Thanks Pete. I will try it.

I'm looking the way to modify the fuel-quantity for several tanks in FS2004. We are implementing the fuel flow in C. The visual representation is made with XML reading the Quantity variables, and have no problems with this, but we can't set the fuel quantity calculated in the C routines. I read last year post with the same problem, but without solution. Do you know how to decrement fuel quantity in the tanks?. I don't found the offsets for following variables: FUEL_QUANTITY_RIGHT, FUEL_QUANTITY_LEFT, FUEL_QUANTITY_CENTER and FUEL_QUANTITY_CENTER2. The tanks fuel LEVEL (in percent).. make same function? ie, changing the tank level, FS change the fuel quantity automatically.. is this correct?
