The role of Air Traffic Control in future airspace

Airspace is a critical part of the UK’s national infrastructure. Modernising it is essential if the aviation sector is to meet future aviation demand. Airspace modernisation will help deliver cleaner, quieter and smarter flights, while reducing complexity and improving capacity across the wider network. The drive for airspace modernisation means it is more than an aviation project; it’s a national priority that’s been backed by government policy since 2018.  

The human factor in airspace transformation

Air Traffic Controllers, or ATCOs, are closely involved in every stage of airspace change. Their operational insight is critical from the outset, highlighting risks and challenges early in the process. They then work alongside airspace modernisation teams to develop practical, innovative designs grounded in both data and real-world controlling experience. ATCO input can range from small prototyping to large-scale validation activities. ATCOs offer an understanding of the end user impact throughout each step of an airspace change.

Controllers also provide their services during simulation activities from early development. In these early stages, they use their skills to test design concepts. Later in the process, they help train their operational colleagues on the final design ahead of implementation. As subject experts, ATCOs also play a crucial role in engagement, offering expertise and answering questions directly from their experience, helping to build trust across stakeholders from aviation industry partners to local community representatives. As well as active ATCOs working on projects, many members of the wider airspace change team are also licensed controllers, enabling an additional level of knowledge and confidence to the development and validation of proposals.

In this video, Toby Reed gave us insight into how ATCOs are involved in projects through the entire process. Toby is also a qualified Air Traffic Controller currently working on Oceanic operations in our Prestwick centre.  

The technology driving airspace change

Our design team leverages advanced software and tools, including DesignAir, which allows us to redesign, compare and test airspace designs. By incorporating real operational data and scenarios, the software allows us to assess multiple factors simultaneously, including route efficiency, emissions impact and safety requirements.

This approach also enables us to predict and mitigate potential risks early, reinforcing our role as a trusted custodian of the skies. But while access to world-leading technology is important, strong and consistent ATC involvement remains essential to ensure the airspace we design is both safe and effective for the future.

Safety beyond technology

Even with the introduction of modern technologies such as Performance Based Navigation, ATCO monitoring and intervention remains essential to manage unexpected situations and maintain a safe and resilient operation. As well as offering expertise throughout the design phase, ATCOs participate in the generation of safe and effective procedures, including supporting relevant safety assurance work and on-going training. While controllers are involved in simulation activities throughout the change process, formal training begins for the wider team closer to deployment when the design is fully mature. Depending on the complexity of the change, training can be through digital e-learning through to a blended approach including simulation sessions and assessment.

As the UK’s airspace continues to evolve, the role of Air Traffic Control will remain central to making change work in practice. From helping to design new routes to ensuring they are safe, effective and understood by those who use them, controllers bring the expertise that turns concepts into reality. Together with new technology, that human insight and expertise will be essential in creating a future airspace system that is ready for the demands of tomorrow.
