From 2000 to today, air traffic due to civil aviation has seen an increase of 2.4 times, and with a forecast of doubling further in 15 years. The growth of the aerospace industry leads to raise up standards and considers cost effective solution. Electromechanical actuators in the last century have a high growth rate. These parts will become essential for primary and secondary flight controls, this transition leads to higher quality standards and the development of algorithms that can predict their operation. Through prognostics algorithms it will be possible to evaluate in real time the behavior of the aircraft and predict failures.
