Airbus Validates Wake Energy Retrieval in Transatlantic Flight Trials
Airbus and partners demonstrate Wake Energy Retrieval, showing potential 5% fuel savings in transatlantic trials with 75% success rate.

This article is based on an official press release from Airbus and the SESAR Joint Undertaking.
Airbus and Partners Validate “Wake Energy Retrieval” Operations in Transatlantic Trials
On February 25, 2026, Airbus and a consortium of airline and air traffic management partners announced significant progress in the effort to reduce aviation emissions through biomimicry. The GEESE (Gain Environmental Efficiency by Saving Energy) project has successfully validated the operational procedures required for Wake Energy Retrieval (WER), a technique designed to save up to 5% in fuel consumption on long-haul flights.
According to the official announcement from Airbus, the milestones were achieved during a series of transatlantic flight trials conducted in late 2025. These trials demonstrated that commercial aircraft can be reliably paired in mid-flight to fly in formation, mimicking the energy-saving V-formation used by migrating geese. The project focuses specifically on the Air Traffic Management (ATM) challenges of coordinating such maneuvers without disrupting standard airspace operations.
The successful validation of these procedures marks a critical step toward commercial deployment, proving that existing navigation technology and new coordination tools can bring two independent aircraft to a precise rendezvous point in the middle of the ocean.
Trial Results: Precision and Potential Savings
The recent trials involved eight specific flights over the North Atlantic, designed to test the feasibility of guiding two aircraft from different departure points to a single geographic location at the exact same time. Airbus reports that the trials achieved a 75% success rate, with the aircraft reaching their designated rendezvous positions as scheduled.
While these specific trials maintained vertical separation, meaning the aircraft flew at different altitudes for safety reasons, data analysis projected the efficiency gains that would have occurred had the aircraft engaged in actual formation flying.
“Data analysis revealed that if the six successful pairings had engaged in actual Wake Energy Retrieval… they would have saved a total of 12 tonnes of fuel.”
This equates to approximately 2 tonnes of fuel saved per flight. The concept relies on a “follower” aircraft positioning itself approximately 1.5 to 2 nautical miles (3 km) behind a “leader” aircraft. In this position, the follower rides the smooth updraft of air, or wake, created by the leader, generating “free lift” that allows the trailing aircraft to reduce engine thrust.
The Four-Step Coordination Process
A primary goal of the GEESE project is to establish a safe, repeatable process for Air Traffic Control (ATC) and airlines to manage these pairings. The trials validated a four-step operational workflow:
- Trajectory Computation: The Airbus Pairing Assistance Tool (PAT) calculates optimized flight paths and rendezvous instructions in real-time.
- Operational Assessment: Dispatchers, flight crews, and ATC centers review the proposed trajectories to ensure they meet all safety and operational standards.
- Visibility & Monitoring: A dedicated interface at the EUROCONTROL Innovation Hub allows all stakeholders to monitor the status of the pairing decision.
- Commitment: Flight crews activate a cockpit function to “commit” to the rendezvous, adjusting speeds to ensure simultaneous arrival at the meeting point.
This process confirmed that the Pairing Assistance Tool (PAT) can effectively guide aircraft to a merge point while maintaining standard safety protocols.
AirPro News Analysis
The GEESE project represents a shift in how the aviation industry approaches efficiency. Historically, fuel savings have been driven by hardware improvements, lighter materials and more efficient engines. Wake Energy Retrieval, however, is a software and operations-driven solution.
Achieving a 5% reduction in fuel burn without modifying the airframe or engines is substantial. For context, a typical engine upgrade on a widebody aircraft might yield a 10-15% improvement but requires billions in development and years of certification. A 5% gain purely through formation flying offers a complementary “operational upgrade” that could be deployed alongside new engine technologies. The challenge remains regulatory: moving from vertically separated trials to actual close-formation flying (1.5nm separation) will require rigorous safety cases to satisfy global aviation authorities.
Project Background and Partners
The GEESE project is an evolution of Airbus’s earlier “fello’fly” demonstrator, which focused on the aerodynamics and flight control systems required for formation flying. GEESE expands this scope to address the logistical challenge of integrating these formations into global air traffic.
The collaboration involves a wide range of industry stakeholders, including:
- Lead: Airbus
- Airlines: Air France, Delta Air Lines, French bee, Virgin Atlantic
- Air Navigation Service Providers (ANSPs): AirNav Ireland, DSNA (France), NATS (UK), EUROCONTROL
- Technology Partners: Indra, ENAC, CIRA, DLR, Frequentis, Boeing
Airbus has stated that the project targets full commercial deployment by the mid-next decade. The next phase of development will focus on regulatory approval to allow aircraft to fly at the same altitude with reduced separation, a prerequisite for realizing the fuel savings demonstrated in the simulations.

