Aviation industry leaders convened in San Diego on June 9, 2026, to outline a pragmatic approach to artificial intelligence, emphasizing the deployment of AI for customer service and logistics while intentionally excluding non-deterministic algorithms from flight-critical systems to maintain certifiability.

During a panel discussion at the American Institute of Aeronautics and Astronautics (AIAA) AVIATION Forum, representatives from United Airlines, Reliable Robotics, Collins Aerospace, and the National Aeronautics and Space Administration (NASA) detailed how advanced automation is currently utilized. According to reporting by Aerospace America, the consensus among panelists highlighted a shift away from abstract autonomy concepts toward solving immediate operational friction using classic software engineering for safety-critical applications.

Airline operations and customer management

For major commercial carriers, artificial intelligence is primarily a tool for managing scale and complexity on the ground. Roberta Zimmerman, Director of Air Traffic Strategy, Data Analytics, and Strategic Vision at United Airlines, detailed the operational volume the carrier manages, expecting 5,359 daily departures and offering over 700,000 daily seats across its network. The airline recently achieved a record of 630,500 passengers flown in a single day.

To support this volume, United Airlines utilizes AI to facilitate flight-by-flight customer communication. Zimmerman noted that the technology provides rebooking alternatives for passengers with delayed first legs and calculates predicted walking times between gates at connecting airports. She also cautioned that the national airspace is a complex system of systems, meaning even minor technological integrations require careful management to prevent any loss of operational continuity.

Certification hurdles for flight-critical systems

While airlines focus on passenger logistics, aerospace manufacturers and automation startups face strict regulatory barriers when applying AI to aircraft control. Reliable Robotics, which successfully demonstrated the remote piloting of an 8,000-pound Cessna Caravan from a distance of 50 miles in 2023, is targeting automated operations at approximately 2,000 US airports equipped with Localizer Performance with Vertical Guidance (LPV) capabilities.

Brandon Suarez, Vice President of Unmanned Aircraft Systems (UAS) Integration at Reliable Robotics, explained that using non-deterministic AI in flight-critical systems is currently unworkable for startups due to the lack of established certification standards. Instead, the company relies on traditional software coding languages and classic algorithms for aircraft automation. Suarez described the certification process as the task of convincing an objective expert that a system is correct, a standard that cannot be met if the software’s decision-making process cannot be explicitly explained.

Travis Klopfenstein, Innovation Program Manager at Collins Aerospace, echoed the necessity for explainable systems. He noted that securing funding and leadership approval requires transparent technology. Consequently, Collins Aerospace focuses on increasing automation to optimize human decision-making rather than pursuing full autonomy, while also developing low-criticality applications such as inventory management systems for aircraft galleys.

Establishing reliability standards

The challenge of certifying advanced automation extends to defining acceptable performance metrics. Chester Dolph, an engineer at the NASA Langley Research Center, highlighted that developers must be able to explicitly explain when and why a system works, as well as the specific conditions and reasons for its failure.

Anna Dietrich, an aviation consultant, pointed out the disparity between human and machine performance expectations. She observed that the aviation industry lacks a quantitative consensus on the reliability expected from human operators, who are afforded a margin for error that automated systems are not. Setting the acceptable performance bar for these new systems remains a primary challenge for regulators and developers alike.

AirPro News analysis

We observe a distinct maturation in how the aerospace sector discusses artificial intelligence. The dialogue has moved past the initial hype of fully autonomous passenger aircraft toward a bifurcated reality. On the ground, airlines are rapidly adopting AI to manage the staggering complexity of crew scheduling, irregular operations, and passenger logistics. In the air, manufacturers and startups are deliberately avoiding machine learning in flight control systems to ensure compliance with Federal Aviation Administration (FAA) certification frameworks. Until regulators establish clear, standardized methods for verifying non-deterministic software, we expect the industry will continue to rely on deterministic, classic coding for any system that directly affects safety of flight.

ProLogium Technology Co., Ltd. and Netherlands-based Elysian Aircraft BV signed a Memorandum of Understanding (MoU) on June 18, 2026, to jointly develop and integrate next-generation battery cells for commercial all-electric Electric-Aviation aircraft. The partnership targets pack-level energy densities between 320 and 420 watt-hours per kilogram (Wh/kg), a critical threshold for enabling regional zero-emission flights of up to 1,000 kilometers.

Announced via a joint press release from Taoyuan, Taiwan, and Paris, France, the agreement focuses on adapting ProLogium’s lithium ceramic battery technology for aviation applications. The collaboration will specifically support the development of the Elysian E9X, a planned 88- to 100-seat all-electric airliner designed to challenge conventional regional turboprops and narrowbody jets.

Advancing battery technology for the Elysian E9X

The MoU outlines a framework for rigorous assessment and validation of ProLogium’s next-generation cells within the demanding operational environment of commercial aviation. Aviation battery systems require significantly higher safety standards, weight efficiency, and energy density compared to automotive applications.

Elysian Aircraft BV has been refining the design of its E9X concept since its formal launch in January 2024. Following a conceptual design review completed in April 2026, the Manufacturers updated the aircraft’s specifications to feature six electric motors, a 50-meter wingspan to accommodate the battery packages, and a Maximum Take-Off Weight (MTOW) of 82.5 tonnes.

