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.

On June 3, 2026, Israeli electric vertical takeoff and landing (eVTOL) manufacturer AIR announced a strategic partnership with U.S.-based Dynon Avionics. According to the company’s official press release, Dynon will serve as the exclusive avionics provider across AIR’s entire smart aircraft portfolio.

This collaboration bridges the gap between traditional general aviation and the emerging Advanced Air Mobility (AAM) sector. By adapting Dynon’s widely utilized SkyView HDX flight display system for electric powered-lift operations, AIR aims to streamline the piloting experience for its upcoming vehicles while relying on proven aerospace technology.

The integration agreement covers both the piloted AIR ONE, a two-seat personal eVTOL designed for private ownership, and the uncrewed AIR ONE Cargo, a heavy-lift unmanned aerial system (UAS) utilized by defense and logistics organizations.

Adapting Proven Avionics for Electric Flight

Rather than developing a proprietary flight display from scratch, AIR has opted to customize Dynon’s flagship SkyView HDX avionics platform specifically for its eVTOL architecture. Originally introduced in 2016 for experimental and light sport airplanes, the SkyView HDX system features touchscreens that combine a primary flight display, moving-map navigation, synthetic vision, autopilot, and ADS-B traffic and weather data.

Customizing for eVTOL Operations

Because the AIR ONE utilizes electric propulsion rather than a traditional piston engine, Dynon’s engineering team adapted the SkyView HDX to meet the unique demands of powered-lift flight. According to the release, the customized system tracks electric propulsion metrics and battery energy management, ensuring pilots have clear, intuitive access to critical flight data.

“SkyView HDX is built to adapt to evolving aircraft architectures. Partnering with AIR allows us to take the proven reliability of SkyView HDX, which pilots rely on daily, and extend it directly into the advanced air mobility space.”

AIR’s Path to Commercialization and Manufacturing

AIR is positioning itself uniquely within the AAM market by focusing on personal and cargo air mobility rather than commercial air taxi services. The company’s flagship product, the AIR ONE, is designed as a “flying sports car” for private owners. According to company specifications, the aircraft features a target range of 100 miles, cruise speeds up to 155 mph, and a payload capacity of 550 pounds.

Production and Financial Traction

The avionics partnership comes at a time of significant growth for the Israeli manufacturer. As of March 2026, AIR reported surpassing $1 billion in its order backlog. This figure represents over 3,300 waitlisted customers, including 3,290 reservations specifically for the AIR ONE personal eVTOL. Furthermore, the company stated it has already generated over $35 million in booked revenue, primarily driven by deliveries of its heavy-lift UAS variants.

To support this backlog, AIR transitioned to commercial-scale serial manufacturing in July 2025 by opening a 32,000-square-foot production facility in Pardes Hanna, Israel. The company notes that this facility is capable of assembling up to six aircraft simultaneously.

“From the start, AIR has focused on making advanced flight systems intuitive, safe, and accessible. Working with Dynon allows us to bring proven avionics capability into a fundamentally new aircraft environment that demands more than a standard integration, while keeping the simplicity and operational clarity that define how we think about flight.”

Regulatory Tailwinds: The FAA MOSAIC Rule

The timing of this avionics integration aligns closely with a major regulatory shift in the United States. The Federal Aviation Administration’s (FAA) Modernization of Special Airworthiness Certification (MOSAIC) rule, finalized in July 2025, fundamentally changes how personal aircraft are certified.

Certification Timeline

Previously, Light Sport Aircraft (LSA) regulations excluded powered-lift aircraft and enforced strict weight limits. The MOSAIC rule removes these prescriptive weight limits in favor of performance-based metrics, officially allowing powered-lift aircraft like eVTOLs to be certified in the LSA category. While pilot privileges under MOSAIC took effect in October 2025, the new aircraft certification provisions for manufacturers take effect on July 24, 2026. AIR expects the FAA to approve the AIR ONE under these new rules this year, enabling the company to begin fulfilling its U.S. backlog.

AirPro News analysis

We view this partnership as a prime example of traditional general aviation technology successfully pivoting to support the booming AAM sector. It demonstrates that eVTOL manufacturers do not necessarily need to reinvent the wheel regarding cockpit displays; they can adapt proven, trusted systems to save on development costs and certification hurdles. Furthermore, by integrating a familiar system like Dynon’s SkyView HDX, AIR is strategically lowering the barrier to entry for existing private pilots transitioning to electric aircraft. Finalizing its supply chain and technology stack just ahead of the July 2026 MOSAIC implementation positions AIR favorably to capitalize on the emerging personal eVTOL market.
