The company on Wednesday announced it completed the first stage of power system integration testing, during which the technology was put through a series of simulated flights in a controlled environment.

As the firm works to manufacture its first two Lilium Jets, which it began assembling in December, these tests will help it demonstrate the aircraft’s powertrain performance and safety to the European Union Aviation Safety Agency (EASA). It seeks to certify the design under the regulator’s Special Condition for VTOL (SC-VTOL) rules by 2026 before rolling it out to customers worldwide.

The Lilium Jet’s powertrain comprises 30 battery-electric engines within flaps on the main wing and canard, which stow during cruise flight. Honeywell and Japan’s Denso are the main suppliers for the engine components.

The unique configuration is designed to give the aircraft the speed of a jet—about 154 mph (134 knots)—with the vertical takeoff and hover capabilities of a helicopter. Fully charged, Lilium expects it to be able to carry six passengers plus a pilot on city-to-city trips as long as 109 sm (95 nm).

The company’s electrical power system lab, located at its headquarters and test campus, was developed with help from aerospace testing specialist EN4 using software and hardware from test equipment provider NI.

According to the manufacturer, it has the ability to replicate the entire Lilium Jet powertrain from battery pack to engine. The lab’s low voltage systems can power the aircraft’s avionics and cabin systems. In addition, it boasts a functioning charging station and structures to mitigate the release of energy.

In the words of Gianluca Franchi, business development director of EN4, the facility is a “cutting-edge test rig, which has been designed to be a long-term asset supporting the Lilium Jet through certification and beyond.”

Lilium engineers are using a specially tailored software to chart flight profiles and run tests on the system. The company is collecting real-time data on those simulations, which will be shared with airworthiness authorities as evidence of compliance with its type certification requirements, it said.

“In this new lab, we test flights, charging, and simulate failure scenarios to ensure that our powertrain meets stringent aviation safety and reliability standards,” said Stephen Vellacott, chief technology officer of Lilium. “From first flight to certification and product launch, the lab enables us to demonstrate that our aircraft will be a world-leading product.”

Once power system testing is complete, the next major step for Lilium will be to fly the entire aircraft. The first jet off its production line will be deployed solely for ground testing, but the second is expected to make the model’s debut flight in early 2025.

The company so far has flown two Phoenix test aircraft, a full-scale, five-seat design intended to mirror the aerodynamics and hardware of its flagship model, and reached a cruise speed of 136 knots.

In June, it fired up the Lilium Jet’s engine to full throttle, marking another step toward crewed flight.

The manufacturer has begun ground testing a new, more advanced full-scale prototype of its flagship VX4 air taxi after an initial prototype was damaged during an uncrewed flight test last year.

A failed pylon affected the way the aircraft’s flight control system communicated with its motors, causing it to tumble from about 30 feet in the air onto the runway at Cotswold Airport (EGBP) in the U.K.

Vertical’s latest prototype air taxi is more powerful, capable of reaching 150 mph—the intended cruise speed for its flagship model—courtesy of an improved power-to-weight ratio. It features new propellers, which were developed prior to last year’s crash, and proprietary battery technology manufactured at a dedicated facility in Bristol.

Sixty percent of the aircraft’s technology and components come from suppliers including Honeywell, Leonardo, GKN Aerospace, Hanwha, and Molicel, compared to 10 percent on the first prototype. The company is also developing an identical prototype.

The new aircraft and its systems have been tested and commissioned, and Vertical has already completed initial ground testing, including propeller balancing and spinning tests that measure the weight distribution of each blade. The next step will be powered propulsion system testing of the air taxi’s powertrain and battery packs, during which the engines will be run while the vehicle is anchored. 

After that, Vertical will need to secure a permit to fly from the U.K.’s Civil Aviation Authority (CAA), which will allow it to move to the “wheels up” phase: crewed testing of tethered aircraft and low-speed untethered flights. It will also need to perform thrustborne, wingborne, and transition flights, demonstrating that the aircraft can maneuver and gain lift as expected.

