CAA authorises trial of a concept for routine BVLOS operations

In a significant step forward for the drone industry, beyond visual line of sight (BVLOS) command & control solution developer has become the first company in the UK to secure authorisation from the UK Civil Aviation Authority (CAA) to trial a concept for routine Beyond Visual Line of Sight (BVLOS) operations. The permissions come as part of a test project to prove the concept ahead of potentially opening it up to the wider market.

The authorisation enables to fly BVLOS at three nominated sites without needing to pre-authorise each flight. By removing this limitation, this permission fires the starting gun for the next phase of growth of the drone industry, during which the potential of BVLOS to significantly increase operational effectiveness and efficiency will be considered.

The authorisation allows BVLOS flights to occur under 150ft and initially requires an observer to remain in visual line of sight with the aircraft and able to communicate with the remote pilot if necessary. By testing the concept in industrial environments for inspection, monitoring and maintenance purposes, aims to prove the safety of its system within this context initially, before extending it to address increasingly challenging missions over time.

Innovators and the CAA continue to work on solutions to further the safety of future missions through new technologies such as automatic detect and avoid systems. Data gathered from these test flights will be used to consider the success of the operations and whether the risk and hazard assessments can be used to cover generic risks beyond the three trial sites.

This significant step forward was delivered under guidance from the UK CAA Innovation Sandbox. The Sandbox was set up in May 2019 to create an environment where innovation in aviation can be explored in line with CAA core principles of safety, security and consumer protection., whose senior team includes ex Arup, Apple, CERN, McLaren and hedge fund employees was one of the first entities selected into the Sandbox in September 2019.

The authorisation is also an early win for UK Research & Innovation’s recent aviation & aerospace initiative, the Future Flight Challenge. Within the current ‘Phase 2’ of this Challenge, is leading a project to enable commercial BVLOS drone services at scale alongside manned aviation. Backed by government grant funding and supported by technical partners including NATS, BAE Systems, Vodafone, Met Office, Flock and the University of Bristol’s Smart Internet Lab, this project will put’s BVLOS solution in the hands of two of the world’s leading drone service providers, TerraDrone and SkyFutures, to address ten increasingly challenging trials with end-clients including Skanska, Skanska Costain STRABAG working in partnership with HS2, Sellafield, Vodafone, Lancashire Fire and Rescue Service, Network Rail and Atkins.

John McKenna, CEO at said:

“We are accelerating towards a future where drones fly autonomously at scale – high up alongside manned aviation and low down inside our industrial sites, suburbs and cities. Securing this UK-first permission is a major step on this journey which will deliver big benefits to society across public health & safety, efficiency and environmental impact. We are hugely grateful to the CAA’s innovation & regulatory teams for their support and guidance in helping us reach this significant milestone and we look forward to working with them as we continue to advance what’s safe and possible.”

David Tait, Head of Innovation at the UK Civil Aviation Authority, said:

“Our innovation team was set up to meet the rapid pace of technological advances in the UK, so to see businesses like thriving and creating world-leading solutions that will benefit infrastructure and markets is really exciting.

“We are proud to have played our part in sustaining the UK’s position as one of the greatest locations in the world for innovative companies.”

Unless they have specific permissions, all other drone operators must keep their aircraft within line of sight and follow the drone code.

ABOUT SEES.AI’s technical approach mirrors that of autonomous car developers i.e. putting highly automated machines to work at scale under remote human supervision, gathering data and learnings as they fly, and using this information and their track-record, to safely iterate towards full autonomy.

From a start point in industrial environments, the team aims to extend hand-in-hand with the regulator to address increasingly challenging use-cases, ranging from infrastructure inspection in the public domain (electricity networks, rail, road etc) to emergency service use-cases in temporarily controlled environments (fire & police) and potentially even to logistics and mobility in time.

The solution has been designed from the ground up to safely handle challenges such as: ensuring precise and reliable navigation in unknown, unstructured and evolving environments; and mitigating against GPS-denial, intermittent comms and magnetic interference. By addressing these challenges up-front, believes it is developing a solution that, ultimately, has far greater potential to scale. is the only entity selected into both the CAA Innovation Sandbox and the UK Government Drone Pathfinder – the latter backed by the Department for Transport, the Department for Business Energy & Industrial Strategy and the CAA.


Making the flying of unmanned aircraft beyond the visual line of sight of the operator a safe everyday occurrence is one of the top asks of innovators around the world. The CAA has published a roadmap of how the sector can get to routine BVLOS flying on its website:


The UK Civil Aviation Authority (CAA) is the UK’s aviation safety and consumer rights regulator. The organisation was created by Parliament in 1979 as an independent regulator. In 2019, the CAA set up a new innovation team and our Innovation Sandbox to help tech innovators working on new aviation concepts to take their ideas to market in a safe, secure and sustainable way.


The CAA’s Innovation Sandbox, initially funded by a grant from the Department for Business, Energy and Industrial Strategy (BEIS), is a safe and collaborative environment within which innovators can develop and test new aviation solutions. Companies within the sandbox work alongside the Civil Aviation Authority’s innovation team to understand how their innovative solutions can address the risks and unknows in terms of safety, security and consumer protection. Bridging the gap between regulator and innovator is a radical shift from the traditional approach to regulation. was the seventh entity selected into the Sandbox in September 2019. The Sandbox is now working with 12 entities including, Amazon, Boeing, NATS and Volocopter.
