The invention relates to the field of airborne air conditioner performance monitoring, and discloses an air conditioner system performance judgment method based on remote monitoring, which comprises the following steps: S1, collecting A21th message data and A24th message data through a hardware FDIMU; s2, performing data decoding, regression calculation, mean variance calculation, left and right air conditioner data difference calculation and normalization processing on the A21th message data and the A24th message data, and calculating trend analysis of each parameter and +/-2sigma external data calibration; s3, establishing an important parameter evaluation model based on the steady-state core characterization parameter data of the air conditioner and an AHP (analytic hierarchy process); and S4, a PNN probability neural network is applied to classified recognition of the normal operation mode and different failure modes of the air conditioner based on the Bayesian criterion, and the failure sub-components of