The manufacturer’s type certification safety target is the same as that for commercial airliners. Its flagship model will enable a pilot to fly as many as four passengers up to 100 sm (87 nm) while producing zero operating emissions and just 50 dBA of noise during cruise, which the company says allows it to fit seamlessly within an urban soundscape. The firm claims it will be capable of flying from Miami to Fort Lauderdale, Florida, in only 11 minutes.

Despite suffering a crash, Vertical continues to receive support from the U.K. government, which in February awarded it $10 million to develop its next-generation propellers. The allocation brings the manufacturer’s total U.K. government grant funding received to $47 million

Vertical founder Stephen Fitzpatrick also committed $50 million to the company, which he predicted would keep it liquid through mid-2025. The money will be used to support the aircraft testing and certification process, which the manufacturer hopes to complete by the end of 2026.

The German manufacturer on Tuesday said it completed initial testing of its flagship aircraft’s propulsion unit, comprising a pair of electric engines and mounting system. For the first time, the engines were taken up to full throttle on a test bench at the company’s headquarters in Munich.

According to Lilium, the propulsion unit performed as expected, representing a key step toward the aircraft’s first crewed flight planned for later this year. The firm will need to demonstrate crewed operations for the European Union Aviation Safety Agency (EASA) in order to receive type certification in 2025 ahead of a planned 2026 commercial launch.

“For my fellow co-founders and myself, the first test run of the Lilium Jet propulsion unit marks another high point in our journey,” said Lilium co-founder Daniel Wiegand. “It was our shared belief in the radical potential of electric jet technology that brought us together in 2015 and continues to drive Lilium.”

The propulsion unit engines were developed by Lilium in collaboration with a handful of suppliers. Honeywell and Japanese firm Denso supplied the electric motor, Dutch manufacturer Aeronamic provided the compressor fan, and Sweden’s SKF delivered electric motor bearings.

The mounting system, which forms the rear part of the aircraft’s wings and front aerofoils, contains the propulsion unit and a vectoring system.

The system is designed to power the Lilium Jet’s 10 independent battery packs, which feed 36 electric ducted fans. The fans are embedded in the aircraft’s fixed wings and allow it to take off vertically like a helicopter.

The jet will primarily serve routes between towns and inner cities, cruising at 162 knots on trips spanning 25 to 125 sm (22 to 109 nm).

Lilium began production of its flagship aircraft in December with the delivery of the first of seven fuselages to its assembly line in Wessling, Germany. Since then, it has begun manufacturing battery packs and installing an electric propulsion unit serial production line at the facility. Those systems initially will be deployed on the ground and eventually be integrated on the aircraft used for flight testing.

On Tuesday, Lilium said supplier Aernnova has completed the build of the propulsion mounting system. In addition, partner Sener this month delivered the first set of servo-actuators, which rotate the propulsion unit as the aircraft transitions between vertical and horizontal flight.

“Over the past years, we have invested heavily in the technology and secured extensive IP rights,” said Stephen Vellacott, chief technology officer of Lilium. “We now move a step closer to first manned flight and beyond that to the era of commercial electric flight.”

After obtaining EASA type certification in 2025, Lilium intends to secure the same approval from the FAA by leveraging a Bilateral Aviation Safety Agreement between the regulators. It is the only eVTOL manufacturer with certification bases from both the FAA and EASA.

In the U.S., Lilium intends for the jet to initially serve customers in South Florida and Southern California through a partnership with newly formed eVTOL operator UrbanLink, which in May placed an order for 20 aircraft. Earlier this week, UrbanLink partnered with Ferrovial Vertiports to build electric aircraft infrastructure in those markets.

The Army on Thursday awarded a $1.9 million Small Business Innovation Research (SBIR) contract to Electra.aero, the manufacturer of a nine-passenger, hybrid-electric short takeoff and landing (eSTOL) design, to perform powered wind tunnel testing.

Similar to Electra’s other SBIR and Small Business Technology Transfer (SBTT) Phase II and III engagements with AFWERX, the innovation arm of the U.S. Air Force, the Army contract is a quid-pro-quo arrangement.

