YARI V6X is an enterprise-grade FMUv6X modular flight controller and autopilot platform for demanding small unmanned vehicle missions. It is designed and built in India for teams developing copters, planes, VTOLs, rovers, boats, underwater ROVs, and other robotics platforms.
V6X is built for developers, system integrators, manufacturers, research teams, defense teams, commercial operators, and builders who need reliable onboard flight-control hardware without leaving the PX4 and ArduPilot ecosystems.
Why We Built V6X
Small unmanned vehicle teams often work at the boundary between open-source autopilot software, custom payloads, companion computers, sensors, radios, power systems, and field conditions that are rarely gentle.
The flight controller sits at the center of that system. It has to handle vehicle state estimation, sensor timing, vibration, logging, power transitions, firmware updates, and integration with the rest of the autonomy stack.
YARI V6X was built to give teams a modern, serviceable, Pixhawk-compatible platform for that work. It follows the FMUv6X and Pixhawk Autopilot Bus open standards, while adding YARI’s own focus on sensor isolation, vibration performance, active IMU thermal stabilization, rugged packaging, documentation, and field validation.
Built On Open Autopilot Standards
V6X is based on the FMUv6X and Pixhawk Autopilot Bus standards. The standard set includes the YARI V6X Flight Controller Module and the YARI Pixhawk Autopilot Bus Carrier, giving teams a modular autopilot platform that can fit into Pixhawk-compatible workflows.
The product ships with ArduPilot support and can be flashed with PX4. YARI V6X board support is already merged into ArduPilot master, and supported firmware downloads are available from the YARI documentation site while official release and ground-station packaging catches up.
That matters because teams do not need to choose between a modern hardware platform and familiar autopilot workflows. V6X is designed to work with the tools, firmware projects, and integration patterns that unmanned vehicle teams already use.
Hardware Designed For Demanding Missions
YARI V6X combines redundant sensing, thermal control, vibration isolation, and high-performance flight computation in a compact autopilot platform.
Key hardware highlights include:
- STM32H743 MCU running up to 480 MHz.
- Modular FMU, IMU, and PAB carrier architecture.
- 3x IIM-42653 SmartIndustrial IMU array with extended temperature support.
- Redundant isolated sensor domains with dedicated communication buses and independent power control.
- Active IMU heating for consistent sensor performance across changing environmental conditions.
- Custom vibration-isolation material for high-vibration airframes.
- CNC-machined aluminum flight-controller enclosure.
- Ethernet, additional telemetry, debug, and integration interfaces on the YARI carrier board.
Tested In The Field And In The Lab
YARI V6X has been validated through field flight testing and NABL-accredited lab testing. The product has cleared environmental and EMC testing in NABL-accredited labs, with tests performed in operational condition with continuous data logging where applicable.
EMC testing covered CISPR 32 conducted emissions, CISPR 32 radiated emissions, IEC 61000-4-2 ESD immunity, and IEC 61000-4-3 radiated immunity.
Environmental testing covered IEC 60068 low air pressure, cold, dry heat, temperature change, random vibration, shock, and damp heat cyclic methods.
Full test reports are available upon request for qualified customers, integrators, and enterprise evaluations.
Designed And Built In India
YARI V6X is designed and built in India. For V6X, that means significant manufacturing value add happens through our India-based network, including activities such as PCB fabrication, PCB assembly, final assembly, testing, packaging, and related manufacturing operations depending on the production stage and component availability.
Electronic components such as ICs, passives, and semiconductors may be sourced globally based on availability and technical requirements. But the product direction, integration, validation, and manufacturing value add are rooted in India.
That matters to us because small unmanned vehicle teams need dependable hardware, clear documentation, and an engineering team that understands the product beyond a reseller catalog.
Documentation, Firmware, And Integration Support
A flight controller is only useful when teams can actually integrate it, update it, debug it, and ship vehicles with it.
The YARI documentation site includes V6X overview, setup, downloads, FAQ, pinout, troubleshooting, compliance and testing summaries, firmware downloads, CAD files, and datasheet links. Supported downloads include ArduPilot firmware for Copter, Plane, Rover, and Sub, PX4 firmware variants, bootloaders, CAD models, and the V6X datasheet.
V6X also supports Ethernet workflows for MAVLink connectivity with direct PC, companion-computer, and ground-station setups. That gives teams another practical path for integration, especially when vehicles use companion computers or more demanding payload and data workflows.
