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.

From the Battlefield to the Courtroom: Building a Resilient and Modern Drone Fleet

By Richard Ryan, drone lawyer

Recent announcements from John Healey, the UK Secretary of State for Defence, regarding cuts to the MOD’s fleets of ships, drones, and helicopters have sparked widespread debate. While some argue that these reductions undermine the UK’s defence capabilities, others see an opportunity to address long-standing issues with procurement inefficiencies and embrace more agile, cost-effective solutions.

As a drone lawyer with extensive experience in regulatory and operational challenges, I see this as a moment to recalibrate not just how we deploy drones but also how we legally and operationally future proof them. Resilience, as Healey noted, must be a watchword—not only on the battlefield but also in the courtroom.

Modern Drone Fleets: More Than Just Technology

The blog post raises an essential question: What are the key requirements for a modern drone fleet? While operational capabilities like ISTAR (Intelligence, Surveillance, Target Acquisition, and Reconnaissance) and resilience to environmental threats are crucial, I believe the answer must also encompass the legal frameworks underpinning these fleets. Without addressing these considerations, even the most advanced systems could falter under regulatory scrutiny or operational restrictions.

Here are four key areas where legal considerations play a pivotal role in building a resilient drone fleet:
________________________________________
1. Legal and Regulatory Compliance: Navigating Complex Airspace
Modern UAS technology demands seamless integration into contested, urban, and international airspace. This involves:
• Airspace Management: Aligning operations with international standards such as ICAO guidelines and NATO protocols ensures interoperability with allied forces and manned systems.
• Data Protection: Advanced drones rely on high-resolution sensors and AI for analysis. This raises concerns about data sovereignty, especially when third-party software or hardware is involved. Contracts must safeguard sensitive military data to prevent exploitation.
________________________________________
2. Agile Procurement: Avoiding the Trap of Outdated Systems
The Defence Secretary’s comments highlight the inefficiencies of long, rigid procurement processes that often lock the MOD into outdated technologies. From a legal perspective, embracing agile procurement could address this issue:
• Flexible Contracts: Including provisions for mid-term upgrades ensures that UAS technology can evolve alongside emerging threats.
• Modular Design: Contracts should require systems to support modular enhancements, reducing the risk of obsolescence.
• Innovative Financing: Leasing agreements or performance-based logistics contracts can lower initial costs while ensuring rapid scalability.
However, these models come with legal complexities. For example, leasing agreements must clearly define ownership of intellectual property (IP) and establish mechanisms to avoid vendor lock-in.
________________________________________
3. Resilience to Legal Challenges in Conflict Zones
Resilience is not just about withstanding extreme weather or jamming—it is also about surviving scrutiny under international humanitarian law (IHL). Modern drones must be:
• Legally Compliant: Operational transparency is essential to demonstrate adherence to the principles of distinction and proportionality under IHL.
• Accountable: Enhanced sensors not only improve battlefield performance but also create an audit trail for decision-making, reducing the risk of legal disputes or allegations of unlawful actions.
________________________________________
4. Liability and Risk Management
Deploying smaller, more agile drones introduces new liability challenges. For example:
• Urban Operations: If a drone causes collateral damage during a mission, who bears responsibility—the MOD, the contractor, or the manufacturer?
• Coalition Forces: Legal frameworks must address accountability in joint operations with allied forces, where differing legal standards may apply.
These questions demand robust legal agreements and clear operational protocols to mitigate risk.
________________________________________
The Path Forward: Legal Resilience as a Core Requirement

For the UK to maintain a competitive edge in defence, its drone fleets must not only excel operationally but also withstand the scrutiny of legal and regulatory frameworks. A modern fleet must be:
1. Interoperable – Capable of integrating seamlessly with allied systems while adhering to international airspace laws.
2. Modular – Designed for upgrades to counter evolving threats and meet new legal standards.
3. Transparent – Equipped with sensors that provide clear evidence for operational decisions, enhancing accountability.
4. Compliant – Procured under contracts that mitigate risks of misuse, proliferation, or IP disputes.
________________________________________
Conclusion: Future-Proofing the UK’s Drone Strategy

John Healey’s emphasis on resilience offers an opportunity for the UK to rethink its approach to defence procurement. By embracing agile contracting, robust regulatory frameworks, and a forward-looking legal strategy, the UK can build a drone fleet that is not just operationally superior but also legally and ethically unassailable.
A truly modern military drone capability is one that is as resilient in the courtroom as it is in the field. The future of defence lies in aligning cutting-edge technology with agile, transparent, and robust legal strategies.

The report focuses on current regulations, primarily under the Civil Aviation Act 1982 and the Air Navigation Order 2016, as amended in 2018 (Order 2019 No.261).

It is now for most, common knowledge that Flight Restriction Zones (FRZ) exist around airports and is now 5Km, increased from 1Km.  It was a concern for Air Traffic Control operators that by increasing the disctance it would capture more drone pilots flying their drones and calling the ATC asking for permission to fly, thereby increasing the workload of those ATC operators. It is clear that there is an inconsistent approach by ATC’s in how they deal with drone operators and some taking an inordinate amount of time to approve such a request.  Some ATC’s are levying charges for permission!

The report refers to forthcoming regulation and names the Drones Bill, which passage on to the statute books has been halted due to Brexit and a General Election. However, there will be new legislation that was mentioned in the recent Queen’s Speech, namely the Air Traffic Management and Unmanned Aircraft Bill.  The new bill does include to an extent what the original drones bill was going to include:

1. Drone registration;
2. Remote pilot competency;
3. Personal details of drone operators.

The consensus around registration is that law abiding professional drone operators will at some poiint engage in registration, however those wishing to act illegally shall not, a point which was acknowledged by the CAA. The report recommends that those operators that avoid registration should be subject to a sliding scale of penalties for failure to register, starting with a warning, and culminating in a fine and a prison sentence.  You have been warned!
