The aeronautics industry is at the forefront of innovation, pushing the boundaries of what is possible in the realm of air travel.

Driven by the need for faster, more efficient, and more comfortable flight, challenged by environmental constraints, aeronautics engineers are continuously exploring new technologies and materials to create the best possible product. From advanced materials and engines to cutting-edge avionics and navigation systems, the aeronautics industry is constantly striving to make air travel safer, more convenient and enjoyable. 

Decarbonizing the future of aviation

The aeronautics industry has come under scrutiny in recent years for its CO2 emissions. Current projections estimate that demand for air transport in 2050 could exceed 10 billion passengers. To meet this demand in a sustainable fashion, the industry is making considerable efforts to move towards decarbonization, with a commitment to net-zero emissions by 2050. Hydrogen-powered aircraft, electrification and new fuels are just some of the innovative technologies that are expected to make this possible, together with design and engineering innovations and the improved industrial management of development cycles.
