This article is based on an official press release from Eve Air Mobility.

Eve Air Mobility (NYSE: EVEX), a global leader in advanced air mobility and a spin-off of Brazilian aerospace manufacturer Embraer, has successfully concluded the hover and low-speed flight test block for its full-scale electric vertical takeoff and landing (eVTOL) engineering prototype. The completion of this phase marks a critical milestone in the aircraft’s development, generating high-fidelity data that validates the company’s aerodynamic models and control laws.

According to the company’s press release, this testing phase was designed to expand the flight envelope step-by-step. By validating models and aircraft behavior against real-world data before advancing to more complex maneuvers, Eve is laying a disciplined technical foundation. The successful closeout of these low-speed tests clears the path for the highly anticipated transition flight testing phase, which is expected to commence in the summer of 2026.

Backed by Embraer’s 55 years of aviation certification expertise, Eve has adopted a methodical, building-block approach to its flight test campaign. This strategy aims to tighten the correlation between simulation predictions and actual flight behavior, ensuring safety and reliability as the program advances toward commercial certification and entry into service.

Flight Test Achievements and Performance Metrics

Pushing the Low-Speed Envelope

The recently completed test block yielded significant operational data. According to the official release and supplementary program data, the uncrewed prototype completed 59 flights, accumulating a total of 2 hours, 27 minutes, and 33 seconds of flight time. During these tests, the aircraft reached a maximum altitude of 215 feet above ground level (AGL) and achieved a maximum single-flight duration of 3 minutes and 48 seconds.

Testing initially focused on a low-speed input phase below 15 knots to validate control laws, downwash effects, thermal behavior, and the propulsion model. As the campaign progressed, operations expanded to approximately 20 knots of ground speed. During this expanded envelope, the engineering team successfully executed simultaneous four-axis maneuvers, which are crucial for validating aerodynamic and load models under dynamic conditions.

System Validations and Firsts

Beyond basic flight metrics, the test block included several notable technical demonstrations. Eve reported the successful execution of more than 100 specific flight test points. Crucially, the aircraft demonstrated its autoland capabilities and a “simplified fly-by-wire mode” for the first time. This simplified mode serves as a secondary, backup layer of the flight control system, designed to activate if the normal fly-by-wire mode becomes unavailable.

The company also noted that recorded noise levels remained in line with expectations, while both battery and propulsion performance exceeded initial projections.

“Completing hover and low‑speed testing gives us high‑confidence data to validate and refine our aerodynamic, propulsion and load models. That model correlation is what enables disciplined envelope expansion. With planned ground tests next, we will be ready to begin transition flights, in which we validate the lifter-pusher synchronization before moving on to the cruise phase.”

Marcelo Basile, Head of Tests at Eve Air Mobility

The Road to Transition Flights

Preparing for Summer 2026

With the hover and low-speed block complete, Eve’s engineering prototype will now undergo a series of planned ground tests. These tests are a prerequisite for the transition flights block, which the company expects to begin in July or August of 2026. The transition phase will focus on expanding the flight envelope further, specifically validating the synchronization between the vertical lifting rotors and the rear pusher propeller as the aircraft shifts to wing-borne forward flight.

“Closing this phase validates the discipline behind our flight test strategy. Across 59 flights, we confirmed stable hover performance and predictable control behavior within the envelope, while expanding our understanding of loads, aerodynamics, propulsion and energy management, key foundations for the transition phase and the certification path ahead with the conforming prototypes.”

Johann Bordais, CEO of Eve Air Mobility

Aircraft Design and Market Position

Lift + Cruise Configuration

Eve’s eVTOL utilizes a “Lift + Cruise” configuration. The design features eight dedicated fixed-pitch rotors for vertical lift and a rear pusher propeller for forward cruise flight, all supported by fixed wings. By eliminating complex tilting mechanisms, the company aims to prioritize safety, mechanical reliability, and a more straightforward certification path.

The 100% electric aircraft is designed to carry four passengers and one pilot at launch, with a targeted range of 100 km (60 miles). This range is optimized for high-frequency urban air mobility (UAM) routes. Future iterations of the aircraft are planned to accommodate up to six passengers once autonomous, uncrewed operations are certified.

Industry-Leading Backlog and Ecosystem

Eve Air Mobility benefits heavily from its relationship with Embraer, which remains the majority shareholder with an approximate 70% stake. This backing provides Eve with access to over 800 contracted engineers and a global service center network.

This robust corporate foundation has translated into significant market confidence. Eve currently holds the largest customer order backlog in the UAM industry, boasting letters of intent for approximately 2,800 aircraft, representing a potential $14 billion in revenue. Furthermore, the company is developing a comprehensive UAM ecosystem, including Eve Vector (urban air traffic management software) and Eve TechCare (aftermarket services).