Built Through Field Testing, Automation, And Iteration
Before launch, YARI V6X went through repeated field flights, thermal checks, vibration-focused testing, automated hardware validation, and endurance runs. That work shaped the product and helped us validate the controller as a serious platform for demanding unmanned vehicle development.
The validation work included stable hover flights, high-vibration stress testing, mission-style flight reviews, onboard IMU-heater checks, ArduPilot hardware report reviews, and full-system flights with YARI V6X, YARI GNSS, YARI Power Module, and AM32 ESC hardware working together.
We also built internal hardware test automation around V6X. That included automated serial-port validation, custom test jig development, custom test firmware, close to 100% hardware test coverage, and a week-long endurance run with continuous onboard SD-card logging.
Most field-flight validation so far has been on multicopter platforms. Our next focus is to keep expanding validation across more vehicle types, scale production, and streamline the processes around testing, assembly, documentation, and support.
V6X is the first product we are bringing to market, but it is not a one-off board. It is the onboard hardware foundation for the broader YARI product stack around small unmanned vehicles, autonomy development, and reliable field operations.
Built On Shared Foundations
YARI V6X stands on the shoulders of open-source autopilot projects and hardware standards including PX4, ArduPilot, and Pixhawk. We inherited good design concepts that already exist in the ecosystem instead of reinventing the wheel, and built on those foundations to create a reliable, documented, and indigenized flight-controller platform for YARI’s autonomy stack.
We are grateful to the open-source contributors and maintainers whose work made this possible, including the maintainers who reviewed and helped merge YARI V6X board support. For us, this foundation matters because dependable onboard hardware is one of the critical building blocks for small unmanned vehicles, autonomy development, and field operations.
Availability
YARI V6X pre-orders open on August 15, 2026, with worldwide shipping. Pre-order units are expected to ship in about 2 months.
Pre-orders help us get the first production cycle started. As we scale, the goal is to improve demand forecasting, lock in long-lead-time components earlier, manufacture larger batches, and keep YARI V6X inventory in stock more consistently.
Pre-order customers receive a 10% launch discount. B2C customers can place orders directly through the portal. For B2B or bulk orders, email [email protected].

MBF Group S.A., a company listed on the NewConnect market, is developing two complementary directions in the field of unmanned aerial systems. IRYDA+ X1 remains the platform currently being prepared for commercialisation and presentation to potential customers, while the formally launched IRYDA+ SPACE Z1 programme is intended to represent the next stage of development, based on space-enabled technologies, artificial intelligence, autonomy, satellite communications and advanced mission management.
The Company emphasises that SPACE Z1 is not intended to replace X1. The new programme is a natural consequence of the current platform reaching a stage at which commercial preparations can begin and the experience gained can be used as a foundation for the next generation of systems. MBF Group intends to follow a model in which a product that is ready today is commercialised while, in parallel, work begins on solutions that may respond to market and operational needs in the years ahead.
IRYDA+ X1 remains the most important practical element of the Company’s UAV programme at present. Work is underway to finalise technical documentation, available configurations, delivery terms, service arrangements and technical support, while one of the nearest objectives is to complete documentation required for further institutional procedures. The platform is also expected to be presented during MSPO 2026 in Kielce, and MBF Group is conducting discussions regarding potential commercial applications of X1 with entities from Poland and other European Union countries.
SPACE Z1 is intended to address a broader shift in the way modern unmanned systems are designed and assessed. Technological advantage increasingly depends not only on the performance of the aircraft itself, but also on its ability to communicate, obtain and process data, operate beyond direct line of sight and cooperate with other elements of the operational environment. For this reason, the scope being analysed for SPACE Z1 includes, among other areas, satellite and hybrid BLOS communications, encrypted telemetry, the use of satellite infrastructure and Earth observation data, EO/IR systems, edge computing, sensor fusion, AI-supported image analysis, Digital Twin technologies and resilient navigation.
MBF Group has already initiated discussions with selected Polish companies possessing competencies in space technologies, satellite communications, optics, imaging and data processing. At this stage, the names of the potential partners are not being disclosed due to the preliminary nature of the discussions, the absence of binding agreements and applicable confidentiality and compliance requirements. SPACE Z1 is intended to remain open to technology companies, universities, R&D centres and industrial partners from Poland and abroad.
