What is Data4Safety?

Data4Safety (D4S) is a voluntary partnership programme that aims to identify systemic risks at EU level as well as their mitigations. The program ambitions to significantly increase the safety intelligence capacity in Europe to know where to look, see things coming and act! 

This is done by organising a massive collection of aviation data and, equally important, organising the analytical capacity amongst all European aviation safety partners. It is a collaborative programme like nothing before, enabling the EU Member States and Industry to join forces and team up to work together at a scale never achieved before in Europe.

How does Data4Safety function?

D4S collects inputs from across the aviation system. This includes safety reports, flight data from airlines, traffic data from the ATM system plus weather data and anything else that adds value to our understanding of the aviation landscape.

The massive collection and processing of these data sources is made possible by the advent of the Big Data and Data Science technologies that the D4S Programme fully leverages in a central Big Data Platform for Aviation in Europe.

The aviation data gathered on the Big Data platform is then utilized by the experts from the Member States and the Industry who can join forces and team up with the data scientists on the D4S Collaborative Analysis Platform. 

From this process, there are outputs that benefit both the wider European Aviation System and also the individual organisations that are involved in D4S. The result includes metrics, directed studies on particular safety topics, blind benchmarking and vulnerability discovery (the ability to find the new and novel things that might cause a risk).


The key principles of Data4Safety

D4S has the principle of Just Culture at its heart, with a strong governance to ensure Data Protection for all organisations involved so that them and their staff are fully protected. The programme allows to better identify where risks are (safety issue identification), determine the nature of these risks (risk assessment) and verify if the safety actions are delivering the needed level of safety (performance measurement). It aims to develop the capability to discover vulnerabilities in the system across terabytes of data.

The trust environment and data protection

The Big Data platform is managed by a dedicated third-party organisation: the Data Processing and Protecting Organisation (DPPO). Under the supervision of a Supervisory Panel (composed of programme members), the DPPO will be responsible for the definition and implementation of a Big Data architecture adapted to the objectives of the Data4Safety Programme. In addition, the DPPO is responsible for the collection, protection and processing of the main safety data sources that are currently scattered within the Aviation System and that will be considered relevant for the D4S programme.

The D4S data protection model ensures authority and control over the management of all data in the D4S data lake according to the programme principles, while taking legal requirements into account. The D4S Data Governance is the reference set of written procedures and protocols developed collaboratively by the Programme Members and validated by the Steering Board to frame and control all operations on the data collected and processed by the Programme.

Which organisations and airlines are already involved in Data4Safety?

D4S is led by EASA, co-funded by DG MOVE and powered by its Members. Below you can see the Founding Members that enabled the initial Proof of Concept phase. The airlines and other organisations involved have supported the programme by providing data and expertise. As the new development phase launches in late 2022, will your organisation be the next to join this exciting programme?


An inclusive long-term programme?

As we look to the future, D4S will evolve over time into a fully inclusive, collaborative programme that will draw its membership from across the European Aviation Community. It is envisaged that the programme will grow to include not just airlines or aircraft manufacturers, but also airports, ANSPs, engine manufacturers, business jets, ground handlers, maintenance organisations and many, many more. 

Data4Safety Roadmap – What happens when?

The D4S project began with a feasibility study in 2015 and moved into proof of concept from 2017 to 2022. Now the project moves into the development phase from mid 2022 to 2025. This will bring an expansion in the members of the project. More Member States and airlines will join first, along with the first ANSPs and then airports to progressively embrace the complete European Aviation Sector by the end of the Development phase.

The project will also extend to cover sustainable available and also cyber/ security aspects having an impact on aviation safety. 


Want to be involved – who to contact for more information?

Now that you have learned more about D4S and the exciting possibilities it brings for the European Aviation industry, you are hopefully interested to learn more and even become part of the project with your own organisation. 

EASA is now seeking additional membership from airlines, National Aviation Authorities and ANSPs across Europe. For more information please contact Data4Safety [at]