Electra will get the opportunity to leverage military test facilities as it collects data that will inform aircraft design and development. The Army, meanwhile, can explore the eSTOL’s unique capabilities—such as its miniscule runway requirement—for logistics operations in “contested” environments.

“There is a substantial benefit to employing the right-sized aircraft for a given payload-range mission,” said Ben Marchionna, director of technology and innovation at Electra. “Many of the most commonly deployed military logistics solutions in use today are flown well below their intended payload capacity. Our eSTOL aircraft can fulfill these missions while using dramatically less fuel, providing much more range, operating at significantly reduced noise levels, and utilizing the same constrained operational ground footprints.”

According to Electra, the eSTOL cruises at 175 knots and is capable of carrying up to nine passengers or 2,500 pounds of cargo. The company claims it will have more than twice the payload, 10 times the range, and 70 percent lower operating costs compared to electric vertical takeoff and landing (eVTOL) alternatives, while offering lower noise and fuel consumption.

The aircraft has a range of 500 nm for commercial use cases. But with range extensions, the Army will be able to fly it for 1,000 nm.

The defining feature of Electra’s design is its use of blown-lift technology, which redirects slipstream flows over the aircraft’s wings into large flaps and ailerons. By “multiplying lift,” as Electra puts it, the eSTOL can take off at just 35 mph, reducing the runway requirement to 150 feet.

Electra says it is the first manufacturer to deploy blown lift in an aircraft with a distributed electric propulsion system. That system takes the form of eight electric motors powered by a turbogenerator. The latter can run on both electricity or traditional aviation fuel and recharges the aircraft’s batteries in flight. Because of this, airports will not need to install electric aircraft chargers to accommodate it, Electra says.

The manufacturer intends to certify its flagship model as a fixed wing aircraft under FAR Part 23 and EASA CS-23, allowing it to be operated with a standard fixed wing pilot’s certificate. That removes a key hurdle facing the eVTOL industry, which will need to train a new generation of powered-lift-certified pilots under FAA proposals.

The Army will be one of the earliest users of the eSTOL, but Electra has plenty of commercial arrangements lined up. Those include more than 2,000 preorder sales of its flagship aircraft to major customers, among them American operators Bristow Group and JSX and India’s JetSetGo

This week, the manufacturer announced a partnership with Wilbur Air, the newly formed operator subsidiary of Australian vertiport developer Skyportz. Electra and Skyportz in 2021 signed a letter of intent for 100 aircraft.

Electra expects to begin eSTOL deliveries in 2028 following certification.

The company on Friday said it successfully completed a series of drop tests on Midnight’s battery packs, an evaluation it will need to complete again during for-credit testing with the FAA. A key step toward type certification for eVTOL designs, for-credit testing allows the regulator to gauge how well an aircraft conforms to its approved specifications.

Archer said it wrapped up the first phase of uncrewed Midnight flight testing in January and intends to begin piloted evaluations later this year. Following the completion of those tests, it will prepare for the FAA’s final exam.

The manufacturer considers the battery pack drop test significant, claiming it is regarded by the electric aviation industry as “one of the most difficult tests to pass for an eVTOL aircraft.”

Midnight’s six lithium-ion battery packs power a dozen electric engines. The aircraft’s tiltrotor configuration positions six propellers on each side of its fixed wings: During cruise, the front propellers tilt forward to provide thrust, while the back propellers lock in place.

The air taxi can carry a pilot and up to four passengers (or 1,000 pounds of cargo) as far as 100 sm (87 nm) at a cruise speed of 130 knots. It is optimized for back-to-back, 20-to-50 sm (17-to-43 nm) trips, with minimal charge time in between.

The drop test is designed to ensure Midnight’s battery packs could withstand a significant impact, similar to the 50-foot fuel tank drop test for rotorcraft and fixed-wing aircraft. Like fuel tanks, battery packs are flammable and could leak, catch fire, or even explode in the event of a crash.

The first 50-foot drop test for eVTOL aircraft batteries took place in 2022 at a National Institute for Aviation Research (NIAR) lab at Wichita State University in Kansas. It was sponsored by the FAA and conducted by NIAR and Beta Technologies, which is producing an eVTOL air taxi as well as a conventional takeoff and landing (eCTOL) variant. Recently, the European Union Aviation Safety Agency (EASA) adopted the test as a formal part of its own certification for battery-powered aircraft.