An important part of the strategy is also the potential development of future production capabilities in Poland. Requirements currently being analysed for IRYDA+ X1 are expected to be expanded to include the future needs of SPACE Z1, including electronics, communications systems, optoelectronics, AI, software and research and testing infrastructure. MBF Group’s intention is, where technologically and economically justified, to locate as much production, integration and R&D competence as possible in Poland.
At the same time, the Company has announced the convening of an Extraordinary General Meeting for 14 September 2026. The agenda includes, among other matters, draft resolutions concerning an increase in share capital and the formal expansion of the Company’s business activities to include the design, production, sale, servicing, research and development of unmanned aerial vehicles and activities related to modern technologies.
One of the most notable elements of the proposed Series K share issue is the planned private offer to Radosław Majdan. According to the draft resolution, he would be offered 160,000 shares at an issue price of PLN 6.25 per share, for a total amount of exactly PLN 1,000,000. The draft also provides for a voluntary 12-month lock-up commitment, intended to underline the long-term nature of the planned investment.
Radosław Majdan had already declared his interest in a capital investment in MBF Group and the IRYDA+ X1 project. The current draft resolutions specify the proposed scale of this commitment at PLN 1 million and are intended to formalise its long-term character. From the Company’s perspective, this is an important signal that an investor known primarily from the worlds of sport and media has chosen to allocate part of his own capital to a Polish public company developing UAV, dual-use and next-generation technology projects.
The proposed share issue has not yet been completed and remains subject to the adoption of the relevant resolutions by the General Meeting and the completion of the subsequent legal and corporate procedures. The documentation prepared for the meeting indicates that proceeds from the Series K issue are intended to support the Company’s operating activities, technology and defence projects, working capital and the commercialisation costs of new ventures.
For MBF Group, these developments form part of one broader growth path: a functioning IRYDA+ X1 platform being prepared for commercial use, the launch of the next-generation SPACE Z1 programme, the search for technology partners and future production capacity in Poland, and the preparation of financing instruments for further growth. During MSPO 2026, the Company intends to present X1 as the result of work already completed, while SPACE Z1 is expected to be presented as the technological direction for the next stage. The objective is to commercialise what is ready today while simultaneously building the capabilities required for the technologies that may define the market of tomorrow.

Over the years, I’ve had the privilege of working with some exceptional operators, engineers, regulators and test teams. They all came from different organisations, had different experiences, and often approached problems in completely different ways. Yet, looking back, I’ve realised they all seemed to share one habit.
They asked better questions.
Not more questions. Better ones.
It wasn’t always obvious at the time, and I doubt many of them consciously followed the same process, but the pattern has become increasingly clear to me. The strongest operational decisions I’ve witnessed have almost always been preceded by four simple questions.
They’re not unique to aviation and they’re certainly not unique to UAS. In fact, I’d argue they apply to almost any complex activity where people, technology and uncertainty come together.
They’re also deceptively simple.
What do we believe?
How do we know?
What are we assuming?
What would change our mind?
On the surface, they sound almost too straightforward to be useful. In reality, I’ve found they expose weaknesses in an operation remarkably quickly.
The first question is usually the easiest.
What do we believe?
Every operation begins with beliefs. We believe the aircraft can achieve a particular endurance. We believe the command and control link is sufficiently robust. We believe the weather forecast is accurate enough to support the mission. We believe our procedures are appropriate, and we believe the people carrying them out understand them.
There’s nothing wrong with belief. In fact, planning would be impossible without it. The problem is that beliefs have a habit of becoming facts in our own minds long before they’ve earned that status.
That’s why the second question matters so much.
How do we know?
It’s surprising how often this question changes the conversation.
I’ve sat in meetings where everyone around the table was convinced a particular capability existed, only for somebody to ask how we actually knew. Suddenly the discussion changed from certainty to evidence. Instead of repeating assumptions, people began searching for demonstrations, test results, operational experience and observations that genuinely supported the claim.
Sometimes the evidence was there.
Sometimes it wasn’t.
And occasionally everyone realised they had simply inherited somebody else’s confidence.
That’s an uncomfortable moment, but it’s also an incredibly valuable one.
The third question is where things become even more interesting.
What are we assuming?
Every operation contains assumptions. They aren’t signs of poor planning; they’re an unavoidable consequence of working in uncertain environments. We assume radio performance will remain consistent. We assume GNSS coverage will be available. We assume operators will behave in predictable ways under pressure. We assume the environment won’t introduce something we’ve never encountered before.
