Over the years, and the evolution of technology, turbine engines have become increasingly complex. With the growth of their complexity, have increased the loads of work related to maintenance and identification of faults that may have an impact on security.
The monitoring (observation) of the state of health of the engine and its performance is given in modern engines, to the Engine / Health Monitoring System (EMS / HMS), consisting of an integrated package of equipment that acquire data from the engine, record them, develop them, and transmit the results to staff and ground stations.

Avio has a good experience in Health Monitoring, experience gained through participation in major national and international programs. RB199, and T700 are EJ200 engines have different ways of interpreting the Health Monitoring (or HUMS, Health and Usage Monitoring System), both for the different historical period in which they were developed and for the type of engine and specific application.

Avio has designed the system Ma.Re. (Maintenance Recorder) for RB199, consisting of a network of ground stations that analyze the data engine during the flight and calculate the remaining life of engine components and its performance. It is a first system of Condition Based Maintenance, which received certification in 2008 for Armaereo.
The program EJ200, is significant activity in the development of the functions of Lifing (which continues the experience of Ma.Re.) and Oil Debris Monitoring, a important trend that is also on base of industrial research to monitoring gearbox.
