In 2017, the International Air Transport Association (IATA) projected a near doubling of the number of passengers by 2036, from $ 4 billion to $ 7.8 billion.
To cope with this sustained growth, “over the next 10 years, nearly 10,000 aircraft must be delivered to airlines, as much as in Airbus’ 42-year history”, said Marwan Lahoud, President of GIFAS, the French Aerospace Industries Group, also in 2017. The current health crisis has certainly introduced a parenthesis, but we can bet that it should not undermine this underlying trend in the long term.


In any event, a strong rationalization of costs remains a key concern. For system designers, suppliers and manufacturers, it implies to think about new architectures and technological solutions enabling to reduce aircraft weight, to increase their autonomy, all the while reducing downtime required for maintenance anticipating it as much as possible through predictive maintenance systems.

Furthermore, the aircraft is now fully connected:

  • In the cockpit, pilots can benefit from applications that allow them to optimize their flight plan in real time.
  • In the cabin, the airlines are offering an increasingly personalized experience to their passengers, including Internet connections on board.

Embedded systems are at the heart of all these developments.


For more than 20 years, ELSYS America has been assisting system integrators, equipment manufacturers and suppliers in the design and development of customized aeronautical embedded systems. Our intervention modes include technical assistance / work packages / dedicated development centers in the following areas:

  • Design of embedded electronic systems – intelligent sensors and actuators, calculators located close to the plane’s heart components, communication networks…
  • Development of embedded software – smart sensors, processing software, simulation software, communication networks…

We carry out our ISO 9001v2015 development cycles in strict compliance with aeronautical standards, mainly DO-178B (Regulations for Software Development in the Aerospace Sector), DO-254 (Electronic Systems Design Insurance Guide for Airbone) and DO-160G (Environmental conditions and test procedures for air equipment), with different levels of criticality (DAL A to E).

We are extending this offer in aeronautical embedded systems design to mechanical engineering thanks to our sister company MECAGINE.

Finally, with our other sister company AViSTO, we are able to design new digital applications, for example in the areas of connectivity, big data, artificial intelligence or cyber security.

The vision of our founders was to create ELSYS America and build around it a group of specialized and complementary companies.

A group in permanent development, thanks to the new projects and the daily interactions between its various stakeholders.

A group which is a great place to work, consisting of companies in which the engineers thrive and continue to progress, serving their customers.

20 years later, ADVANS Group has become a reality. It is composed of 3 companies, their international subsidiaries, and a whole group of stakeholders with whom we have established partnerships (start-ups, solution providers, research institutes, laboratories, universities, etc.).

Thus, our engineers are placed at the heart of a rich, innovative, and exciting ecosystem, in which it is great to work, and whose pivotal link is the passion of its members for technology. Without passion, is it possible to strive for excellence?
