Unlocking BVLOS: The Future Of Drone Operations In The UK

The drone industry is buzzing with the potential of Beyond Visual Line of Sight (BVLOS) operations. Imagine drones delivering packages across the UK, inspecting critical infrastructure with unparalleled efficiency, or providing emergency response in remote locations. This future is closer than you think, but as Gary Gutts, Future Flight Challenge Director, highlighted in his keynote at DroneX London, “achieving scalable, commercial success will be a team sport.”

So, what exactly will it take to make this leap to widespread BVLOS commercialisation in the UK? Let’s break down the key takeaways from Gary Gutts’ presentation, along with some additional insights.

Understanding BVLOS: A New Era of Drone Flight in the UK

Before we delve into the complexities of BVLOS commercialisation, let’s first clarify what exactly BVLOS entails and how it contrasts with current drone operations in the UK.

Currently, most drone flights in the UK are restricted to Visual Line of Sight (VLOS) operations. This means the drone pilot must maintain a direct visual connection with the drone throughout the flight. This limitation naturally restricts the operational range of drones and the types of applications they can be used for.

BVLOS, on the other hand, allows drones to fly beyond the visual range of the pilot, opening up a whole new realm of possibilities. Imagine drones autonomously navigating complex environments, delivering goods over long distances, or inspecting infrastructure in remote or hazardous locations – all without the need for a pilot to maintain visual contact.

Key Differences between VLOS and BVLOS:

• Operational Range: VLOS is limited to the pilot’s visual range, typically a few kilometres. BVLOS allows for much greater distances, potentially hundreds of kilometres.
• Applications: VLOS is suitable for tasks like aerial photography, videography, and inspections within a limited area. BVLOS enables more complex operations, such as long-range deliveries, infrastructure inspections over large areas, and search and rescue missions.
• Technology: VLOS relies primarily on the pilot’s visual perception and basic drone technology. BVLOS requires advanced technologies like autonomous navigation systems, reliable communication links, and sophisticated sense-and-avoid capabilities.
• Regulation: VLOS operations are generally subject to less stringent regulations. BVLOS flights require more complex approvals and safety protocols due to the increased risks associated with operating beyond the pilot’s visual range.

The Transition to BVLOS: A Gradual Process in the UK

The shift from VLOS to BVLOS represents a significant leap in drone technology and its potential applications. While the transition is underway, it’s important to acknowledge that it will be a gradual process, requiring careful planning, technological advancements, and robust regulatory frameworks to ensure safety and public acceptance.

The Road to Routine BVLOS in the UK: A Phased Approach

The journey towards routine BVLOS operations in the UK is being approached strategically, with a phased framework to ensure safety and manage the integration of drones into the airspace effectively. Here’s a glimpse into the key phases:

Phase 1: Early BVLOS Operations (Current)

This phase focuses on enabling BVLOS flights for specific use cases and in controlled environments. We’re seeing this with trials and projects involving:

• Beyond Visual Line of Sight trials: Companies like Amazon and Wing (US trials) are conducting trials for drone delivery services in restricted areas.
• Emergency services: Police and fire departments are utilising BVLOS drones for search and rescue operations and situational awareness in emergencies.
• Infrastructure inspections: Energy companies and infrastructure providers are using BVLOS drones to inspect power lines, pipelines, and other assets in remote locations.

Phase 2: Expanding Operational Scope

This phase involves expanding the scope of BVLOS operations to include more complex scenarios and broader applications. This will require:

• Enhanced safety regulations: Developing robust regulations and standards for BVLOS operations to ensure public safety and manage risks.
• Technological advancements: Improving drone technology, such as detect-and-avoid systems, communication networks, and autonomous navigation capabilities.
• Airspace integration: Integrating drones into the existing airspace safely and efficiently, working alongside traditional aircraft. Initiatives like Project Lifeline are exploring these integrations.

Phase 3: Towards Routine BVLOS (2027 and beyond)

This phase aims to establish routine BVLOS operations across various industries and integrate drones seamlessly into the national airspace. This will involve:

• Standardised procedures: Developing standardised procedures for BVLOS operations, including flight planning, risk assessment, and communication protocols.
• Public acceptance: Building public trust and acceptance of BVLOS drone operations through education and engagement.
• Scalability: Enabling the scalability of BVLOS operations to meet the growing demand for drone services across different sectors. The UK Civil Aviation Authority (CAA) is playing a crucial role in driving this roadmap, working closely with industry stakeholders and international partners to develop the necessary regulations and infrastructure for safe and efficient BVLOS operations.

The Two Pillars of BVLOS Commercialisation in the UK

Gary Gutts identified two crucial pillars that need to be addressed for BVLOS to truly take off in the UK:

Technical Challenges:

• Airspace Solutions: We need robust air traffic management systems that can safely integrate drones into existing airspace, alongside traditional aircraft. This includes developing technologies for detect and avoid (DAA) capabilities, real-time tracking, and communication systems.
• Infrastructure: Ground-based infrastructure, such as communication networks and charging stations, will be essential for supporting long-range BVLOS flights.
• System Reliability: BVLOS operations demand exceptionally high levels of system reliability to ensure safety and prevent accidents. This includes redundant systems, fail-safe mechanisms, and rigorous testing protocols.
• Aircraft Capability: Drones need to be capable of flying long distances, carrying payloads, and operating in various weather conditions. This requires advancements in battery technology, flight controllers, and sensor systems.
• Regulation: Clear and comprehensive regulations are crucial for governing BVLOS operations, addressing safety concerns, and enabling innovation. This includes licensing requirements, operational limitations, and airspace authorisation processes.

Socio-Commercial Challenges:

• Customer Demand: Building a strong market for BVLOS services is essential for commercial viability. This requires demonstrating the value proposition of drones in various industries and addressing any concerns about safety or privacy.
• Viable Economics: BVLOS operations need to be cost-effective to compete with traditional methods. This involves optimising operational efficiency, reducing maintenance costs, and maximising the utilisation of drone fleets.
• Social Licence: Public acceptance of BVLOS operations is crucial for widespread adoption. This requires addressing concerns about noise, privacy, and safety, and engaging with communities to build trust.
• Adaptability: The drone industry is rapidly evolving, and businesses need to be adaptable to keep pace with new technologies and regulations. This includes investing in research and development, embracing innovation, and staying informed about industry trends.
• People and Capital: A skilled workforce and sufficient investment are crucial for the growth of the BVLOS sector. This includes training drone pilots, developing software, and attracting funding for research and development. The Future Flight Challenge, a UK government initiative, is playing a key role in fostering this collaboration. By funding research and development projects, the program is accelerating the development of BVLOS technologies and supporting the creation of innovative solutions.

The Future of BVLOS in the UK: A Collaborative Effort

Gary Gutts emphasised the importance of collaboration in achieving BVLOS commercialisation. “Cross-industry, government, and regulator partnership are essential,” he stated. This means bringing together drone manufacturers, software developers, airspace management providers, regulators, and end-users to create a thriving ecosystem.
