An aircraft fuel system monitor 3 has a processor 30 which generates a prediction 36 of the quantity of fuel present on the aircraft based on first information 31 indicating aircraft fuel parameters; second information 32 about the aircrafts fuel system configuration; and one or both of third information 33 indicating aircraft orientation; and/or fourth information 34 indicating non-fuel related aircraft systems states. The first information may be a physical attribute measurement of fuel density, temperature, permittivity, and/or height/level. The second information may be details of fuel-: tank geometry; system physical arrangement; system component status. The third information may be values of attitude, pitch, roll, acceleration, altitude, centre of gravity, and/or speed. The fourth information may relate to operational status of flight control, landing gear, cabin environment, navigation, and/or powerplant systems. Fifth information 35 indicating fuel quantity present in the aircraft may be received by the processor, this compared with the prediction to detect fuel system faults. Non-fuel related system faults may also be detected by the processor based on some, or all, of the received information. The processor may use a supervised machine learning algorithm to generate the prediction, trained using information from a historical time period.
