Classic British Flight Sim

I have a single engined jet acft with two fuselage tanks and two drop tanks. I need to equalise the rate of fuel feed from the two fuselage tanks to maintain a good CofG.

At present my 'aft' tank empties before the 'front' fuel tank starts to empty thus making for a nose heavy moment.

Can a forum member please tell me what alterations I have to make to the acft cfg to ensure that such a balance is maintained?

Make the two fuselage tanks the same size and position them the same distance from the CofG like this:-

Place these two lines under the other tanks lines in the [Fuel] section:-

LeftAux = 10.00, 0, 0, 1786, 0 //Longitudinal (feet), Lateral (feet), Vertical (feet), Usable(gallons), Unusable (gallons)
RightAux = -10.00, 0, 0, 1786, 0

The LeftAux is the front one (10.00 feet foreward of the CofG)
The RightAux is the rear one (-10.00 feet rear of the CofG...NOTE the minus sign)

FS9 will empty these tanks before using the main wing tanks and as they are the same size they should empty together and because they have opposite but equal moments on the CofG, the CofG should remain stationary.

To behave in this way the tanks really need to be called what I have called them (not sure if they will work if called FrontAux and RearAux)...It is an FS9 thing and does not need any extra pumps or cocks to work.

For Peter:
Many thanks Peter, your modification worked well.