AirPro News analysis

We observe that Eve Air Mobility is playing a strategic “tortoise and hare” game within the broader eVTOL sector. While competitors such as Joby Aviation and Archer Aviation have already pushed through to transition flights, Eve has deliberately adopted a more incremental, simulation-heavy approach. By leveraging Embraer’s deep institutional knowledge of aviation certification, Eve is prioritizing model correlation over rapid physical milestones.

The upcoming Summer 2026 transition phase represents the ultimate engineering hurdle. Transitioning from vertical rotor lift to wing-borne aerodynamic lift involves passing through a complex, low-speed “grey zone.” Successfully navigating this phase will be a massive de-risking event for the company and its investors. Despite being slightly behind some rivals in physical flight testing timelines, Eve’s methodical strategy, coupled with its industry-leading backlog of 2,800 aircraft, suggests that the market values certification certainty and manufacturing pedigree just as highly as early test flight footage.

Airbus A380 Flight Lab Unveiled for CFM RISE Open Fan Testing

Airbus and CFM International unveil A380 flight lab livery at Farnborough 2026 for CFM RISE Open Fan engine tests.

Published

on

Airbus SE and CFM International unveiled the livery for the Airbus A380 flight lab dedicated to testing the CFM RISE (Revolutionary Innovation for Sustainable Engines) Open Fan engine architecture at the Farnborough International Airshow on July 21, 2026.

The presentation coincides with the completion of the first conceptual flight test design review. The joint program between Airbus and CFM International, a 50/50 joint company between GE Aerospace and Safran Aircraft Engines, aims to reduce fuel consumption and carbon dioxide emissions by 20 percent compared to current commercial engines.

Transitioning to flight test preparation

The designated testbed aircraft, an Airbus A380 identified as Manufacturer Serial Number (MSN) 114, departed a six-year desert storage in France on July 16, 2026. The aircraft relocated to Shannon, Ireland, to undergo painting and structural modifications. Engineers will eventually mount the open fan engine in the number 2 position on the inboard left wing for the Test-Flights campaign.

CFM International recently completed the preliminary design review for the compact core system, open fan, and outlet guide vanes. Arjan Hegeman, Vice President of Future of Flight Engineering at GE Aerospace, stated that this milestone allows the Manufacturing of parts for the grounded demonstrator to begin.

Prioritizing engine durability

While the open fan design removes the traditional engine casing to accommodate a larger fan and reduce drag, program leaders are placing equal emphasis on component longevity. GE Aerospace has completed over 350 tests and 3,000 endurance cycles on core components, which includes early dust ingestion testing.

“If there’s anything we’ve learned over the last years, it’s that durability matters as much as, if not more than, fuel efficiency,” Hegeman said.

Hegeman noted that the engineering teams are aiming to reach technology readiness level six by the turn of the decade.

AirPro News analysis

The explicit focus on durability during the early testing phases of the CFM RISE program reflects a broader industry shift. Current-generation narrowbody engines have faced well-documented time-on-wing and maintenance challenges, prompting Manufacturers to prioritize robust operating characteristics alongside fuel efficiency gains. By subjecting core components to 3,000 endurance cycles and dust ingestion tests years before the first flight, CFM International is working to ensure the open fan architecture can withstand harsh operational environments from entry into service. We expect this dual mandate of efficiency and reliability to define the Certification pathway for next-generation Propulsion systems.

The joint venture will operate across locations in Santa Cruz, California, and Toyota City, Japan.

Joint venture structure and financial stakes

Toyota holds a 51 percent majority stake in the new manufacturing company, acquired through the purchase of 1.02 million shares for $1.02 million. Joby retains the remaining 49 percent stake, having purchased 980,000 shares for $980,000. The joint venture will be governed by a five-member board of directors, with three members designated by Toyota and two designated by Joby.

The agreement includes specific intellectual property licensing arrangements between the two parent companies. Joby will license certain aircraft-related intellectual property to the joint venture on a royalty-free basis. In return, Toyota will license manufacturing-related intellectual property to the venture, which includes certain royalty-bearing rights.

Scaling eVTOL production

The formal joint venture builds upon a foundation of significant financial and technical support from the Japanese automaker. Toyota has provided approximately $900 million in total capital to Joby to date. The automaker is already providing technical assistance as Joby establishes a series production line for the S4 eVTOL aircraft at a facility in Ohio.

In the June 30 press release, Joby Aviation founder and CEO JoeBen Bevirt highlighted the depth of the corporate relationship.

