The main objective of this work was to understand the detailed operation of the Full Authority Digital Engine Control (FADEC), in order to disseminate this knowledge to the aeronautical community. The research is characterized as exploratory, with bibliographic and documentary procedure through books, articles and technical manuals. As for the nature of the research, it was based on the quantitative approach. The analysis of the data was done through graphs and tables, analyzed according to the theoretical basis. At the end of the research, it is concluded that the digital system allows a better use of the available power in the aircraft engines, through a precise dosage of the fuel. And that, in addition to calculating the exact amount of fuel to be introduced in the combustion chamber, manages other functions such as: presentation of data to the crew through the Vehicle and Engine Multifunction Display (VEMD), automatic starting system, limits control of the primary engine parameters, Engine Power Check (EPC), calculation of turbine cycles, gas turbine wear control etc. Thus, in the command of the Airbus H125 and H130 helicopters equipped with this kind of dosage, it is up to the pilot to maneuver them in the skies. However, the fuel control will always be electronic and performed automatically. A computerized calculation that reduces crew workload, increasing the flight safety.