The danger isn’t that assumptions exist.
The danger is that they slowly disappear into the background until nobody remembers they’re assumptions at all.
After enough successful flights, an assumption can quietly transform into “something we know”.
Except we don’t.
We simply haven’t challenged it recently.
I’ve come to think of assumptions as operational debt. Much like technical debt in engineering, they accumulate quietly while everything is working well. Most of the time they remain invisible, right up until the operation becomes more ambitious, more complex or moves into a new environment. Then suddenly that debt has to be repaid, often at exactly the moment you’d rather it didn’t.
The final question is probably my favourite because it says more about an organisation than almost anything else.
What would change our mind?
When I ask this during reviews or planning sessions, there’s often a pause.
Not because people don’t understand the question, but because they’ve never really considered it.
If our aircraft loses the command link under conditions we believed were well within its limits, would that change our understanding?
If a procedure that worked perfectly during rehearsals falls apart under operational pressure, would we rethink it?
If a regulator challenges an argument we’ve been confident about for months, are we prepared to revisit our thinking?
Or have we already decided we’re right?
To me, this is the point where testing and proving part company.
Testing accepts the possibility that our understanding is incomplete.
Proving begins with the assumption that we’ve already reached the answer.
One is driven by curiosity.
The other by confirmation.
The best operators I’ve worked alongside have always been willing to change their minds when the evidence demanded it. Not because they lacked confidence, but because they understood that confidence should follow evidence, not replace it.
Looking back over the articles I’ve written so far, I realise these four questions have been there all along.
The gap exists because belief and reality rarely align perfectly.
Evidence helps us understand what we actually know.
Assumptions explain why operations drift away from the plan.
Testing provides opportunities to change our minds before the real world does it for us.
Perhaps that’s why these four questions have become increasingly important to me. They aren’t really questions about aircraft or regulations.
They’re questions about thinking.
And if there’s one lesson the industry has taught me over the years, it’s that better operations rarely start with better answers.
They start with better questions.
—
The Four Questions
Before your next operation, test, design review or SORA, ask yourself:
- What do we believe?
- How do we know?
- What are we assuming?
- What would change our mind?
You might be surprised by the conversation that follows.

Sapient Perception is going stratospheric. The problem stays the same: small objects, large areas, in real time.
Detecting dark ships, monitoring the environment, protecting infrastructure across massive areas: all of it demands persistent coverage and high details at once.
We are joining NextGen Robotics III to solve exactly that, taking our perception stack to high-altitude platforms together with our partner Spaceline.
At that altitude, coverage comes easy and detail does not. That is the problem our stack solves: 10K sensors, mission-specific optics, and onboard edge processing through IGNITE:AI, working together to pick out small objects across wide areas and send intelligence down the data link instead of raw imagery. Paired with this stack, a stratospheric platform stops being a wide-area camera and becomes a real-time intelligence asset.
“At stratospheric altitudes, every pixel matters and every byte of bandwidth is precious. Sapient solves the fundamental challenge of high-altitude ISR, capturing enough detail across a massive area without overwhelming data links to the ground. That lets us turn persistent stratospheric surveillance into real-time actionable intelligence.” Simon Vilms Pedersen
The project is co-funded by the European Union through the European Regional Development Fund, under NextGen Robotics III with Erhvervshus Fyn.

Combining Rocket Lab’s launch, spacecraft manufacturing, and space systems expertise with Iridium’s global network and L-band spectrum will accelerate innovation, positioning the combined company to support the development and deployment of Iridium’s next-generation constellation. This includes direct-to-device (D2D/Iridium NTN DirectSM) services, which will grow into an important new capability for U.S. national security and emergency response, helping to ensure reliable, resilient communications when and where they are needed most, particularly where traditional networks are unavailable or compromised.
“This is a defining moment for the space industry and the start of a new era of strategic, accelerated growth for Rocket Lab and Iridium,” said Sir Peter Beck, founder and CEO of Rocket Lab. “Iridium has built the gold standard in secure, safety critical global satellite connectivity. It is relied upon by maritime fleets, the aviation industry, governments, and heavy industrial organizations who operate in the most remote off-the-grid locations. By marrying Iridium’s deep heritage, trusted infrastructure, and highly sought-after spectrum with Rocket Lab’s extensive and proven launch and manufacturing capabilities, we have the capability to unlock entirely new markets. We will go far beyond maintaining a legacy; we are going to build upon it to pioneer next-generation space applications and deliver sought-after capabilities to existing and new customers.”
