Keeping aircraft safely separated is one of, if not, the core function of air traffic management today. But as more aircraft become more diverse and numerous, the airspace becomes more complex to manage. The project aims to advance automation technology solutions and procedures that will help controllers to handle the traffic in a smooth and efficient way.

Specifically the project is addressing the following SESAR solutions:

Solution name

Solution number



Collaborative control

PJ.10-W2-73 CC

Controllers coordinate traffic at sector boundaries using voice or electronic dialogue to maintain safe separation between airspace users. Using the SESAR solution of collaborative control, controllers can issue instructions to aircraft outside their sector to support more efficient flight profiles throughout the collaborative area without specific coordination when there is no affecting traffic.


Flight centric air traffic control

PJ.10-W2-73 FCA

European airspace is divided into flight information regions, which are subdivided into sectors to provide safe separation services for aircraft travelling through the airspace.  Changing this to a flight-centric structure without reference to geographical sectors opens up the opportunity to distribute the traffic more evenly, and to avoid lost productivity in under-loaded sectors.


Increased flexibility in ATCO validations

PJ.10-W2-73 IFAV

Air traffic controllers receive detailed to acquire a specific qualification. They also receive sector validations, which permit them to control defined volumes of airspace. SESAR is developing non-geographical sector qualifications to remove current constraints and move towards a more flexible approach where environmental knowledge and other information needs are supported by systems, procedures, airspace, training and regulatory adaptations.


Delegation of ATM services provision amongst ATSUs


The rigid nature of Europe’s airspace infrastructure makes it difficult to delegate airspace amongst air traffic service units based on traffic demand or organisational needs such as day/night operations.
SESAR is exploring the delegation of airspace in expected and planned situations - such as peak traffic load at fixed times - as well as unscheduled occurrences for example in cases of service degradation or failure.


Attention guidance

PJ.10-W2-96 AG

Situational awareness and attention are two important skills that controllers need to keep at a high level when controlling aircraft at a radar screen.  SESAR research is examining salient visual stimuli to guide the operator’s attention to potential hotspot or conflict areas on the radar screen if the event goes unnoticed by the controller for a given time frame. The attention guidance solution aims to guide the controller’s attention through the use of an eye tracker system and intelligently prioritise the events shown.


Automatic speech recognition

PJ.10-W2-96 ASR

Controllers rely on their workstation to provide the support tools to manage air traffic and minimise workload in dense or complex airspace. Voice communications are central to controller activity yet risk being misheard or subject to congestion, prompting research into automatic speech recognition (ASR). This solution covers three aspects of ASR with the aim of reducing workload and improving flight efficiency. The technology considers text predictions based on surveillance data; creating ATM commands based on existing ATC concepts; and a combination of both to provide further applications for the controller working position (CWP).


The project is conducting wide-ranging validation exercises on the solutions, bringing controllers onboard to test and provide feedback on their usability. Ultimately, these solutions are expected to bring benefits to the ATM network in the following key areas:

  • Safety
  • Capacity
  • Efficiency
  • Flexibility
  • Cost-Efficiency