To simulate “extreme impact scenarios,” Archer dropped packs from a height of 50 feet at 100 percent, 30 percent, and 0 percent charge at a NIAR lab. The company said the batteries showed no signs of failure, and they actually functioned properly after each drop.

The company attributed the test’s success to its choice of using cylindrical cells produced by Molicel in its proprietary design. U.K.-based eVTOL manufacturer Vertical Aerospace is also using cylindrical cells from Molicel on its VX4 model.

Archer believes it will be able to replicate the results of the drop test for the FAA when the time comes. In February, the company began production of three type-conforming Midnight models to be used in those for-credit evaluations.

“Successfully passing the battery pack drop tests marks a pivotal moment that paves the way for future ‘for-credit’ certification testing with the FAA,” said Alex Clarabut, battery lead for Archer. “This accomplishment highlights our dedication to not just meeting but exceeding safety standards. It is a critical step towards our goal of ensuring that Midnight will be among the safest aircraft in the skies.”

Archer also has a battery testing collaboration with NASA. The space agency will gauge the batteries’ safety, energy, and power performance using the European Synchrotron Radiation Facility (ESRF), one of the world’s most advanced high speed X-ray facilities. The partners aim to understand how battery cells function in “extreme abuse cases” in order to safely integrate them into advanced air mobility (AAM) services and, potentially, spaceflight.

Archer said the partnership’s focus on batteries will expand to other technologies under a Space Act Agreement calling for the development of “mission critical” eVTOL systems.

The firm on Thursday announced it successfully completed a hybrid-electric ground test using sustainable aviation fuel (SAF) from partner Dimensional Energy. The pure, 100 percent ASTM D7566 SAF is produced from electricity and carbon dioxide and was used to fuel Ampaire’s nine-seat Eco Caravan, a modified Cessna 208B Grand Caravan.

The goal of testing was to validate the performance of Dimensional Energy’s pure e-fuel SAF. According to Ampaire, the results “exceeded expectations,” demonstrating a massive increase in energy efficiency compared to traditional jet fuels.

Both Ampaire and Dimensional Energy received funding and support from climate technology investor Elemental Excelerator. According to Ampaire, the investment has helped the partners more than double the efficiency of SAF consumption while driving emissions to near zero.

“By showcasing the transformative efficiency gains achievable through hybrid-electric propulsion, we are driving the future of eco-friendly air travel,” said Kevin Noertker, CEO of Ampaire. “For those already recognizing the potential of SAF, its integration into our hybrid-electric aircraft enhances its appeal even further.”

Ampaire’s Eco Caravan is a hybrid-electric design with a range of 1,100 sm (956 nm) and a payload of 2,500 pounds. In 2022, the manufacturer said the model could be the first electric regional aircraft to fly commercially. Ampaire expects FAA certification this year.

The aircraft is equipped with Ampaire’s proprietary AMP-H570 AMP Drive hybrid-electric propulsion unit. According to the company, the system will reduce fuel consumption and emissions by 50 to 70 percent compared to conventional Pratt & Whitney PT6 engines, which are common on Cessna Caravan turboprops.

Ground tests paired the hybrid-electric propulsion system with Dimensional Energy e-fuels to “reimagine” 100 percent electric flight and address SAF quality and cost concerns, the goal being to enable broader use. According to Ampaire, Dimensional Energy has two projects that will “add significant inventory to the world’s availability of e-fuels.”

“Technology providers have to collaborate beyond innovation and into execution,” said Jason Salfi, CEO of Dimensional Energy. “By combining Dimensional Energy e-fuels with Ampaire’s aircraft technology that can reduce the amount of fuels combusted during flight, we quicken the pace up the steep curve of the energy transition and reduce the need for extraction faster.”

Nonprofit investor Elemental Excelerator provided both Ampaire and Dimensional Energy with project development capital and years of support to scale the companies’ tech. The three partners intend to continue their collaboration and research into sustainable flight.

