APU Predictive maintenance solutions

331-500 APU is a very intelligent engine. Each cycle it generates an advanced performance data report. Prognos for APU, our state of the art fleet management platform uses these data sets to predicts when your APU is about to fail.

Data alone is not sufficient, our APU engineers are constantly monitoring the APU performance of about 1000 aircraft. How we do? Check out this video.