“As the worlds of space and terrestrial communications continue to converge, more critical services will depend on space-based capabilities,” said Matt Desch, CEO, Iridium. “Success will come from those who can bring new innovations to space quickly and sustain them over time as efficiently as possible. We’re excited about being able to accelerate the next generation of IoT, aviation, maritime, PNT, and national security capabilities, and pursue new innovative applications as part of Rocket Lab – a fully integrated, end-to-end space company. That’s an incredible opportunity for our customers, partners, employees, and stockholders.”

ROLLA, Mo. — The Mars Rover Design Team at Missouri University of Science and Technology has won the University Rover Challenge for the second consecutive year, after competing against 35 teams from across the country and around the world.
“We didn’t go into it thinking we were world champions,” says Chase Stem, chief executive officer of the team and a 2026 graduate. “We’re a new team, a new group of students, a new leadership group, with a new rover.”
Held annually at the Mars Desert Research Station in Hanksville, Utah, the competition consists of science, delivery, equipment servicing and autonomous navigation missions, as well as a review of the rover’s design. The rover, designed and built by the students, was required to maneuver through soft sand and rocky terrain, around vertical drops and steep slopes, as well as navigate autonomously for certain parts of the challenge.
“One of our mottos is ‘we’re not people building a rover, we’re people building people,’” says Stem. “We really focus on the people that make the team. We were complimented by judges at every turn for our coordination and effectiveness at each task.”
The team scored 90.57/100 on the system acceptance review, based on a written report and a video detailing the capabilities of the rover. The video showcasing the rover, Athena, is available to view on Youtube.
Missouri S&T’s team shone in the equipment servicing mission and delivery missions, finishing both with a perfect score of 100. They finished in a five-way tie for first on the autonomous navigation mission, and in a tie for eighth on the science mission. The team’s final score was 469.57, over 50 points ahead of second place — and their own winning score from last year, 412.27.

There’s usually a moment in testing where things shift.
It’s not dramatic. Nothing fails. Nothing obvious goes wrong.
But you realise the plan you walked in with isn’t going to hold up.
It might be something small.
The environment behaves differently than expected.
The aircraft doesn’t respond quite how it did before.
The comms aren’t as clean as they looked on paper.
Or the sequence of events just doesn’t flow the way it was designed.
On paper, the test plan made sense.
Clear steps. Logical progression. Defined outcomes.
But reality isn’t linear.
It doesn’t care about sequencing or structure.
It exposes the assumptions built into the plan, usually earlier than expected.
This is the point where testing either becomes useful, or starts drifting.
The easy option is to force things back towards the plan.
Adjust slightly. Ignore the small gaps. Keep moving forward as if everything still aligns.
That’s where a lot of value is lost.
The better option is to recognise what’s actually happening and adapt to it.
Not by throwing the plan away, but by understanding what the plan didn’t account for.
That’s where the real learning sits.
Good testing isn’t about proving that the plan was correct.
It’s about exposing where it wasn’t.
And being able to adjust without losing control of the operation.
That moment is easy to miss if you’re only focused on getting through the test.
But once you start looking for it, it shows up in almost every operation.

The UK Civil Aviation Authority’s introduction of the Recognised Assessment Entity for Flightworthiness, or RAE(F), and the associated SAIL Marking system was presented as a way to support the rollout of UK SORA and help operators demonstrate that their unmanned aircraft systems are safe for more complex Specific Category operations.
In principle, few people in the drone industry would object to proportionate safety assurance. The problem is not the intent. The problem is the way the system risks becoming another costly layer of
assessment on top of standards, certificates, declarations and component-level compliance work that manufacturers have already completed.
The CAA says RAE(F)s are approved to assess whether the technical features of a UAS meet UK SORA requirements, including design, construction and flying characteristics. It also states that designers seeking a SAIL Mark must ask an RAE(F) to assess the UAS, after which the RAE(F) advises the CAA whether the requirements have been met. (Civil Aviation Authority)
That sounds reasonable until you look at what many drone manufacturers are actually building. A modern drone is typically assembled from radios, flight controllers, GPS receivers, batteries, transmitters, electronic speed controllers and other components that already sit within an established conformity framework. Radio equipment is already subject to applicable radio and EMC requirements. CE-marked products and components are already required to demonstrate compliance with applicable Union harmonisation legislation.
