AIR partners with Dynon Avionics to customize SkyView HDX for its eVTOL aircraft, targeting FAA certification in 2026.
This article is based on an official press release from AIR via PR Newswire.
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.
