With the drive of new technologies, going further every day in terms of technical specifications and demonstrating that they are capable to replace current and older technologies, the aeronautical world is in a process of change towards a more technologically advanced framework. The introduction of the programmes SESAR in Europe and NextGen in the USA is the response to the needs of the industry for a more sustainable and up to date structure. All these changes involve an important technical development which consequently varies the way aircraft manufacturers work and how new aircraft are designed, but it also affects planes currently flying. In this line, ATR is looking to answer to both the needs of the market, but also regulatory requirements, for which the proposal for this internship has been made. The objective will eventually be to guide the product towards the current and future requirements as an exercise for the future. For the purpose, together with the certification office, the European regulatory framework affecting Air Traffic Management has been studied, which from a manufacturers point of view mainly affects Communication, Navigation and Surveillance systems. With the knowledge of the regulations, it will be possible to position ATR aircraft in current regulations, but it will also be possible to orientate future actions in system design towards the goals of the aforementioned necessities. Speaking more specifically, the latest regulations that have arisen due to the development of SESAR have been studied, which mainly affect digital communications, performance based navigation (PBN) based on GNSS and the relay of extended surveillance data using new transponder specifications. The main objective of the work is to serve as future guidance when developing new products for ATR, but also to assess the current situation of the ATM framework.