“[Ampaire and Dimensional Energy’s] innovations reduce pollution and noise in neighborhoods around airports and make possible a cleaner way to fly,” said Dawn Lippert, CEO of Elemental Excelerator.

Ampaire’s recent ground test wasn’t the company’s only milestone in the past few months. In fact, it doesn’t even come close to the firm’s biggest achievement: a 12-hour, 1,375 sm (1,195 nm) flight of its Electric EEL demonstrator. The flight set a high-water mark for hybrid-electric aircraft endurance, eclipsing the company’s previous record.

The EEL is a modified Cessna 337 Skymaster, also equipped with the AMP-H570 AMP Drive, that functions primarily as a testbed aircraft but could also serve owner-flown, charter, and short-haul regional airlines and carriers. It has a 400 sm (348 nm) range and 450-pound payload.

In 2020, Ampaire and the EEL also completed the first trial of a hybrid-electric aircraft along an actual airline route, in partnership with Hawaii’s Mokulele Airlines. The Eco Caravan, meanwhile, made its maiden voyage in 2022.

Ampaire’s largest order for the hybrid-electric design comes from U.K.-based lessor Monte Aircraft, which agreed to order up to 50 Eco Caravans. The firm also has an agreement with Azul Conecta—a subsidiary of Azul, Brazil’s largest airline by passenger volume—to convert six Grand Caravans in its fleet.

Meanwhile, Ampaire is working with NASA on several projects, most notably one that would install its propulsion system aboard a Twin Otter DHC6. It has an agreement with private charter operator WingTips for the conversion of 50 Twin Otters to Eco Otters—another Ampaire concept—in addition to 20 Caravans.

Unsurprisingly, major airlines and manufacturers are ramping up development of SAF as Ampaire matures its tech. Both Gulfstream Aerospace and Virgin Atlantic completed inaugural transatlantic flights fueled entirely by SAF in November. Rolls-Royce that month said all of its current engines can now run on 100 percent SAF.

According to the International Air Transport Association (IATA), SAF production tripled from 2021 to 2022. And with aviation industry groups working to speed its adoption, the dawn of SAF appears to be on the horizon.

Reliable Robotics, which completed the landmark flight using its remotely operated aircraft system (ROAS), claims to be the first in the industry to agree on a testing and analysis campaign for these systems with the FAA. The company will demonstrate how its ROAS aligns with the regulator’s safety and performance requirements for operations in the contiguous U.S. and Alaska.

“We are immensely pleased with the FAA and the positive working relationship we’ve established together—it is clear that we share the common goal of improving aircraft safety through automation,” said Chris Schulenberg, certification program manager at Reliable.

Reliable’s ROAS is intended to reduce or eliminate accidents due to pilot error or impairment, such as controlled flight into terrain (CFIT) and loss of control in flight (LOC-I), which it says account for the bulk of fatal aviation accidents. Initially, the firm will supplement personnel in the cockpit rather than replace them. It intends for operations to include a single onboard pilot to perform “abnormal procedures.”

The means of compliance for assessing the ROAS’ navigation and autopilot systems have been accepted through the FAA’s issue paper process. The blueprint sets out criteria for approving the technology and comprises a portion of the company’s supplemental type certification (STC) process.

That campaign kicked off in 2022, when the FAA approved Reliable’s G-1 issue paper. The G-1 defines the certification basis for its STC on the Cessna Caravan, including navigation and autopilot systems. The company’s certification plan for continuous autopilot engagement—a road map that uses existing FAA regulations and processes for normal and transport category aircraft, with no special conditions or exemptions—was accepted in June.

The regulator has also conducted several test flights with Reliable through its Urban Air Mobility (UAM) Airspace Management Demonstration program, culminating in its signoff on December’s historic flight. The Caravan used in that demonstration—a loan from potential customer FedEx—is one of many Reliable intends to retrofit with its automated tech. 

The company is working with both Textron Aviation and Textron eAviation—the sustainable flight subsidiary of Textron—to install its ROAS onto the popular model. Textron has delivered more than 3,000 Caravans, making it one of the most widely used turboprops in the world. Reliable’s remotely piloted Caravan could introduce same- or next-day shipments of time-sensitive deliveries to locations currently served by piloted models.