FAA Grants First eVTOL Market Survey Certificate to BETA Technologies
BETA Technologies receives the first FAA market survey authorization for an eVTOL aircraft, the ALIA A250, ahead of full type certification.

The Federal Aviation Administration (FAA) has granted BETA Technologies a Special Airworthiness Certificate for market surveys for its ALIA VTOL (A250) aircraft, marking the first time an electric vertical takeoff and landing (eVTOL) aircraft has received this specific authorization.
Announced in a company press release on October 21, 2026, the certification allows BETA to conduct flight operations with prospective customers, operators, and stakeholders. The authorization expands the geographic scope of the manufacturer’s operations and represents a regulatory milestone toward full type certification and commercial adoption in the Advanced Air Mobility (AAM) sector.
Inaugural flight and operational scope
On October 20, 2026, BETA conducted the first flight under the new authorization. The A250 aircraft departed from Plattsburgh International Airport (PBG) in New York and landed at Patrick Leahy Burlington International Airport (BTV) in Vermont. The flight covered a distance of 34 nautical miles and lasted 20 minutes.
Kyle Clark, Founder and Chief Executive Officer of BETA Technologies, stated that the authorization brings vertical flight closer to practical application and builds on the company’s previous testing milestones.
“Operators can now experience the VTOL firsthand and begin planning how it fits into their businesses, from connecting communities to moving people and goods at a lower cost,” Clark said. “This is an important step toward commercial adoption, and we’re grateful to the FAA for developing the regulatory framework that makes these operations possible.”
U.S. Transportation Secretary Sean P. Duffy called the certification a critical step toward enabling the future of flight in the United States. FAA Administrator Bryan Bedford emphasized the agency’s commitment to integrating new aircraft into the national airspace while maintaining rigorous safety standards.
Aircraft specifications and testing history
The ALIA VTOL (A250) is an all-electric aircraft featuring dual pilot controls. It is designed to accommodate up to five passengers and carry a minimum of 1,200 pounds of cargo. The A250 shares a common architecture, flight control computers, batteries, and propulsion systems with BETA’s conventional takeoff and landing aircraft, the ALIA CTOL (CX300).
BETA previously secured a similar market survey authorization for the CX300. Combined, the manufacturer’s CTOL and VTOL platforms have accumulated more than 250,000 nautical miles of flight time. The company completed the first crewed electric VTOL transition flight in 2024.
Expanding integration and emergency response testing
The market survey authorization follows a series of operational demonstrations by BETA Technologies. On October 7, 2026, the company completed operations in the Utah eVTOL Integration Pilot Program (eIPP), focusing on radiopharmaceutical delivery and treatment support.
Prior to that, on September 24, 2026, BETA partnered with Metro Aviation and Washington County EMS to fly an electric aircraft in an emergency response demonstration in Texas. The FAA and the U.S. Department of Transportation have selected BETA to participate in seven of the eight eIPP programs alongside government and operator partners. According to the company, this represents the highest participation rate of any original equipment manufacturer (OEM) in the initiative.
Regulatory pathway and market context
The FAA issued the Special Airworthiness Certificate for market surveys under Part 21 of its regulations. This framework allows manufacturers to demonstrate aircraft capabilities to potential buyers and operators before achieving full type certification.
BETA Technologies (NYSE: BETA), headquartered in South Burlington, Vermont, designs and manufactures electric aircraft alongside advanced electric propulsion and charging systems. The company is currently working toward full FAA type certification and commercial operations for the A250. The ability to conduct customer demonstration flights is intended to accelerate market adoption within the broader AAM industry.
AirPro News analysis
The FAA’s decision to grant a market survey authorization for an eVTOL aircraft marks a distinct shift in the regulatory treatment of Advanced Air Mobility platforms. Until now, eVTOL manufacturers have largely been restricted to experimental research and development flights, limiting prospective operators to simulators or ground-based evaluations. By allowing BETA to fly the A250 with actual stakeholders, the FAA is signaling increased confidence in the safety and maturity of the aircraft’s design.
We view this as a critical commercial catalyst. The ability to demonstrate real-world payload, noise profiles, and operational economics in flight will likely accelerate firm orders and infrastructure planning among early AAM adopters, setting a precedent that other eVTOL developers will undoubtedly seek to follow as they mature their own flight test programs.

Reliable Robotics Raises $115M, Valuation Tops $1 Billion
Reliable Robotics extends its Series D to $275M and crosses a $1B valuation as FAA certification work advances.