EASA’s own guidance for manufacturers confirms that drones are subject to legislation such as the
Radio Equipment Directive and Machinery Directive, and that manufacturers must demonstrate compliance through the defined conformity procedures before affixing CE marking. (EASA)
So the question the industry should be asking is simple: what additional safety value is actually being created by the RAE(F) process, and what is merely a re-check of paperwork that already exists?
The SAIL Mark system is described by the CAA as optional; CAP 722K explicitly states that there is “no obligation” for a UAS designer to SAIL mark their aircraft in the UK. However, the practical reality may become very different. If operators increasingly need SAIL marked aircraft to make UK SORA applications easier, then an “optional” scheme can quickly become a commercial necessity. Once that happens, manufacturers who cannot afford the cost, delay and administrative workload of SAIL Marking may find themselves excluded from parts of the market, even when their aircraft are built from compliant, traceable and already-certified components.
This is where the system becomes problematic. The RAE(F) does not replace proper engineering by the manufacturer. It does not design the aircraft. It does not manufacture the aircraft. In many cases, it will not add meaningful physical test data beyond what the manufacturer has already generated.
CAP 722K requires the designer to submit evidence data to the RAE(F), and the RAE(F) must verify the designer’s compliance against the agreed compliance basis and approach. That is fundamentally an evidence-review model.
Evidence review has value where the aircraft is novel, high-risk, complex, or where the manufacturer is claiming safety functions that are not already proven. But it is much harder to justify when the review becomes a costly confirmation that standard components meet standards they have already been tested against. For example, CAP 722K’s C3 link requirements require data such as C3 link performance, RF spectrum and environmental conditions, plus evidence that the remote pilot can monitor C3 link performance.
Those are important issues, but for many systems the underlying radio modules, output powers,
frequency bands and conformity evidence already exist. The danger is that the RAE(F) becomes an expensive intermediary between the manufacturer’s existing technical file and the CAA’s approval process.
The CAA’s own charging structure shows the wider cost environment that manufacturers and operators now face. For 2026/27, UK SORA-based Operational Authorisation charges range from £2,422 at SAIL 1 to £17,300 at SAIL 5 and SAIL 6, with additional assessment charges possible at £346 per hour. These are CAA charges, not necessarily the full commercial cost of engaging an RAE(F), but they demonstrate the direction of travel: higher SAIL means higher cost, more documentation, more assessment and more delay. (Civil Aviation Authority) EASA’s Design Verification Report system raises similar concerns. EASA states that DVR costs are based on actual time spent assessing documentation, charged at €250 per hour, and that the duration depends heavily on system complexity and the manufacturer’s responsiveness. Again, this is a documentation-heavy model that may be appropriate for higher-risk or more novel designs, but it risks becoming disproportionate when applied too broadly. (EASA)
The strongest argument for SAIL Marking is that it allows a manufacturer to prove the technical aspects once, so operators do not have to repeat the same evidence for every Operational Authorisation. That is a valid objective. The CAA itself says that as more SAIL-marked UAS become available, operators will be able to use them to comply with certain UK SORA technical requirements. (Civil Aviation Authority)
But that benefit only materialises if the process is quick, affordable, consistent and genuinely additive. If the system is slow, expensive and mostly duplicates existing component compliance, then it will not accelerate innovation. It will tax it.
This concern is not just theoretical. In consultation feedback submitted to the CAA, the Royal Aeronautical Society warned that limited numbers of organisations providing RAE(F) services could increase industry costs, extend authorisation timelines and limit growth. The same response noted that many UK drone manufacturers are SMEs, often developing products with limited revenue, and that overly burdensome regulation can make compliance expensive and time-consuming during the critical period before a product is commercialised.
That is the core issue. The UK drone industry is not made up only of large aerospace primes with dedicated certification departments. Much of the innovation comes from small manufacturers, engineering-led start-ups and specialist operators building practical systems for real-world use cases. These companies already face costs for product development, testing, insurance, manufacturing, software, documentation, operational approvals, training, export compliance and market access. Adding another expensive assessment layer may satisfy an administrative need, but it can easily become a barrier to entry.
