The basic faults detection logic of fuel flow metering valve can not detect all the faults. It may cause un-commanded in-flight shut-down (IFSD) on the aero-engine and threat the flight safety. The operation principle of fuel flow metering valve is introduced in this paper. The basic faults detection logic is given. Two IFSD examples are presented. To reduce the un-commanded IFSD, faults detection logic updating is discussed. It can be used to design the new control software of the aero-engine and improve the aero-engine’s reliability.