Reliable Robotics has secured $115 million in new capital, pushing the autonomous aviation startup’s valuation past the $1 billion mark and accelerating its push toward Federal Aviation Administration certification.
The Mountain View, California-based company announced the funding extension on October 20, 2026, in a press release. The capital injection upsizes its Series D round to $275 million and will fund the expansion of its aircraft fleet and production capacity for its Reliable Autonomy System.
Funding structure and strategic expansion
The new funding consists of $90 million in equity and a $25 million term loan provided by Silicon Valley Bank. This extension follows the initial $160 million Series D round announced on April 21, 2026. The latest injection brings the company’s total equity capital raised to date to more than $380 million.
A broad coalition of investors participated in the round, including Nimble Partners, Gideon Capital, RockCreek, Geek Ventures, Gold Hill Capital, Sparkwave Capital, Island Green Partners, and Allen & Company.
The company will use the funds to scale its operations and expand its physical footprint. Reliable Robotics is opening a new engineering hub in Bothell, Washington, which will serve as a center of excellence for its radar program by tapping into the established aerospace talent pool in the Seattle area. The company is also expanding with a new office in San Diego, California, supporting a workforce that now exceeds 250 employees.
Crossing $1 billion in valuation is a significant milestone in Reliable’s mission to deliver certified autonomous flight systems that make aviation safer and more accessible.
Certification timeline and technology
Reliable Robotics is actively submitting evidence to the FAA for the certification of its continuous autopilot engagement system. The technology is designed to manage engine startup, taxiing, takeoff, and landing while a pilot remains onboard the aircraft. The company expects to achieve FAA certification for this system within 18 to 24 months.
Robert Rose, co-founder and chief executive officer of Reliable Robotics, noted that the company continues to make steady progress and deliver evidence to the FAA, moving closer to certification with each submission.
The company is also developing its solid-state collision-avoidance technology, known as Reliable Radar. Certification for the radar system is expected by the end of 2027. These systems are engineered to prevent the leading causes of aviation accidents, specifically loss of control (LOC) and controlled flight into terrain (CFIT).
A secondary certification phase, which would remove the pilot from the cockpit entirely to enable fully remote operations, is projected to take at least three years.
Retrofitting the existing cargo fleet
Founded in 2017 by former SpaceX and Tesla engineers Robert Rose and Juerg Frefel, Reliable Robotics has adopted a distinct strategy within the autonomous flight sector. Rather than designing and manufacturing clean-sheet aircraft, the company focuses on certifying autonomous systems for integration into existing, proven airframes.
The initial target for commercial certification is the Cessna 208B Grand Caravan, a widely used turboprop in the regional Cargo aircraft market. By retrofitting certified aircraft, Reliable Robotics aims to integrate its technology into the existing National Airspace System without requiring new infrastructure or entirely new regulatory frameworks.
This approach has generated significant market interest. The company has secured over 200 commitments from commercial and military customers. In the defense and government sectors, Reliable Robotics holds a $17.4 million contract with the United States Air Forces and participates in National Aeronautics and Space Administration (NASA) Small Business Innovation Research (SBIR) Phase III agreements.
AirPro News analysis
We view the equity-plus-debt structure of this Series D extension as a calculated move by Reliable Robotics to secure necessary runway while minimizing ownership dilution. The autonomous aviation sector is highly capital-intensive, and reaching the certification finish line often requires more funding than initial projections suggest. By securing a $25 million term loan alongside the $90 million in equity, the founders are protecting their cap table while ensuring they have the resources to complete the rigorous FAA certification process.
Furthermore, the company’s strategy of retrofitting the Cessna 208B Grand Caravan provides a clearer path to revenue than competitors attempting to certify entirely new aircraft designs. By focusing on the autonomy system rather than the airframe, Reliable Robotics bypasses the aerodynamic and structural certification hurdles that clean-sheet manufacturers face. The military contracts and NASA agreements also provide non-dilutive capital and operational validation, which likely contributed to the company’s ability to achieve a valuation over $1 billion in a challenging venture capital environment.

Norway Selected for Electra EL2 eSTOL Demo Flights in 2027
Bristow, Electra, Avinor, and CAA Norway select five sites for hybrid-electric eSTOL demonstration flights in Q3 2027.