However, the firm’s tech is also designed to be aircraft agnostic. It could one day be equipped on other Textron designs or those of different manufacturers. The company says this could even include cargo aircraft designed for 3,000-plus-pound payloads—small cargo aircraft are a possible candidate for early autonomous operations, with low risk due to the lack of passengers.

In addition to the FAA, Reliable has completed watershed technology demonstrations with NASA and AFWERX, the innovation arm of the U.S. Air Force. In January, it was awarded military airworthiness approval to begin further flight testing and perform operational missions for the Air Force using remotely piloted aircraft.

The project launched this week with the introduction of GAMI’s G100UL during initial flights in Ada, Oklahoma. Beginning with a baseline of two freshly overhauled Continental IO-520 engines, the Baron will be operated under AOPA management, with the cooperation of Savvy Maintenance founder and technician guru Mike Busch, using the company’s computerized diagnostic tools to analyze engine data and compare it against the information it has collected from “hundreds of thousands of hours of GA flights,” according to an AOPA release.

An AOPA spokesperson told FLYING that the association is staging in Ada right now “since that is where the majority of the fuel is, and it makes sense to use [it] as a geographically appealing hub.” Presumably this will allow AOPA the “best efficiency in demonstrating the fuel to a wide range of people.” GAMI’s fuel obtained a supplemental type certificate, covering a broad range of piston aircraft, from the FAA in September 2022. The initial STC for Lycoming O-320, O-360, and IO-360 engines came in July 2021.

AOPA president Mark Baker was at the controls for the demonstration flight to kick off the program on October 31. For one hour, Baker flew with G100UL feeding the left engine and standard 100LL powering the right one.

“We wanted to get some actual experience with a 100-octane unleaded fuel in the kinds of airplanes and engines that our members own and fly,” said Baker. “This fuel has been tested extensively in labs and received an FAA STC. Should the FAA approve additional fuels, we’ll test them, too, so we can see what they’re like to use out on the airways.

This week, the regulator and the military’s aviation arm agreed to exchange flight test data and combine their capabilities for testing AAM aircraft designs, such as electric vertical takeoff and landing (eVTOL) or autonomous aircraft. The new collaboration is meant to mature—and safely integrate—the emerging technologies with airports, individual pilots, policies, communications, and other aircraft within the nation’s complex national airspace system (NAS).

“A new era of aviation is taking off, and safe and efficient operations require collaboration,” said John Maffei, the FAA’s technology development director. “This data will help inform FAA certification efforts, policies, standards, and future airspace integration requirements.”

On Wednesday, Maffei on behalf of the FAA signed a memorandum of understanding (MOU) with Colonel Elliott Leigh, chief commercial officer for the Air Force and the director of AFWERX, a technology directorate within the Air Force Research Laboratory that serves as the department’s innovation arm. AFWERX’s goal is to accelerate new aircraft capabilities by connecting private sector companies with department resources, including airmen.

“We intend to utilize all the various aircraft and traffic management systems we have access to in order to help the FAA gain the data they need to accelerate regulatory changes to enable emerging technology integration,” Darshan “Dash” Divakaran, AFWERX head of airspace innovation and Prime partnerships, told FLYING.

The signing of the MOU took place during an event at Duke Field (KEGI), a military airport at Florida’s Eglin Air Force Base. The airfield houses the 919th Special Operations Wing, an Air Force Reserve unit.

Two manufacturers working with AFWERX, Joby Aviation, and Beta Technologies have already delivered an eVTOL aircraft and an electric aircraft charger, respectively, to Eglin. Beta this week also flew its Alia eCTOL (electric conventional takeoff and landing) on a 1,500 nm journey across 12 states, landing at Duke Field on Thursday. The companies will train Air Force pilots to fly their respective aircraft, which will soon be used to conduct testing and experimentation.

“Even prior to the signing of the MOU, AFWERX Prime and the FAA began exploring ways to integrate efforts and share data,” said Divakaran. “One example is the Prime Logistics team meeting with the Emerging Technology office within the FAA’s Office of Airports to share information and lessons learned through the installation of the first eVTOL charging station on a DOD installation at Duke Field.”

