A £300m government initiative promised a new era of drones and flying taxis. But an official evaluation reveals an industry plagued by regulatory delays, a lack of commercial focus and an infrastructure gap that threatens to leave the UK lagging behind international rivals.
When the government launched the Future Flight Challenge in 2019, it promised to position Britain at the vanguard of the third aviation revolution. The £300m initiative – combining £125m in public funds with a minimum of £175m from industry – was designed to propel unmanned aerial systems, advanced air mobility and regional electric aircraft from the drawing board into the skies.
Yet a newly published final evaluation of the programme paints a sobering picture of a sector struggling to translate research and development into viable commercial services. Hamstrung by regulatory bottlenecks, a precarious funding landscape and profound infrastructure deficits, the industry’s ambitions are at risk of remaining permanently grounded.
The comprehensive evaluation, conducted by Frontier Economics, Frazer-Nash Consultancy and BMG Research, confirms that while the initiative successfully fostered collaboration and leveraged an impressive £217m in industry co-investment, the transition to in-service operations has severely stalled. For the small and medium-sized enterprises at the heart of this innovation, the failure to clear these hurdles presents an existential threat.
The regulatory bottleneck
The most persistent grievance among industry pioneers is the sluggish pace of regulatory approval. The Civil Aviation Authority, the UK’s aviation regulator, is widely perceived by the industry as a severe bottleneck. According to the evaluation survey, 51% of respondents now view regulation as a barrier to technological progress, while the proportion rating the regulator’s demonstration approval process as ‘extremely inefficient’ has surged from 9% at the interim evaluation to 23%.
Industry insiders suggest that post-Brexit resource constraints have severely hindered the regulator’s capacity to keep pace with rapid technological advancements. ‘In the past few years, we have dealt with the consequences of Brexit, which significantly hindered CAA’s capacity to develop regulation as quickly as other countries,’ noted one regulatory stakeholder.
The consequences of these delays are stark. A staggering 41% of respondents believe the UK now lags behind most countries in regulatory innovation, a sharp increase from just 17% when the programme began. Competitors in the US are benefiting from larger funding pools and flexible waiver approaches for commercial drone operations, while European Union countries enjoy a greater uptake of electronic conspicuity devices among traditional aircraft. Meanwhile, nations such as Canada and Australia capitalise on vast unoccupied spaces for testing, and China has aggressively designated airspace below 500ft exclusively for drones.
In Britain, testing has often been confined to isolated temporary danger areas, which fail to replicate the complex, integrated airspace required for business-as-usual operations. While the recent introduction of the UK Specific Operations Risk Assessment – developed in collaboration with the British Standards Institution – provides a glimmer of hope for a more flexible framework, stakeholders warn that the regulatory timeline remains wildly out of sync with commercial realities.
‘The UK has traditionally been seen as a gold standard regulator, it is very well respected in terms of BVLOS [beyond visual line of sight] policies, but it is definitely not top of the world because it is harder in the UK than in other countries,’ admitted a regulator interviewed for the evaluation.
The ‘valley of death’ for small businesses
The financial realities facing future flight enterprises are equally daunting. While the Future Flight Challenge successfully seeded the market and supported groundbreaking projects, the industry is now confronting a perilous ‘valley of death’ between prototyping and commercialisation.
SMEs, which comprise the bulk of the sector’s innovators, warn that current funding levels are barely sufficient to keep the lights on. Many fear that once the programme concludes in 2025, they will not survive more than 12 months without sustained, long-term investment. The proportion of survey respondents viewing private sector investment as a barrier has more than doubled, rising from 15% at baseline to 32% in the final evaluation.
Economic uncertainty, inflation and post-Brexit complications have cooled investor appetite, leaving UK firms at a distinct disadvantage compared with their US and EU counterparts. As one industry figure put it, there is a risk that the UK will endure a ‘lost decade’ of innovation if government support dries up and domestic start-ups are either forced into administration or bought out by foreign competitors.
‘The UK is known for promoting innovation but struggles historically to commercialise,’ observed one industry stakeholder.
