots will try to put extra gas aboard if they can but sometimes due to cargo and passengers you can not add extra fuel with out removing something to offset the extra weight, Which usually means little or no cargo except for passenger bags..
When I worked a KJAX for Delta we use to have a flight that went to DFW (Dallas Fort Worth) and there were times that we could not put any cargo on board as we had to fill every tank we could with gas. This was a MD88 and it was always tricky loading this flight because of weight and balance issues.They call this aircraft a Load Planners night mere. And believe me it is.

Sometimes it will do this if you decide to display the fuel quantity as weight. Try displaying it as volume (gallons instead of pounds) and see if that helps anything.

Yes, that was the answer, change to volume, fill up the tanks (it will let you then), accept the changes and then change back to weight. Works like a charm, thanks Shane!
