The invention of the APU on the basis of that, the aircraft auxiliary power unit monitoring method of the turbine efficiency is obtained the APU message at a plurality time point within a period of time, and the APU message relating to the monitoring method and apparatus of the aircraft auxiliary power unit turbine efficiency the time obtaining the start-up parameters, the start-up parameters are calculated a turbine rotational speed ratio NPA when at least the peak value comprises the EGT rotational speed, the exhaust gas temperature during APU start-up of the rotational speed during APU normal operation reaches a peak value, and calculating the average value in the NPA, and it is determined that the performance of the APU turbine efficiency based on the mean value NPA facing ballast groups, decline or failure.
