  • EPCOR knows how important it is to have a stable operating APU on wing. The system Prognos for APU allows EPCOR to predict maintenance and prevent unnecessary shop visits and delays. It is a high value solution for the APU maintenance market, designed and built by EPCOR. Prognos for APU helps airlines maintain maximum control over their APU assets, keeping them operating for as long as possible with minimal effort.
  • The system is based on big data, which allows the APU to be monitored. At each airport stopover, the data is sent to a central computer. Because of our extensive experience, we can inform you about your APU and even predict when certain parts will break down and at which levels. We perform the required maintenance well before this happens.



Prognos for APU is available for every EPCOR customer. How? Ask your own Customer Support Manager and he or she will inform you.

If you are not yet a customer of EPCOR but interested in Prognos for APU? Contact our sales department for more info. 




EPCOR has seven types of APUs, which are available for both short-term and long-term leasing. That means that our clients do not have to halt their operations when their APU is being repaired or in maintenance – they can continue flying with an EPCOR APU. In addition to our own APUs, we have cooperation agreements with our partners to ensure full availability of APUs for our clients. It also means that we have different types of APU on hand at different locations around the world.