There is also a risk of regulatory mismatch. Drone technology evolves quickly. Components change, firmware changes, radio modules change and payloads change. A certification-style model that works for traditional aviation can become misaligned with the pace of unmanned aircraft development. The more the approval system struggles to keep up with real product cycles, the more manufacturers will either delay innovation, avoid the UK market, or design around the approval process rather than around the best technical solution.
The answer is not to abandon safety assurance. The answer is proportionality.
For low and medium-risk SAIL levels, the CAA should allow more reliance on manufacturer declarations, existing CE/UKCA/RED evidence, component certificates, conformity documentation and controlled internal test reports. RAE(F) involvement should focus on genuinely operation-specific or system-level risks: containment, failure modes, command-and-control resilience, geofencing, flight termination, software behaviour and manufacturing consistency. It should not become a paid exercise in re-reading radio module certificates and checking that standard parts already comply with standards they were built to meet.
A better model would separate “paperwork already proven elsewhere” from “system-level flightworthiness claims.” If a manufacturer uses a compliant radio module within its rated power, frequency and environmental envelope, that should not need a full reassessment. If a manufacturer claims that its drone can safely terminate flight, contain itself within a defined volume, detect C3 degradation or maintain operational control in a swarm, then that is where independent assessment can add value.
The UK has an opportunity to build a sensible, risk-based drone approval system. But if RAE(F) and SAIL Marking become too expensive, too slow, or too focused on duplicating existing standards, the result will not be a thriving ecosystem. It will be a smaller market, fewer manufacturers, slower product development and less innovation.
The CAA may see the creation of the RAE(F) system as a step forward. For parts of the industry, it may well be. But unless the system is kept proportionate, transparent and affordable, it risks becoming exactly what manufacturers fear: an expensive double-check on compliant products, paid for by the very companies the UK needs if it wants to lead in unmanned aviation.

Guest post from Jared Oren, Test and Evaluation Division Director at the Science and Technology Directorate’s (S&T) National Urban Security Technology Laboratory (NUSTL).
Over the past several years, NUSTL has received more inquiries about drones than almost any other technology in our laboratory’s history. We’re seeing more and more cases of public safety agencies using small unmanned aircraft systems (sUAS) in their daily operations, from providing aerial situational awareness and enhancing physical protection to supporting search and rescue efforts. The practical use cases for this technology are growing, and America’s first responders are looking for insight into how this technology can improve their safety and effectiveness.
At NUSTL, we work closely with the public safety community to understand and address their most pressing issues. We host a range of working groups, such as the Big City Fire Working Group, that focus on emerging threats and opportunities impacting first responders across the nation. Given the increased interest in sUAS we’ve seen in recent years, the lab has prioritized research and operational assessments that provide first responders with information they need to determine which solutions best fit their mission needs.
One of the latest resources available is NUSTL’s Small Unmanned Aircraft System Program Documentation for Public Safety: Recommendations and Templates. This planning tool gives responders a comprehensive methodology to safely and effectively set up their own program: administrative, operational, qualifications and training, safety, and maintenance.
We created it with collaborative inputs from urban and rural first responders across the country who have experienced the challenges firsthand of how to quickly and effectively initiate or expand a drone program. We understand responders typically don’t come from an aviation background, and we wanted to provide them with a resource that helped fill that gap. The result is a streamlined, easy-to-use template that makes it simpler than ever for responder agencies to implement policies and procedures quickly and get to the real mission at hand – saving lives.
Several factors are driving the increased adoption of sUAS for public safety agencies. Like other technologies, UAS incorporate much of the same components as other popular electronics. Batteries, cameras, and radios are all present in laptops and phones, thus the cost of manufacturing has decreased over time, making them a more affordable option than in prior years. Changes to Federal Aviation Administration regulations have also simplified the process for Drone as First Responder operations, clearing the way for more agencies to incorporate sUAS capabilities into their duties. There is also a national emphasis on expanding America’s sUAS industry, which will ensure the solutions safeguarding our skies are developed by trusted manufacturers.
It comes down to this: UAS are going to play a bigger role in first responder operations moving forward, and agencies need a trusted expert to help them find the right solutions for their unique needs. S&T and NUSTL provide that expertise, giving responders actionable insight and resources that ensure they spend less time worrying about tech specs and more time focused on the mission. I encourage you to review the sUAS Recommendations and Templates to see how your program can benefit.