Commercialisation spread too thinly
A recurring criticism in the evaluation is that the programme spread its funding too thinly across a myriad of futuristic use cases, rather than concentrating resources on bringing a select few to commercial maturity.
‘If you try to do too much, then you end up not getting any of those to market and we don’t go anywhere,’ lamented one large organisation representative. Instead of demonstrating an end-to-end commercial service – which would validate business models, supply chains and regulatory pathways – projects often remained stuck in the prototyping phase.
Despite these missteps, some projects have successfully showcased the potential of future flight technologies. Project CAELUS has trialled the distribution of medical products and medicines across Scotland using a network of electric drones, while Open Skies Cornwall is establishing ‘sky highways’ to connect the NHS, Royal Mail and local authority assets. Similarly, Project Lifeline has demonstrated how drones can deliver critical medical equipment such as defibrillators and anti-bleeding kits directly to emergency scenes.
However, these successes represent a fraction of the sector’s broader potential. The evaluation notes that a robust future flight supply chain is virtually non-existent, leaving manufacturers without the raw materials, energy and transportation networks required to scale up operations.
The infrastructure and skills deficit
This lack of commercial readiness is further complicated by the UK’s crowded and complex airspace. The slow uptake of electronic conspicuity devices among traditional general aviation users makes integrating drones and air taxis an incredibly thorny issue. Furthermore, the physical infrastructure required to support these new vehicles – such as vertiports, charging stations and robust electricity networks – is severely underdeveloped.
The sector is also grappling with a growing skills deficit. As projects advance towards higher technology readiness levels, the demand for specialised expertise in digital technologies, systems engineering, autonomous systems oversight and uncrewed traffic management has skyrocketed. Correspondingly, 38% of survey respondents now view workforce skills as a barrier, up from just 18% when the programme launched.
While the challenge allocated £500,000 towards upskilling programmes and educational outreach, including partnerships with the Institute of Engineering Technology, industry leaders warn that bridging this gap will require a far more comprehensive national strategy.
Net zero illusions and public scepticism
The promise of zero-emission flight has been a central pillar of the initiative, aligning with the government’s ambitious net zero targets. Electric and hydrogen-powered air vehicles produce no operational carbon emissions, offering a tantalising alternative to diesel-powered freight and passenger transport. A report published by PwC estimated that future flight technologies could reduce carbon emissions in the UK by 222 million tonnes of CO2e per year by 2040, providing an equivalent of over £24bn in monetary value to society.
Yet, the evaluation reveals that the industry has done little to quantify the full lifecycle environmental impact of these technologies. The carbon footprint of battery manufacturing, electricity grid emissions and end-of-life disposal threatens to offset operational savings. Without rigorous, scaled-up environmental modelling, the net zero benefits of future flight remain largely theoretical.
Public perception is similarly precarious. Research conducted alongside the programme found that while 95% of the UK public are familiar with drones, a mere 28% have heard of electric vertical take-off and landing vehicles. Although there is broad support for operations that serve the public good – such as emergency medical deliveries or rural connectivity – significant anxieties persist regarding privacy, noise, safety and visual pollution.
Qualitative research from a deliberative public dialogue revealed that citizens expect these technologies to align with public good principles, including affordability, inclusivity and environmental sustainability. Industry veterans caution against the marketing hype surrounding flying taxis. Overpromising futuristic passenger services without first demonstrating safe, routine operations risks alienating a sceptical public.
‘By attempting to achieve something great and not quite getting there, we might have ended up doing something damaging,’ warned one SME leader.
The wider economic footprint
Despite the profound challenges, the potential prize for the UK economy is vast. Companies operating in sectors similar to Future Flight Challenge applicants generated £302bn in turnover in 2023, contributing approximately 4.8% of the UK’s total private sector turnover. This share is comparable to established industries such as construction and information technology, drastically dwarfing the traditional aviation sector, which accounts for less than 1% of the UK’s total turnover.