Rob Wolleswinkel, Co-Chief Executive Officer and Chief Technology Officer of Elysian Aircraft BV, emphasized the need for comprehensive ecosystem development alongside aircraft design.

“Battery technology is a key enabler for electric aviation, but aviation requires far beyond cell performance alone. As we advance our all-electric aircraft, the E9X, and the core electrification technologies, we are also working with suppliers and partners who can help shape the broader ecosystem for electric flight,” Wolleswinkel stated in the press release.

ProLogium expands beyond automotive markets

For ProLogium Technology Co., Ltd., the Partnerships represents a strategic expansion of its solid-state and lithium ceramic battery portfolio beyond the electric vehicle sector. The company recently announced plans to list on the Nasdaq through a merger, positioning its all-inorganic solid-state batteries for broader commercial applications.

The targeted pack-level energy density of 320 to 420 Wh/kg is intended to provide the Elysian E9X with a functional range of 750 to 1,000 kilometers. Achieving this density at the pack level, rather than just the cell level, remains one of the primary technical hurdles in electric aviation.

Vincent Yang, Founder and Chief Executive Officer of ProLogium, noted the stringent requirements of the aerospace sector.

“The development of next generation batteries is not only relevant to the electric vehicle industry, but also closely connected to the future of energy transition and new forms of mobility. Aviation applications place extremely high demands on battery energy density, safety, and weight efficiency, which is why careful and rigorous assessment and validation are essential,” Yang said.

The stated target of 320 to 420 Wh/kg at the pack level is highly ambitious. Current state-of-the-art aviation battery packs generally hover around the 200 to 250 Wh/kg mark. If ProLogium and Elysian can successfully validate and certify a pack exceeding 300 Wh/kg, it would represent a step-change in the viability of 90-seat electric aircraft.

We note that Elysian’s recent design revisions, which increased the E9X wingspan to 50 meters and MTOW to 82.5 tonnes, reflect the physical realities of integrating massive battery volumes. The reduction from eight to six motors also suggests a focus on simplifying propulsion integration and reducing overall system weight. The success of this MoU will likely hinge on ProLogium’s ability to scale its lithium ceramic technology while meeting the European Union Aviation Safety Agency (EASA) thermal runaway containment and crashworthiness standards.

Munich-based manufacturer VÆRIDION has secured more than 100 commitments for its all-electric Microliner aircraft following the successful completion of the program’s Preliminary Design Review (PDR) on June 11, 2026.

The milestone freezes the basic design of the nine-passenger commuter aircraft, allowing the engineering team to transition into detailed design and hardware fabrication. According to a company press release, the accumulation of over 100 commitments signals growing market confidence as VÆRIDION targets a 2027 first flight and commercial entry into service by 2030.

Engineering milestones and prototype development

The completion of the PDR marks a critical phase for the clean-sheet electric-aviation conventional takeoff and landing (eCTOL) aircraft. The Microliner features a glider-inspired wing design that integrates modular battery systems, paired with multi-engine, single-propeller propulsion.

With the preliminary design frozen, VÆRIDION is advancing toward building its first conforming prototype. The company has established a supply chain featuring several established aerospace manufacturers. Evolito will provide the electric propulsion systems, while MT-Propeller and GKN Aerospace are supplying key components. On April 23, 2026, VÆRIDION announced the selection of Garmin G600 TXi flight displays for the initial test aircraft, a decision Chief Technology Officer Markus Kochs-Kämper noted would meet the specific avionics requirements of the test campaign.

Industrialization and production targets

To support the transition from design to physical hardware, VÆRIDION has been expanding its physical footprint and capital reserves. On March 13, 2026, the company inaugurated its first manufacturing facility and test house at Oberpfaffenhofen Airport in Germany, occupying a site previously utilized by Lilium.

Chief Executive Officer Ivor van Dartel stated in April 2026 that the company was in execution mode and actively fundraising to contract the next stages of development. VÆRIDION has applied for development assistance through the European Union Innovation Fund, backed by the European Investment Bank, to support industrialization efforts at the Oberpfaffenhofen factory. The manufacturer is ultimately targeting a production rate of 40 to 50 aircraft per year.

Operational capabilities and certification path

The Microliner is designed to serve regional commuter routes with a maximum range of 400 kilometers under Instrument Flight Rules (IFR) conditions. The aircraft aims to provide zero-emission regional connectivity, a sector drawing increased attention from operators looking to reduce carbon footprints on short-haul networks.

VÆRIDION is working toward certification with the European Union Aviation Safety Agency (EASA). The regulatory approval process is scheduled to align with the company’s target of a 2030 entry into service.

Securing 100 commitments at the PDR stage provides VÆRIDION with crucial market validation as it enters the capital-intensive prototype fabrication phase. While the eCTOL market is less crowded than the electric vertical takeoff and landing (eVTOL) space, the technical challenges of battery energy density and weight remain significant hurdles for any electric regional aircraft.

We note that VÆRIDION’s strategy of partnering with established aerospace suppliers like Garmin and GKN Aerospace reduces some developmental risk compared to a fully vertically integrated approach. However, maintaining the timeline for a 2027 first-flight will depend heavily on the success of the company’s current fundraising rounds and the timely delivery of conforming components to the Oberpfaffenhofen facility.
