Abstract: Fuel systems, apparatus and associated methods for preventing or hindering unwanted fuel transfer between fuel tanks of aircraft are described. An exemplary apparatus comprises a conduit portion disposed inside a fuel tank for receiving fuel in the first fuel tank. The conduit portion includes an orifice through a wall of the conduit. The orifice permits venting an interior of the conduit portion to an interior of the fuel tank to prevent unwanted fuel transfer due to siphoning. A deflector is disposed and configured to deflect a stream of fuel discharged from the orifice during fuel transfer.

Abstract: A method of and a system for detecting a fuel leak in an aircraft, the aircraft comprising a first engine and a second engine. The method comprises upon determining that the aircraft has reached a first mode of operation: acquiring a first baseline fuel flow of the first engine; acquiring a second baseline fuel flow of the second engine. The method further comprises monitoring a first current fuel flow measured at the first engine and a second current fuel flow measured at the second engine; and triggering a fuel leak detection based on an analysis of the first baseline fuel flow, the first current fuel flow, the second baseline fuel flow and the second current fuel flow.