“Toyota has been by Joby’s side for nearly a decade, providing invaluable guidance and support as we built the foundation for Manufacturing our aircraft. Today’s announcement reflects the strength of our relationship and our shared confidence in the opportunity ahead.”

Toyota Motor Corporation Chairman Akio Toyoda stated that the company views air mobility as a natural extension of its philosophy of providing mobility for all, expanding its focus from the ground into the sky to bring new value to society.

Certification progress and next steps

The manufacturing alliance aligns with Joby’s ongoing Certification efforts with the U.S. Federal Aviation Administration (FAA). During the first quarter of 2026, Joby began flying its first FAA-conforming aircraft for type inspection authorization. This testing phase is a required step as the company works toward achieving full FAA type certification for the S4 Series.

With the joint venture now legally established, the two companies will begin integrating their engineering and manufacturing teams across the California and Japan facilities to prepare for high-volume aircraft production.

AirPro News analysis

We view the formalization of the Joby Toyota Aero Manufacturing Preparation Company as a critical de-risking event for Joby’s production ambitions. While designing and certifying an eVTOL aircraft presents significant regulatory hurdles, manufacturing these vehicles at scale with automotive-style efficiency is an entirely different challenge that has historically troubled aerospace Startups. By securing a majority-stake commitment from Toyota, Joby gains direct access to one of the world’s most proven manufacturing systems. Furthermore, the intellectual property arrangement, where Toyota retains royalty-bearing rights on its manufacturing processes, suggests the automaker sees long-term revenue potential in aerospace production beyond its initial capital Investments.

KBR Selected for Asia’s First Ethanol-to-Jet SAF Plant in Singapore

KBR will provide PureSAF technology licensing and FEED services for a 100,000-ton/year SAF facility on Jurong Island, Singapore.

Published

on

On June 29, 2026, KBR announced its selection by Keppel Ltd. and Aster Chemicals and Energy to provide technology licensing and Front-End Engineering Design (FEED) services for a proposed 100,000-ton-per-year SAF (SAF) facility on Jurong Island, Singapore.

The planned facility is envisioned as Asia’s first commercial-scale ethanol-to-jet (EtJ) SAF plant. According to the KBR press release, the project will utilize the company’s PureSAF technology to produce a 100% drop-in jet fuel, supporting Singapore’s national mandate to increase sustainability usage across the aviation sector.

PureSAF technology and project scope

The Jurong Island facility will leverage PureSAF, a technology originally developed by Swedish Biofuels AB and engineered for commercial-scale production by KBR, which holds the exclusive global license. The process is designed to convert ethanol into aviation fuel that requires no blending with conventional Jet A or Jet A-1 before use.

In a statement accompanying the announcement, KBR President and CEO Stuart Bradie highlighted the system’s flexibility.

“KBR’s PureSAF is a feedstock-flexible, bankable technology that is designed to deliver a 100% drop in jet fuel, ready to power aircraft without blending. We are constantly innovating our SAF solution to make it compatible with feedstock availability in different regions and to enable the aviation industry to transition to low-carbon jet fuel with a cost-optimized approach.”

The FEED study will determine the technical configuration and project capital expenditure required for the facility. The development remains subject to regulatory approvals and a final investment decision (FID) by the project partners.

Aligning with Singapore’s aviation mandates

The selection of KBR follows a January 28, 2026, agreement between Keppel’s Infrastructure Division and Aster to jointly assess the development of the Jurong Island site. Aster operates as a joint venture between Indonesian petrochemical company Chandra Asri and Swiss commodities trader Glencore.

The proposed 100,000-ton annual production capacity aligns directly with targets set by the Civil Aviation Authority of Singapore (CAAS). Starting in 2026, the CAAS mandates a 1% SAF uplift for all departing flights from the country, with a stated goal of increasing that requirement to between 3% and 5% by 2030.

Alongside the SAF plant contract, KBR and Keppel signed a Memorandum of Intent to collaborate on broader energy transition initiatives. The companies plan to explore technologies related to waste-to-energy, plastic recycling, biofuels, and artificial intelligence-driven digitalization.

AirPro News analysis

We view the progression of the Jurong Island project to the FEED stage as a critical indicator of the Asia-Pacific region’s readiness to scale SAF production. While North America and Europe have led early SAF capacity investments, Singapore’s firm regulatory mandate provides the demand certainty required to underwrite commercial-scale facilities in Southeast Asia. The choice of an ethanol-to-jet pathway is particularly notable, as it allows operators to bypass the constrained supply of fats, oils, and greases that limit hydroprocessed esters and fatty acids (HEFA) production volumes. The project’s ultimate realization hinges on the upcoming final investment decision, which will test the commercial viability of the EtJ process in the current economic environment.