Gross value added for these wider industries grew by 6% between 2019 and 2022 to reach £288bn, driven largely by non-aviation activities such as business support, consultancy and computer programming, which collectively underpin the future flight ecosystem. If the UK can overcome its regulatory and infrastructure hurdles, the integration of these high-tech services could fundamentally reshape the domestic economy.
A crossroads for UK aviation
The Future Flight Challenge has undoubtedly catalysed a nascent industry, forging unprecedented collaborations and driving critical technological advancements. It has provided a vital platform for British businesses to showcase their innovations on the global stage at events like Farnborough International Airshow. However, the transition from successful test flights in segregated airspace to a thriving, economically viable sector requires a fundamental shift in strategy.
The evaluation underscores an urgent need for a cross-departmental government vision that extends beyond short-term research grants. Regulators must be properly resourced to create flexible, innovation-friendly frameworks, while the industry itself must focus relentlessly on commercialising practical, low-risk use cases rather than chasing disparate technological dreams.
Without a coordinated national effort to build the necessary physical and digital infrastructure, secure long-term private investment and bring a sceptical public on board, Britain’s ambition to lead the third aviation revolution may well remain permanently grounded.

On 20 May 2026, the Law Commission published its final report on aviation autonomy. Commissioned by the Department for Transport and the Civil Aviation Authority, the review addresses the legal barriers to safely deploying highly automated and autonomous systems in aviation. It focuses on three main use cases: drones, advanced air mobility such as vertical take-off and landing aircraft (VTOLs), and air traffic management. The overarching aim is to ensure that uncrewed aircraft systems (UAS) can operate with safety levels equivalent to crewed flights.
A central element of the report is drawing a clear line between remotely piloted and autonomous operations. To ensure legal certainty regarding who is responsible for aviation safety, the commission recommends that any flight where a human pilot can intervene should be classed as remotely piloted, while any flight without this possibility is autonomous. It advises retaining the current legal definition of a remote pilot and aligning their responsibilities with those of a commander in commercial air transport operations.
For passenger-carrying remotely piloted operations, ensuring equivalent safety with crewed aircraft is paramount. The remote pilot will hold ultimate legal responsibility for flight preparation checks, such as ensuring the aircraft is airworthy and that cargo is secured. Furthermore, the remote pilot will have the responsibility to refuse transport to individuals under the influence of drink or drugs. They will also be granted the power to take reasonable measures, including authorising passenger restraint under the Civil Aviation Act 1982, to protect the aircraft and its occupants in emergency situations. Operators will be required to ensure that passengers can contact a crew member at all times.
When operations become fully autonomous, the responsibilities of the pilot will shift significantly to the UAS operator. The operator will be required to use an aircraft designed to comply with operational limitations and avoid the risk of collision. Mandatory flight data recorders are also recommended for autonomous drone and VTOL operations to facilitate accident investigations and improve long-term safety.
The report also examines civil and criminal liability when accidents happen. It states that the current strict liability system will continue to function effectively for air carriers, although product liability relating to artificial intelligence requires a broader review. In terms of criminal law, the commission recommends updating the offence of hijacking under the Aviation Security Act 1982. Recognising that uncrewed aircraft could be seized by technological means or hacking without a hijacker being present on board, the report urges the UK to implement the Beijing Protocol to expand the legal definition of hijacking.
Finally, to safely integrate uncrewed flights beyond the visual line of sight, the report calls for legislative change to accommodate the certification of uncrewed aircraft systems traffic management (UTM) providers. These services will supply vital digital information about potential hazards and weather to uncrewed aircraft, ensuring they can share the airspace safely with crewed flights.

The Civil Aviation Authority (CAA) published a consultation document, CAP3240, to establish a regulatory policy framework for new types of vertical take-off and landing aircraft. The UK government has stated an objective to see piloted electric vertical take-off and landing operations in the UK from 2028. To meet this goal, the CAA aims to implement a clear regulatory framework that permits initial commercial passenger flights. The consultation received 28 responses, with 85% expressing positive views on the proposals. The approach seeks to use existing aviation regulatory frameworks where possible, only introducing bespoke requirements when technological or operational characteristics render existing rules unsuitable.
