On June 8, 2026, Honeywell Aerospace showcased its “Copper Bird” advanced flight demonstrator at its Deer Valley campus in North Phoenix, Arizona, providing a ground-based testing and demonstration platform for next-generation electric vertical takeoff and landing (eVTOL) aircraft systems.

Detailed in an official company publication, the Copper Bird serves as a fully integrated testbed for Advanced Air Mobility (AAM) technologies. The platform allows engineers, industry partners, and investors to validate the complete “stick-to-surface” all-electric control chain without leaving the ground. The name adapts the traditional aerospace “iron bird” concept, substituting “copper” in recognition of Arizona, the Copper State, where Honeywell Aerospace is headquartered.

Integrating the all-electric control chain

The demonstrator brings together several of Honeywell’s core AAM products into a single functional cockpit environment. Key integrated systems include the Honeywell Anthem flight deck, the company’s Compact Fly-By-Wire system, and Honeywell Assure electromechanical actuators.

By linking these components, the Copper Bird translates complex electronic processes into a tangible experience. Phil Robinson, Chief Technology Officer for Advanced Air Mobility at Honeywell Aerospace, described the setup as a critical tool for visualizing system integration.

“The Copper Bird is a real-time integrated aircraft testbed and ‘show and tell’ platform that demonstrates the complete stick-to-surface, all-electric control chain in one place,” Robinson stated.

Partner validation and public acceptance

The facility is actively used by conventional aircraft manufacturers and AAM developers to test system responses in simulated real-world conditions. Vertical Aerospace is among the partners that have piloted the demonstrator to evaluate the scalable Honeywell Anthem system, which is designed to support commercial air transport, business aviation, and military applications alongside the emerging eVTOL sector.

Jacob Maxfield, Senior Offering Manager for the Honeywell Aerospace AAM team, noted that the platform proves the maturity of the company’s hardware and software. Guests can sit in the cockpit and fly the system to observe how an aircraft would respond to control inputs.

“It allows us to demonstrate how our flight control computers, actuators, inceptors and displays are fully integrated, mature and ready to support next generation aircraft,” Maxfield said.

Robinson also emphasized the importance of the demonstrator in building public trust, noting that people need to see the company applying the same rigor and safety standards to AAM as it does to traditional aircraft.

AirPro News analysis

We view the Copper Bird as a strategic asset for Honeywell Aerospace as it competes for market share in the crowded AAM supplier ecosystem. While individual components like electromechanical actuators and fly-by-wire computers are critical, the ability to demonstrate a unified system architecture provides a distinct advantage when courting eVTOL startups. Many of these new entrants lack the legacy systems integration experience of traditional airframers. By offering a pre-integrated package, Honeywell reduces the development risk and certification burden for its partners. This ground-based validation is essential for building regulator confidence before these novel aircraft transition to flight testing.

Safran Electrical & Power released a video presentation on June 23, 2026, detailing the OSYRYS project, a European consortium aiming to develop electrical and thermal systems for the first hybrid-electric regional aircraft by 2035.

The project, coordinated by Safran as part of the Clean Aviation Joint Undertaking (CAJU), brings together 24 industrial and academic partners from nine countries. According to the company’s press release, the initiative is designed to reinvent energy management systems to achieve a 30 percent reduction in carbon dioxide emissions compared to 2020 state-of-the-art technology.

The Ultra-Efficient Regional Aircraft initiative

OSYRYS (On-board SYstems Relevant for hYbridization of Regional aircraftS) operates as one of four interrelated projects under the Ultra-Efficient Regional Aircraft (UERA) umbrella. The other three projects include HERACLES for aircraft concept development led by ATR, DEMETRA for flight demonstration also led by ATR, and PHARES for hybrid-electric propulsion led by Pratt & Whitney Canada.

The four consortia officially launched during joint meetings in Brussels, Belgium, in January 2026. The collaborative effort is supported by €140 million in funding from Clean Aviation, complemented by €200 million in in-kind contributions from the participating organizations over a five-year period.

Technical objectives and system architecture

The OSYRYS project specifically targets the development of electrical power generation, power distribution, thermal management, and avionics tailored for energy management. These systems are foundational for the transition to hybrid-electric propulsion in the regional aviation sector.

“OSYRYS is a crucial project for the Regional stream in Clean Aviation, providing paramount power distribution and cooling solutions for the hybrid-electric flight demonstration platform and the next Ultra Efficient Regional Aircraft expected to enter into service in the next decade,”

The statement above was provided by Jaime Perez De Diego, Project Officer for the Clean Aviation Joint Undertaking, during the project’s formal launch phase.

We view the 2035 entry-into-service target for a hybrid-electric regional aircraft as ambitious but structurally supported by the parallel development approach of the UERA projects. By separating the airframe, propulsion, flight demonstration, and internal systems into distinct but coordinated workstreams, the European aviation sector is mitigating the integration risks typically associated with clean-sheet hybrid designs. The success of OSYRYS will largely depend on the consortium’s ability to manage the significant weight penalties inherent in advanced thermal cooling and high-voltage power distribution systems.

The National Aeronautics and Space Administration (NASA) has detailed the role of its Experimental Fabrication Branch at the Armstrong Flight Research Center in accelerating the development of autonomous flight technologies and advanced Commercial-Aircraft components.

In a feature published on June 22, 2026, the agency highlighted how the Edwards, California-based facility serves as a full-service Manufacturing, modification, and repair center for its fleet of research and science aircraft. By integrating engineering and fabrication early in the design process, the branch shortens development timelines and minimizes design-to-hardware mismatches, supporting broader advancements in aviation safety, efficiency, and sustainability.

Advancing autonomous air taxi research

A primary focus of the facility’s recent work involves the Airborne Instrumentation for Real-world Video of Urban Environments (AIRVUE) sensor pod. The Experimental Fabrication Branch converted digital designs into a fully functional physical structure for the pod, which underwent testing to meet strict safety requirements prior to deployment.

The AIRVUE pod gathers video, laser range finding, and other flight data to populate a comprehensive dataset of actual flight scenarios. According to project details, this dataset is designed to assist developers of electric air taxis in training their aircraft to fly autonomously using onboard Software. NASA concluded the initial phase of the AIRVUE video archive project on December 16, 2024, under the direction of lead researcher Nelson Brown.
