The UK Civil Aviation Authority (CAA) has released safety analysis research in collaboration with WMG, University of Warwick, to outline how eVTOL aircraft could be safely integrated into UK airspace with 50 high-priority areas of development.
The study, which lasted 18 months and was funded by the Department for Transport, aimed to identify potential hazards and safety gaps within aircraft, software, hardware, and human interactions. The proceedings included workshops, technical meetings with stakeholders such as Bristow and NATS, and research at the British Grand Prix at Silverstone due to the event’s high volume of helicopter (and potentially eVTOL in the future) operations.
The key outputs of the report were as follows:
- Airspace integration challenges: Air Navigation Service Providers should implement mechanisms to detect and alert controllers/service providers to deviations in aircraft performance (e.g., altitude, speed, trajectory) from expected parameters.
- Vertiport operational standards: The criticality of energy management requires Ground Services to use advanced real-time sensors to provide continuous feedback on landing conditions.
- Automation and simulation oversight: There are currently no mandated protocols for using automation and simulation tools to detect performance deviations or predict flight path conflicts.
“With eVTOL aircraft expected to enter UK airspace within the next few years, proactive planning and coordination are essential to ensure their safe, responsible and seamless integration,” said Rick Newson, Co-Chair of the eVTOL Safety Leadership Group, at the UK CAA. “This research provides valuable insights into the complex challenges and potential risks ahead. The results will feed into our ongoing regulatory development to enable innovation while maintaining the highest safety standards.”
“For any technology, ensuring its safety is an absolute requirement for it to succeed commercially,” commented Professor Siddartha Khastgir, Head of Safe Autonomy at WMG, University of Warwick. “And for emerging technologies like eVTOLs, a systems thinking approach to safety is necessary to understand the multiple interactions between the stakeholders. Underpinned by an open and transparent discussion, we commend and are grateful for this sector’s willingness to participate in this study, enabling them to identify and prepare for safety challenges for future eVTOL operations.”
“This is an extremely valuable piece of work which proactively identifies potential risks and enables them to be mitigated effectively. With the emergence of new technologies, it is essential to pragmatically manage safety from the start, and this project is an important part of that process,” added Simon Meakins, Co-Chair of the eVTOL Safety Leadership Group and Director of Advanced Air Mobility at Bristow Group. “I thank the entire team… engaged in the project for their dedication.”