Bristow Group Inc., Electra, Avinor, and the Civil Aviation Authority of Norway (CAA Norway) have selected five locations across Norway to host demonstration flights of Electra’s hybrid-electric ultra-short takeoff and landing (eSTOL) technology demonstrator in the third quarter of 2027.
Announced in a joint press release on October 19, 2026, the initiative will test infrastructure, airspace integration, and regulatory frameworks across three distinct operating environments to prepare for the commercial introduction of hybrid-electric aircraft.
Testing eSTOL capabilities across diverse environments
The demonstration flights will take place at Horvnes quay near Sandnessjøen, Kongsbergporten Business Park, Trondheim Airport, Oslo Airport, and Mosjøen Airport. These locations were chosen to represent a cross-section of Norwegian aviation infrastructure, ranging from novel landing sites without established runways to short-runway regional facilities and major international aviation hubs.
The site selection follows an April 21, 2026 partnership agreement among the four organizations to use Norway as an international test arena for zero- and low-emission aviation technologies. Avinor, a state-owned company responsible for 43 airports and Norway’s air navigation services, is facilitating the infrastructure integration.
What matters is not the individual location itself, but that we are able to test the technology under different conditions and in different parts of the aviation system. This will give us insight into what is required in terms of infrastructure, airspace, procedures and regulations when new types of aircraft are ready to enter service in Norway.
The statement was provided by Karianne Helland Strand, Executive Vice President of Sustainability and Infrastructure at Avinor.
Bristow Group Inc., a global provider of aviation services, will operate the flights. Dave Stepanek, Executive Vice President and Chief Transformation Officer at Bristow, noted that the selected locations will allow the partners to demonstrate the operational flexibility of the aircraft across varied environments. He added that detailed planning for the 2027 flight demonstrations will now begin.
Regulatory integration and the path to commercial service
A primary objective of the 2027 flights is to generate data for regulatory authorities. FAA Norway will use the demonstrations to evaluate how eSTOL aircraft can safely share airspace with conventional air traffic and whether current aviation regulations require modification to accommodate hybrid-electric operations.
When we test new aircraft technologies in such a range of different scenarios, we will be able to assess whether the existing regulatory framework is fit for purpose. It is also valuable for us to build knowledge about how a new type of aircraft with specific characteristics can be safely integrated with other air traffic.
The remarks were made by Jan Petter Steinland, Director of Innovation, Research and Sustainability at CAA Norway.
Electra views the Norwegian demonstrations as a foundational step toward a new operational model. Diana Siegel, Vice President of Commercial Programs at Electra, stated that the flights will lay the groundwork for a “Direct Aviation ecosystem” that connects major airport hubs directly with communities lacking traditional runways.
Electra’s eSTOL development and market positioning
The aircraft slated for the Norwegian demonstrations is the Electra EL2, also known as the Goldfinch. The EL2 is a two-seat technology demonstrator that utilizes blown-lift aerodynamics and distributed electric propulsion to achieve takeoffs and landings in under 170 feet (approximately 50 meters). The demonstrator previously completed its first urban flight on June 2, 2026, landing on a pier in downtown Charleston, South Carolina.
Data gathered from the EL2 flights will inform the development of the Electra EL9, the company’s planned nine-passenger commercial variant. The EL9 combines electric propulsion with a turbogenerator powered by SAF. According to Electra, this hybrid approach aims to deliver 2.5 times the payload and 10 times the range of pure electric vertical takeoff and landing (eVTOL) aircraft, with 70 percent lower operating costs than traditional helicopters.
Electra has secured more than 2,200 letters of intent from over 60 commercial customers for the EL9. To meet this anticipated demand, the company announced an $850 million investment on July 21, 2026, to build a manufacturing facility in Springfield, Ohio. The factory is projected to produce up to 800 EL9 aircraft annually and create nearly 2,000 jobs.
On September 15, 2026, Electra signed an agreement with Atlas to manufacture and assemble airframes for the EL9 prototypes at facilities in Wichita, Kansas. The first prototypes are expected to be delivered for flight testing in 2027, aligning with the company’s target to achieve Federal Aviation Administration (FAA) Part 23 type certification in 2029.
AirPro News analysis
The selection of Norway as a testing ground highlights a strategic divergence in the advanced air mobility (AAM) sector. While much of the industry has focused on eVTOL designs for urban air mobility, Electra’s eSTOL approach bypasses the severe battery weight penalties associated with vertical lift. By requiring just 50 meters of runway, the EL9 can operate from repurposed maritime infrastructure, business parks, and the existing network of short-runway regional airports.
We view Norway as the ideal proving ground for this operational model. The country’s challenging geography of fjords and scattered coastal communities relies heavily on a subsidized regional air network managed by Avinor. If Bristow and Electra can successfully demonstrate reliable, low-emission operations in these environments during the 2027 test campaign, it will provide a compelling proof-of-concept for eSTOL technology as a viable replacement for aging regional turboprops and expensive helicopter transport.