AFWERX and the FAA emphasized that the MOU supports the development of U.S.-built aircraft in particular, as well as the infrastructure and regulations that will enable safe integration.

“We are driving progress in propulsion technology, in manufacturing and materials, and in test and safety for a novel class of air vehicles,” said Leigh. “Keeping this effort rooted in the United States, building our national security and accelerating innovation for our airmen and guardians are all crucial for the Air Force… I am excited about this industry’s direction and the Air Force’s role in shaping it.”

Just in the past three years, AFWERX has awarded more than $345 million in contracts to 36 electric aircraft and technology developers, which supports the country’s developing national AAM strategy, said Leigh. By his estimate, Air Force investments, certifications, partnerships, and testing have helped the program funnel over $11 billion in commercial investment into the AAM sector.

Specifically, the MOU was signed between the FAA and AFWERX Prime, a subdivision seeking to “prime” emerging commercial markets. Prime offers a sort of quid pro quo: The Air Force provides resources for contracted private companies to field their aircraft more quickly, while the military gets to explore use cases for designs not yet on the commercial market.

Joby, for example, had its eVTOL air taxi in the skies above Eglin within a week of delivery—and well ahead of its expected commercial launch in 2025. The Air Force, meanwhile, received a shiny, new aircraft to test unexplored military applications. Everybody wins.

Joby and Beta are far from the only eVTOL manufacturers under contract with AFWERX. Competitor Archer Aviation, for instance, signed a deal worth up to $142 million for the delivery of six Midnight air taxis in July. Another firm, Jump Aero, recently extended its contract, while Pipistrel this week sealed the first AFWERX agreement for its Velis Electro.

Now, the FAA will have access to the data and learnings these firms uncover while flying with the Air Force.

“This MOU is a big step for the future of AAM and provides industry and investors the confidence needed to accelerate forward,” said Divakaran in a press release. “This partnership validates why the DOD created the AFWERX Agility Prime program to focus on AAM and dual-use technology.”

This week’s agreement comes a few months after the FAA released Innovate28, its plan to enable safe, near-term AAM operations using existing infrastructure, regulations, and systems. The agency hopes it will culminate in scaled operations in time for the 2028 Olympic Games in Los Angeles, where several eVTOL air taxi firms are expected to ferry spectators and athletes around the city.

FAA officials believe the MOU supports Innovate28’s initial entry into service targets. Future phases, as described by the agency’s Urban Air Mobility Concept of Operations (UAM ConOps), released in May, could also be impacted. The UAM ConOps is essentially a blueprint that provides guidance on AAM operations down the line as the industry matures.

“We intend to continue to explore areas for integrated testing by collaborating with the FAA’s Innovate28 team, which is consolidating research and data requirements from across the FAA’s lines of business,” Divakaran told FLYING.

Collaborating with the Air Force could help the FAA make up some ground on U.S. leadership in the eVTOL space. 

To the surprise of many in the industry, the agency last year reversed course on eVTOL classification. Rather than obtaining type certification in the normal class under Part 23 light aircraft regulations—which was the expectation for years—manufacturers were informed they would need to switch to the special class process under FAR 21.17(b), certifying in the newly added “powered lift” category. The change forced the FAA to reissue certification bases to a handful of firms, including Joby and Archer.

Since then, the FAA published a final rule that defined powered-lift operations in regulations covering other commercial operations, such as airlines or charters. It also proposed a rule for training and certifying powered-lift pilots, though the proposal was widely panned by several major industry groups.

On Wednesday, Joby revealed that four test pilots have now completed flights aboard its air taxi, marking the firm’s transition to crewed flight testing. The addition of onboard pilots is a major boon to Joby’s efforts to type certify the aircraft with the FAA. The initial crewed tests, which took place at the company’s pilot production facility in Marina, California, covered free thrustborne hovers and forward transitions to semi-thrustborne flight.

