1. An aircraft fuel tank inerting system, comprising:
a left wing fuel tank;
a right wing fuel tank;
a left surge tank;
a right surge tank;
an inert air assembly;
a first fluid valve connected to at least one of the left wing fuel tank and the left surge tank;
a second fluid valve connected to at least one of the right wing fuel tank and the right surge tank; and
an electronic control unit configured to:
control a position of the first fluid valve to provide inert air from the inert air assembly to at least one of the left wing fuel tank and the right wing fuel tank; and
control a position of the second fluid valve to provide inert air from the inert air assembly to at least one of the left surge tank and the right surge tank, wherein in at least one condition, the position of the second fluid valve is the same as the position of the first fluid valve.
