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”. More...

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.

This Essential Operational Change covers both changes to operations at Airports and TMA airspace that allow maintenance of operational capacity under limiting conditions and changes that allow increase in operational capacity during normal Operations. This includes enhancements to planning and execution of operations at/around the airport like traffic sequencing, reduced separation, reduced and more predictable runway occupancy time and enhanced management of taxiway throughput, for both arrivals and departures. This EOC addresses as well the needed coordination with TMA operations where aircraft sequencing towards the runway begins and even further with extended arrival management (E-AMAN) in en-route airspace. It also includes solutions that enhance the safety of operations and addresses as well the reduction of the environmental impact at or near airports. Enhanced navigation and accuracy in low visibility conditions on the airport surface needs to be made possible by the introduction of new airborne and CNS capabilities.
