Abstract
An aircraft fuel system having a fuel tank and a baffle dividing the fuel tank into a primary fuel containing space and a secondary fuel containing space. A fuel drain is provided through which fuel flows from the primary fuel containing space into the secondary fuel containing space. A primary fuel outlet draws fuel from the primary fuel containing space and a secondary fuel outlet draws fuel from the secondary fuel containing space, wherein fuel flow through the primary fuel outlet causes fuel flow through the secondary fuel outlet. The mass flow rate of fuel through the fuel drain is restricted so that the allowable mass flow rate of fuel through the secondary fuel outlet is configured to be greater than the allowable mass flow rate of fuel through the fuel drain in the baffle.
