The system of claim 1, wherein the fuel balancing controller automatically controls the fuel balancing valves to terminate the transfer of fuel to the first and second fuel tanks via the balancing fuel transfer assembly. 9. A method for approximately balancing fuel levels between a first fuel tank and a second fuel tank of a mobile platform, said method comprising: reducing the fuel level in whichever of the first fuel tank and the second fuel tank contains a higher level of fuel using a crossfeed fuel transmission assembly to pump fuel from whichever of the first and second fuel tank contains the higher level of fuel through a crossfeed pipe to both a first engine and a second engine to provide fuel for substantially simultaneously operating both the first and the second engines until the level of fuel contained in the first and second fuel tanks is approximately equal, wherein the crossfeed fuel transmission assembly includes the crossfeed pipe fluidly connected between the first and second fuel tanks and a single crossfeed valve for controlling fuel flow through crossfeed pipe; and increasing the fuel level in whichever of the first and second fuel tank contains a lower level of fuel using a balancing fuel transfer assembly to transfer fuel to whichever of the first fuel tank and the second fuel tank contains the lower level of fuel through a fuel balancing pipe until the level of fuel contained in the first and second fuel tanks is approximately equal when a failure occurs in the crossfeed fuel transmission assembly, wherein the balancing fuel transfer assembly includes a plurality of fuel balancing valves automatically controlled by a fuel balancing controller for controlling the transfer of fuel to the first and second fuel tanks through a balancing pipe fluidly connecting the first and second fuel tanks. 10. The method of claim 9, wherein reducing the fuel level using the balancing fuel transfer assembly comprises manually activating a fuel balance switch electronically connected to the fuel balancing controller for initiating the transfer of fuel to whichever of the first and second fuel tanks contains the lower level of fuel, via the balancing fuel transfer assembly. 11. The method of claim 9, wherein increasing the fuel level using the balancing fuel transfer assembly comprises automatically controlling the fuel balancing valves to control the direction of fuel flow through the balancing pipe, via the fuel balancing controller. 12. The method of claim 9, wherein increasing the fuel level using the balancing fuel transfer assembly comprises automatically controlling the fuel balancing valves to terminate the transfer of fuel to whichever of the first and second fuel tanks contains the lower level of fuel, via the fuel balancing controller. 13. The method of claim 9, wherein increasing the fuel level using the balancing fuel transfer assembly comprises automatically controlling the fuel balancing valves to transfer fuel from a center fuel tank to whichever of the first and second fuel tanks contains the lower level of fuel, via the fuel balancing controller. 14. The method of claim 9, wherein increasing the fuel level using the balancing fuel transfer assembly comprises automatically controlling the fuel balancing valves to transfer fuel from whichever of the first and second fuel tank contains the higher level of fuel to the respective first or second fuel tank containing the lower level of fuel, via the fuel balancing controller. 15. A mobile platform fuel system, said system comprising: a crossfeed fuel transmission assembly including: a single crossfeed valve that controls fuel flow through a crossfeed pipe fluidly connected at a first distal end portion to a first fuel tank and fluidly connected at an opposing second distal end portion to a second fuel tank; at least one first fuel boost pump fluidly connected to the crossfeed pipe for pumping fuel from the first fuel tank; and at least one second fuel boost pump fluidly connected to the cross feed pipe for pumping fuel from the second fuel tank; a balancing fuel transfer assembly including: the first and second boost pumps and the first and second distal end portions of the crossfeed pipe; a first defuel valve that controls fuel flow out of the first fuel tank through a balancing pipe fluidly connecting the first and second fuel tanks; at least one first refuel valve that controls fuel flow into the second fuel tank through the balancing pipe; a second defuel valve that controls fuel flow out of the second fuel tank through the balancing pipe; and at least one second refuel valve that controls fuel flow into the first fuel tank through the balancing pipe; and a fuel balancing controller for automatically controlling a transfer of fuel to the first and second fuel tanks, via the balancing fuel transfer assembly. 16.
