After one Ramp Start I don't have the same fuel quantity...

[Skulleader]

Hello,

 

I need your explanation, I have created one mission with a Ramp Start for my A-10C and after have switch ON the battery and Inverter I've noted that the fuel quantity is not the same in my left and right tanks.

In my Editor Mission I have 100% of fuel.

 

I join you one screenshot for show you that I explain to you:

 

 

 

Please can you tell me if you too you have the same quantity of fuel after one Ramp Start ?

 

A great thanks in advance for your assistance. Skull

My test button has never shown me a perfectly symmetrical fuel load. I recall always having 5900 on the test total.

 

Asymmetry could be due to the APU drawing only from one tank (via the DC Fuel pump). Is this only before you start APU or after?

Hello,

 

In fact I do not start the APU, just the battery and the inverter, I join you one little video who show this asymmetry from my Youtube...

 

 

Thanks again, Skull.

I'm sure you know, that's more or less how it's supposed to work. When the indicator's working, using the indicator test button will make the needles move to the 3 and 9 'o clock position and the totalizer will show around 6,000 pounds. It's close enough for government work, and I wouldn't worry about it.

If you press the test switch, the indicators should indicate a certain amount, within a tolerance. I can't recall them on the top of my head, you'll have to check the manual.

Just checked the dash-1:

 

8. Fuel quantity - Check.

 

a. Test indicator button - Depress. L and R pointers

will read 3,000 (±300) pounds, totalizer

will read 6,000 (±400) pounds.

 

b. Fuel display selector - Verify total by checking

in each position and reset to MAIN.

 

NOTE

 

Fuel gauge indicator tolerance is ±600 pounds of

actual fuel loaded on the aircraft. Regardless of

indications given during the fuel quantity indicator

test, the fuel quantity indicated by the needles

and gauge totalizer may be higher or lower than

actual fuel available by ±150 pounds per system

L/R Wing and L/R Main.

I have noticed those differences too.

 

Maybe airplane itself doesn't have 100% symmetrical weight distribution.

So, the reason for this small difference in fuel quantities could be to balance the airplane.

Something I just noticed and should add:

 

Notice how you are not looking straight at the gauge. You're looking at it from an angle.

Try looking at it from straight ahead.
