Summary:5 The present application discloses a method for detecting performance of an APU,comprising: obtaining EGT (Exhaust Gas Temperature), LCIT (Load Compressor Inlet Temperature), STA (Starting Time), TSR and PT, comparing respectively a difference of EGT and LCIT (i.e., EGT-LCIT), STA, TSR and PT with respective threshold value; assigning a weights to comparison results between the EGT-LCIT, STA, TSR and PT and the respective10 threshold value; and determining the performance of the APU based on the comparison results considering the weight between the EGT-LCIT, STA, TSR and PT and the respective threshold value.15 Figure 6
