Transforming UK Airspace: A New Era for Drones and Aviation with NATS OpenAir

By Richard Ryan, Drone Lawyer

The skies over the UK are on the verge of a transformative shift, thanks to the ambitious NATS OpenAir initiative. Designed to integrate drones and advanced air mobility (eVTOLs) into shared airspace alongside traditional aircraft, the proposal promises innovation, efficiency, and safety. But as with any grand vision, the devil is in the detail.
Here’s an in-depth look at what the OpenAir initiative is getting right, where there are gaps, and how it can evolve to meet the needs of all airspace users.
________________________________________
1. Prioritising Data Privacy and Ownership

One of the most valuable resources in aviation is data. For drone operators, who depend on real-time information about flight paths, weather, and airspace restrictions, access to reliable data is critical. However, the OpenAir proposal is light on specifics about who owns the data and how privacy will be protected.
Without clear protections, drone operators might worry about their data being exploited—whether commercially or in ways that jeopardise their competitive edge.

The Fix:
OpenAir must adopt a clear data privacy framework. Operators should retain ownership of their data, with mandatory anonymisation for any information shared beyond essential safety and operational use. Only the bare minimum of data required for regulatory compliance should be shared, and stringent safeguards must prevent its misuse.

2. Keeping the Playing Field Fair

OpenAir is envisioned as a centralised hub for managing UK airspace, which sounds great—until you consider the potential impact on smaller players. Consolidating services under one entity like OpenAir might inadvertently stifle competition among Uncrewed Traffic Management Service Providers (UTMSPs).

The Fix:
To level the playing field, OpenAir should adopt open standards that allow seamless third-party integration. Smaller UTMSPs must be supported, not sidelined. Clear rules around equitable access to data and services will ensure innovation thrives without creating monopolies.

3. Setting Realistic Timelines

Integrating drones and eVTOLs into shared airspace isn’t a simple task. OpenAir’s proposed rollout timeline—beginning pilots in 2025 and achieving full deployment by 2028—might be overly ambitious, especially given the complexity of regulatory approvals and the need for robust infrastructure.

The Fix:
A phased approach with realistic benchmarks is the way forward. OpenAir should focus on pilot projects in key areas where demand is highest (e.g., urban delivery drones or emergency medical services). This would provide valuable data to refine the system while reducing the risk of rushed implementation.

4. Managing Costs for Drone Operators

OpenAir’s “user pays” principle makes sense in theory—those who use the airspace services should cover the costs. But smaller operators, such as local delivery drone companies, could be disproportionately affected by high fees, potentially pricing them out of the market.

The Fix:
Introduce tiered pricing. Small operators should pay less, at least during the initial phases. Alternatively, subsidies or credits could be offered to early adopters, ensuring fair access while fostering adoption across the board.

5. Addressing Legal Grey Areas

OpenAir aligns with the UK’s Airspace Modernisation Strategy, but its relationship with existing regulations like CAP 722 (which governs drone operations) needs to be crystal clear. Ambiguities in compliance requirements could delay approvals or lead to legal disputes.
Similarly, liability concerns loom large. If there’s a system outage or data error, who’s responsible for the fallout? Drone operators? OpenAir? The CAA? NATS? DfT?

The Fix:
OpenAir must explicitly state how its services integrate with CAP 722, especially for critical areas like Beyond Visual Line of Sight (BVLOS) operations. As for liability, service agreements must clearly define responsibilities, ensuring all parties—operators, OpenAir, and regulators—understand their obligations.
________________________________________
6. Building Trust Through Transparency

For OpenAir to succeed, trust is key. Stakeholders—including drone operators, regulators, and public service agencies—must feel confident in the system’s fairness and security.

The Fix:
Establish an independent advisory board with representatives from all key groups, including Blakiston’s Chambers! This board would oversee the rollout of OpenAir, ensuring transparency and accountability. Regular public updates and feedback sessions would further build trust and address concerns early.
________________________________________
7. Looking to the Future

The potential of OpenAir is undeniable. By creating a unified platform for managing UK airspace, it could unlock opportunities ranging from efficient logistics to life-saving medical deliveries. But to truly succeed, OpenAir must:
1. Prioritise data privacy and ownership.
2. Ensure fair competition for all service providers.
3. Adopt a phased, realistic rollout plan.
4. Keep costs manageable for smaller operators.
5. Align with existing regulations like CAP 722.
6. Address liability concerns upfront.
7. Foster trust through transparency and stakeholder engagement.

The skies above us are changing, and with thoughtful planning, OpenAir could make the UK a global leader in integrated airspace management. But to get there, it must balance ambition with practicality, ensuring the system works for everyone—from global eVTOL operators to local delivery drones.

8. Comparison with EASA PDRA03 and Lessons for the UK
Comparing the CAA’s position with the European Union Aviation Safety Agency’s (EASA) Pre-Defined Risk Assessment number 03 (PDRA03) reveals both opportunities and challenges for UK drone regulation. EASA’s PDRA03 offers a structured, risk-based framework that allows operators to self-declare compliance with specific conditions, reducing administrative burdens and accelerating operational approvals. This approach supports drone operators by providing clear guidelines while fostering innovation through flexibility in operations such as autonomous flights, multi-UAV control, and operations beyond visual line of sight (BVLOS) under certain conditions. In contrast, the CAA’s policy concept imposes more prescriptive requirements, such as mandatory NOTAM submissions for each operation and specific technical equipment like ADS-B transceivers, which may be unnecessary and bureaucratic for certain low-risk operations. The UK drone industry could benefit from adopting elements of the EASA PDRA03 by implementing a more proportionate, risk-based regulatory framework that emphasises operator declarations and standardised procedures. This would streamline the approval process, reduce administrative overheads, and encourage innovation while maintaining safety. Learning from the EU’s experience, the CAA can enhance its policies to better support the growth of the UK drone industry by embracing flexibility, reducing unnecessary bureaucratic requirements, and aligning more closely with international best practices.
