Her session, ‘The UK Civil Aviation Authority’s hydrogen challenge,’ takes place on 29 September 2026 in the Testing Forum. Here, Leadbetter talks about the regulatory and certification gaps facing hydrogen propulsion, the safety challenges unique to hydrogen fuel, and why she believes commercial hydrogen aviation by 2035 remains achievable.

Pierre-Alain Goujard, Flight Operations Lead at Helsing, will present ‘Testing as they fight: how to navigate European Drone test centres to deliver battlefield-grade capabilities’ at the Defence Testing Forum on 30 September 2026. His presentation will examine the challenges of flight-testing defence drones that must operate according to military requirements in war zones while remaining compliant with civilian regulation during development. Goujard argues that conventional regulatory pathways are not sufficient for this task, requiring instead a combination of suitable flight areas, effective links with military and civilian authorities, and patience. Goujard will also take part in the panel discussion ‘Integrating UAS & Counter-UAS into the Modern Battlespace: Interoperability, Open Architecture & Manned–Unmanned Teaming’, also on 30 September 2026. Ahead of the event, he discusses what genuine integration could look like, the barriers to interoperability, the evolution of counter-UAS systems, and why open architectures and software-defined capabilities will be critical to future defence operations.

He will also deliver a presentation, ‘How standards are supporting new types of aircraft,’ in the Testing Forum on the same day, explaining how industry standards complement the regulatory and certification framework, and how current work on VTOL, hydrogen and hybrid-electric propulsion is supporting emerging aviation technologies. Here, Riveill talks about how EUROCAE’s consensus standardisation process works, the latest progress across its key working groups, and the growing crossover between advanced air mobility and military applications.

Vaeridion will take to the Future Propulsion Forum on 29 September 2026 for the session ‘An Alternative to Distributed Propulsion: Vaeridion's Multi-Engine Single-Propeller Approach.’ The company's patented multi-engine, single-propeller electric propulsion system combines the redundancy of a twin-engine architecture with the operational safety of centreline thrust, while avoiding the complexity of gearboxes and/or contra-rotating propellers. The presentation will explore the design principles behind the architecture, the key trade-offs that shaped it, and the early steps taken to de-risk certification, as well as highlighting how the approach is uniquely aligned with the operational and performance requirements of the Vaeridion Microliner. Here, Douglas Costa, head of propulsion and systems at Vaeridion, talks about the thinking behind the architecture, the certification journey so far, and what's next for the technology.

AURA AERO is applying the agility and technology built through its civil aircraft programmes to develop scalable, sovereign platforms for the defence sector, according to Jérémy Caussade, co-founder, president and chief engineer of the company. Caussade co-founded AURA AERO in 2018 alongside Wilfried Dufaud and Fabien Raison, with the ambition of designing electric and hybrid aircraft that are both high-performing and environmentally friendly. The company’s two-seater Integral, built for training and aerobatics, marked its first milestone, while the 19-seater ERA (Electric Regional Aircraft) is due to make its maiden flight in 2027. Caussade will outline the company’s strategic vision for defence at the Aerospace Test & Development Show 2026. His session, ‘AURA AERO: A Strategic Vision for Defence,’ takes place on 30 September 2026 in the Defence Testing Forum. Here, Caussade talks about how AURA AERO’s civil aviation technology transfers to military applications, why sovereignty is central to its strategy, and the role electric and hybrid propulsion could play in future defence platforms.

Freshta Farzam, CEO and Founder of LYTE Aviation, will present ‘Is a 40-seater hybrid hydrogen eVTOL realistic with today’s tech?’ at the Future Propulsion Forum during the Aerospace Test & Development Forum on 29 September 2026. The presentation will explore LYTE Aviation’s LA-44, a 40-seat hybrid-hydrogen eVTOL designed for regional passenger transport and heavy cargo operations. With a claimed 600-mile range and 4.5-tonne payload, the aircraft represents a significant departure from the low-payload, short-range eVTOLs currently dominating the advanced air mobility market. Farzam will discuss the aircraft’s tandem tilt-wing configuration, hybrid propulsion system combining SAF-powered turboprops with hydrogen fuel-cell electric engines, and the roadmap towards certification and commercial operation. Ahead of the event, she discusses why LYTE Aviation chose to pursue a larger aircraft from the outset, the technology behind the LA-44, its potential efficiency advantages, certification challenges, and the company’s ambitions for commercial operations from 2032.

The increasing use of ‘system-of-systems’ (SoS) concepts, unmanned aerial systems (UAS), autonomy and AI is changing the way defence capabilities are developed and tested, according to Thomas Grohs, Head of Unmanned Aerial Systems at Airbus Defence and Space. On 30 September, Grohs will present on the changing test and verification landscape at the Defence Testing Forum during the Aerospace Test & Development Show 2026. His presentation, ‘Testing in the Age of System of System, UAS, Autonomy and AI’, will examine the links between operational needs, product solutions and the associated test and verification requirements. As defence forces seek to adapt more quickly to an evolving threat environment, Grohs highlights SoS concepts, faster development cycles for unmanned systems, and software-driven functionality in areas such as autonomy and AI as key elements of this shift. Here, Grohs discusses why SoS approaches are becoming increasingly important, how unmanned systems change development and testing, and why Live, Virtual and Constructive environments, simulation and digital verification will play an important role in future defence testing.
