Modernising Air Traffic Management (ATM) is crucial for the sustainability of European aviation and the forecasted increase in air traffic by 2035. The Single European Sky’s ATM Research project "SESAR" is one of the most ambitious modernisation projects launched by the European Union contributing to the implementation of the Single European Sky. SESAR’s goal is to define, develop and deploy the technological solutions needed to increase the performance of Europe’s ATM system.

The European ATM Master Plan is the roadmap for driving the European ATM modernisation programme, executed by the SESAR Joint Undertaking (SJU). It sets out the necessary steps involved for the development and deployment of SESAR Solutions with technologies and operational procedures, linking them to the Single European Sky performance objectives and ensuring global interoperability and consistency with the ICAO Global Air Navigation Plan.

The SESAR Joint Undertaking (SJU) is responsible for the modernisation of the European ATM system by coordinating and concentrating all relevant research and development efforts in the EU. It is a public-private partnership (PPP) between the main public stakeholders (European Union - represented by the European Commission - and Eurocontrol) and industrial European ATM stakeholders.