Joby’s tiltrotor eVTOL is designed to carry a pilot and four passengers over a distance up to 100 sm (87 nm), cruising at 200 mph (174 knots). The company says the aircraft’s quiet noise profile will make it barely audible within a city’s soundscape.

The recent flights build on the surprise delivery of the first Joby eVTOL to Edwards Air Force Base in California, originally scheduled for early 2024. There, Joby and Air Force pilots will evaluate the aircraft’s capabilities in settings similar to those it will face when it begins flying air taxi routes with Delta Air Lines. That service is expected to launch in 2025, beginning in New York and Los Angeles.

James “Buddy” Denham, Joby’s chief test pilot, led the pilot-on-board campaign, which was designed to gather data on the air taxi’s handling abilities and pilot control interface. Denham left the Naval Air Systems Command—where he pioneered a concept for aircraft carrier precision landings and led research and development of the Unified Control Concept, which was integrated into F-35B STOVL aircraft—to join Joby in 2019. 

Joby credited Denham as a major influence in the development of its own flight controls. The chief test pilot had some nice things to say about the company as well.

“Having helped design and test flight controls for a wide variety of aircraft, including all three variants of the F-35 Joint Strike Fighter, nothing compares to the simplicity and grace of the Joby aircraft,” said Denham. “After completing more than 400 vertical takeoffs and landings from the ground, it is a privilege to sit in the cockpit of our aircraft and experience firsthand the ease and intuitive nature of the design that the Joby team has developed.”

During testing, pilots assessed the ease of conducting maneuvers that will become routine when commercial operations begin. These included vertical takeoffs, acceleration and transition to forward flight, runway centerline tracking, and deceleration into vertical landings. 

Joby said appraisals of the flights will aid its progress toward type certification, as well as its activities with the Air Force’s Agility Prime program. Agility Prime is the vertical lift division of AFWERX, the Air Force’s innovation arm. Earlier this year, Joby and Agility Prime extended their research and development contract, bringing its total value to $131 million.

Type Certification: On the Horizon?

Previously, Joby tested its eVTOL with pilots on the ground, using a ground control station equipped with state-of-the-art communications systems to guide it remotely. Those flights gave the company data on the aircraft’s performance in a wide array of operational conditions. But the beginning of crewed testing figures to be more consequential.

After pilot-on-board testing of the preproduction prototype is complete, the stage will be set for Joby to begin “for credit” flight testing with the FAA, using a full-scale production prototype. That model may be built at the company’s scaled manufacturing plant in Dayton, Ohio, which was first announced last month.

Dayton’s claim to fame is that the Wright brothers lived, worked, and opened the nation’s first airplane factory there (hence the Flyers mascot). It’s also home to Dayton International Airport (KDAY), where Joby will build its manufacturing plant on a 140-acre-site. The space is large enough for the company to one day install up to 2 million square feet of facilities. It is expected to produce 500 aircraft per year and create as many as 2,000 jobs.

Construction will begin next year, with full-scale operations scheduled for 2025. In the meantime, Joby will use nearby existing buildings to begin initial manufacturing activities. The goal will be to wheel the first service-ready aircraft off the production line within two years, in time for the company’s commercial launch with Delta.

In addition, Joby has commercial operational deals in place with Japan’s ANA Holdings and South Korea’s TMAP and SK Telecom to launch services in those countries. It also has an agreement with Uber—part of the 2020 acquisition of Uber Elevate—to integrate its ridesharing service into the company’s app.

However, all of this hinges on Joby’s ability to prove to the FAA that its air taxi is airworthy. Luckily, rivals such as Archer Aviation and Lilium are going through the same (lengthy) process. Archer, for its part, also received the FAA greenlight to begin flight testing its preproduction prototype in August. Lilium, meanwhile, is the only eVTOL manufacturer to obtain certification bases from both the FAA and the European Union Aviation Safety Agency (EASA).

The three firms—plus Boeing-owned Wisk Aero and Germany’s Volocopter—are all competing to be top dog in the advanced air mobility (AAM) industry, which is expected to take off soon with the FAA’s announcement of the Innovate28 plan for early eVTOL operations. Whichever firm achieves type certification first will realize a lot of lift.
