The European ATM (eATM) Portal provides an integrated view of the European ATM System. It is the home of the electronic web-based platform providing access to all information composing the three levels of the European ATM Master Plan (the Master Plan) outlining the essential operational and technological changes as integrated within the European ATM Architecture. These changes provide the SESAR contribution to the Single European Sky performance objectives.
The three levels of the Master Plan are:
- level 1: executive view;
- level 2: planning and architecture view;
- level 3: implementation view.
The Public environment of the European ATM Portal gives access to Master Plan Level 1, 2 and 3. The working environment contains the public environment completed with the European ATM architecture. It describes the nature and impact of the changes modelled according to the European ATM architecture framework (EATMA).