Definitions and Classifications A core component of the framework involves defining these new vehicles. The CAA proposes updating the existing UK definition of a powered-lift aircraft to capture most new vertical take-off and landing aircraft, aligning with International Civil Aviation Organisation standards. However, some new aircraft operate similarly to helicopters but lack the capability to perform an autorotation (or an equivalent safe forced landing alternative) in the event of power failure or energy depletion. The CAA will classify these as non-conventional helicopters. By treating them as a subcategory of helicopters, regulators can apply targeted requirements to mitigate specific safety risks without burdening conventional helicopter operations. The propulsion architecture itself—whether using vectored thrust or independent lift and cruise motors—will not affect the classification, as the rules are intended to be technologically agnostic. Where an aircraft does not neatly fit into existing statutory definitions, the CAA will retain the discretion to determine the most appropriate classification.
Complex Motor-Powered Aircraft Under the framework, powered-lift aircraft and non-conventional helicopters will be treated as complex motor-powered aircraft by default. Respondents broadly agreed that the novelty, complexity and safety-critical nature of these vehicles—such as their highly integrated systems and distributed propulsion architectures—justify this stringent classification. This classification ensures that operational risk remains equivalent to legacy commercial aviation. Nevertheless, the CAA proposes a discretionary power to exempt certain aircraft from this category, provided there is a clear and transparent decision-making framework, which will be the subject of further consultation.
Airworthiness Standards The framework establishes robust standards for both initial and continuing airworthiness. For initial airworthiness, the CAA will use the existing framework set out in Part 21 of UK Regulation (EU) No. 748/2012. Respondents strongly supported this, noting that the current system is familiar, internationally consistent and highly capable of integrating novel technologies while maintaining public confidence. No respondents completely disagreed with this approach, although some cautioned against over-regulating smaller aircraft under 600kg, which might possess different risk profiles.
Similarly, continuing airworthiness will fall under the established requirements of UK Regulation (EU) 1321/2014. This approach ensures that new vertical take-off and landing aircraft meet the same rigorous maintenance and safety standards as the wider aviation industry. The CAA will explore allowing pilot-owner maintenance for normal tasks, while restricting pilot maintenance on complex systems such as flight controls.
Pilot Licensing Developing a competent workforce is essential for the future of flight. The framework outlines a personnel licensing pathway that allows existing commercial pilot licence and airline transport pilot licence holders to secure a type rating for new vertical take-off and landing aircraft. The CAA will also create a pathway for private pilot licence holders to fly these aircraft non-commercially. At this stage, the CAA is not proposing an ab-initio training route for novice pilots. Instead, training will rely on operational suitability data established by manufacturers, offering a standardised, data-driven process for type ratings. Several consultation respondents suggested that competency-based training might be more effective than traditional flight-hour metrics given the advanced automation of these aircraft, and the CAA has committed to exploring these alternatives.
Flight Operations and Aerodromes For flight operations, the CAA intends to apply existing aeroplane and helicopter requirements equitably. However, bespoke updates are necessary for flight time limitations and energy management policies. Because vertical take-off and landing aircraft rely heavily on automated systems, the CAA acknowledges that pilot workload may differ from conventional flying, necessitating a review of single-pilot fatigue regulations. Furthermore, energy reserve requirements will be dictated by the specific landing mode used by the aircraft.
Finally, aerodrome regulations will align with the forthcoming heliport certification and safety management systems framework. The CAA plans to modernise the guidance to reflect the physical characteristics of powered-lift aircraft, such as downwash and outwash. The framework will also support the shared use of aerodromes and vertiports to reduce infrastructure costs and foster commercial viability, while maintaining pathways for commercial operations at unlicensed operating sites.
Further consultations will be conducted to refine the specific legislative text and detail, ensuring continuous alignment with international colleagues and mitigating the risk of market fragmentation. Once concluded, the CAA will deliver its final instructions to the Department for Transport to consider progressing these proposals into statutory instruments.
