EMA4FLIGHT and VALEMA are two linked projects for developing Electronic Control Units and Electromechanical Actuators for flight control systems.

The goal of EMA4FLIGHT  is to design and develop optimised and reliable electromechanical actuators, as well as their Electronic Control Units for controlling flap surfaces. The EMA4FLIGHT project contributes to current research for a More-Electric Aircraft (MEA).



In the case of actuators used for aircraft surfaces such as flaps, the main advantages are: reduced weight and maintenance, eliminating pipe vibration problems, increased system reliability and performance, and reduced loss of pressure thanks to the absence of valves. EMA4FLIGHT has made an additional effort in the development of ECUs by only using simple components according to regulation DO-254, which simplifies the rating procedure of the units.

The project VALEMA is closely linked to EMA4FLIGHT, as the former’s goal is to manufacture and validate the EMA + ECU subsystem, so it may be included in the FTB2 demonstrator for in-flight validation.


VALEMA (Validation tests of electromechanical actuators and their dedicated control units at the TRL 6 level) has two defined targets:

  • Manufacturing EMA (Electro-Mechanical Actuators) and ECU, designed and developed according to the specifications of JTI-CS2-2016-CFP03-SYS-02-14.
  • Conducting HW and SW quality tests of the Control Units (ECU) in order to obtain flight permission in the Regional Aircraft FTB2 demonstrator.

One of the project’s key goals is to achieve a TRL of 6 and to fulfil the safety requirements of the hardware regulation RTCA/DO-254 and the environmental regulation RTCA DO-160.

These projects have been funded by the Horizon 2020 research and innovation programme of the European Union.
