Essential Operational Changes

This 2020 edition of the European ATM Master Plan introduces nine new Essential Operational Changes top-down as nine essential “game changers”. They are shown here and they are triggering structural evolutions of the European ATM, that are required to deliver the SESAR vision, up to and including its phase C and the “digital European sky” enabling the delivery of the Single European Sky’s objective to implement “more sustainable and better performing aviation”.

The EOCs are not independent from each other. In particular, some of them are closely linked to delivering the en-route performance and have been driving the definition of the target architecture, while others bring the essential changes in the other parts of the system.

For learning more about the new Essential Operational Changes, the Chapter 4.2 of the European ATM Master Plan document refers.

Each EOC is supported by SESAR Deployment Scenarios containing solutions contributing to their achievement.

Select from the drop-down menu the Essential Operational Change. Hovering with the mouse over a Deployment Scenario will display further details on it, hovering over a timeline bar will show the associated dates.

The ATM collaborative network enables all relevant stakeholders to participate in collaborative decision making processes in a transparent framework and to negotiate their preferences and reach agreements that not only benefit one but all the stakeholders involved, thus contributing to the performance of the entire network. The collaborative network operations plan (NOP) will provide, in a continuum from planning including execution, a real-time visualisation of the evolving network planning environment, leading to network stability, increased capacity and increased efficiency. Further evolutions of demand and capacity balancing (DCB) tools and enhancements of ATFCM process via collaborative network operational planning are needed not only to enhance the network performance but also to allow the integration of ATFCM and ATC planning function. The integrated local DCB processes intend to improve the situational awareness by the seamless integration of local network management with extended ATC planning and arrival management activities. The network prediction and performance processes intend to provide increased efficiency through assessment of performance of network operations with stakeholders able to evaluate the impact of their intentions and decisions. The collaboration among stakeholders, in real time, is improved by the extended airport integration with ATM network planning, multi slot swapping and user driven prioritisation process, allowing airspace users to recommend a priority order request for flights affected by delays and to share preferences with other ATM stakeholders, in capacity-constrained situations, but available as well in non-constrained situations, during planning and execution phase, facilitating Airspace Users flexibility for attending unexpected business needs. The integration of airport and network targets the timely exchange of relevant airport and network information, resulting in a common situational awareness and improving network and airport planning activities as well as overall operational performance. The collaborative airport and network processes are expected to deliver arrival and departure predictability for both the airport and the network in nominal and non-nominal conditions. The infrastructure component of ATM collaborative network needs to be based on the implementation of a service delivery infrastructure, by the provision of accurate information using common standards. Global interoperability and standardisation are essential and this EOC is expected to be an important driver for new and updated standards. It should be based on service oriented architecture driven by analysis of business processes and needs. The ATRM collaborative network is developed, packaged and implemented as a suite of interoperable services that can be used in a flexible way within multiple systems from several business domains as well as open and standardised mainstream technologies.
