Vertical Aerospace (NYSE: EVTL) completed the maiden piloted flight of its final full-scale electric vertical takeoff and landing (eVTOL) prototype on June 5, 2026, doubling the manufacturer’s flight test capacity ahead of its upcoming Critical Design Review.

The flight took place at 8:49 BST at the company’s United Kingdom Flight Test Centre. According to a press release issued on June 9, 2026, the successful sortie followed the issuance of a new Permit to Fly from the UK Civil Aviation Authority (CAA) and marks the last major hardware iteration before the company establishes its certifiable design baseline.

Advancing toward Critical Design Review

The introduction of this final prototype is a prerequisite for the manufacturer’s Critical Design Review (CDR). Completing the CDR will freeze the aircraft’s design and clear the way for Vertical Aerospace to begin assembling its first pre-production airframes for the Valo four-passenger aircraft program.

Test Pilot Paul Stone commanded the June 5 flight. The addition of a second active aircraft to the test fleet allows the company to accelerate its data collection and validation processes.

“Getting our latest prototype into flight testing is an important milestone because it allows us to learn faster in real world conditions and keep building momentum towards certification,” Vertical Aerospace CEO Stuart Simpson said in the company announcement. “Expanding the flight test fleet will help us validate the aircraft more quickly, reduce risk, and move more efficiently towards bringing Valo into service.”

Dual-track flight test campaign

Vertical Aerospace is now operating two full-scale prototypes simultaneously. The company’s previous prototype is currently engaged in transition flight testing. That aircraft completed a milestone one-way transition flight on April 2, 2026, and continues to expand its flight envelope through thrustborne, wingborne, and transition phases.

The newly flown prototype will initially focus on all-electric flight testing. Once those phases are complete, the manufacturer intends to retrofit the aircraft for hybrid-electric flight testing. This future configuration is intended to support defense, logistics, and broader commercial applications beyond short-range urban air mobility.

The Valo program currently holds approximately 1,500 pre-orders from operators and lessors including American Airlines, Avolon, Bristow, GOL, and Japan Airlines.

Reaching the final prototype stage is a critical threshold for any eVTOL developer. For Vertical Aerospace, getting a second aircraft into the air mitigates the schedule risk inherent in relying on a single test article. If one aircraft requires maintenance or modifications, the flight test campaign can continue. We view the planned hybrid-electric retrofit as a strategic pivot to expand the Valo’s addressable market, acknowledging that pure battery-electric range limitations may restrict early commercial use cases. Securing the UK CAA Permit to Fly for this specific airframe also demonstrates ongoing regulatory alignment as the company approaches its CDR.

Japanese eVTOL manufacturer SkyDrive Inc. announced on June 24, 2026, that its SKYDRIVE Model SD-05 aircraft successfully reached a speed of 100 km/h during flight testing in Toyota, Japan, validating the aerodynamic stability and flight control systems of the 12-rotor multicopter.

In a press release issued by the company, SkyDrive stated the high-speed flight test campaign confirms the aircraft functions as predicted during the design and analysis phase. The 100 km/h milestone is considered the viable operating speed for the short-hop inter-urban commercial flights the company plans to launch in 2028.

Flight test parameters and technical validation

The achievement of the 100 km/h speed target verifies the performance of the aircraft’s propulsion, flight control, and avionic systems under high-speed forward flight conditions. The testing campaign in Toyota was designed to evaluate the aircraft’s high-speed stability, controllability, and maneuverability.

The SKYDRIVE Model SD-05 utilizes a compact multicopter architecture featuring 12 independent rotors. Reaching this speed demonstrates the maneuverability and controllability required to advance the aircraft toward type certification with Japanese regulators.

Certification progress and manufacturing

The flight test milestone follows recent regulatory progress for the manufacturer. On April 15, 2026, SkyDrive received Approved Design Organization (ADO) certification from the Japan Civil Aviation Bureau (JCAB).

The ADO certification allows the manufacturer to self-verify specific portions of airworthiness checks. This regulatory approval made SkyDrive the first dedicated eVTOL developer in Japan to secure ADO status. Production of the SD-05 aircraft is already underway, having commenced in March 2024 at a manufacturing facility owned by Suzuki Motor Corporation.

Commercial expansion and fleet orders

As the aircraft advances through flight testing, SkyDrive has accumulated commercial commitments both domestically and internationally. On May 12, 2026, the manufacturer announced a Letter of Intent with Tohoku Air Service for the purchase of one SD-05. This agreement marked the first aircraft sale commitment from a Japan-based helicopter operator.

Internationally, SkyDrive reached a general understanding on January 30, 2026, with Dubai-based AeroGulf Services Company LLC for the potential purchase of up to 20 SD-05 aircraft. The agreement represents the manufacturer’s first detailed commercial exploration outside of the Japanese market.

To support domestic operations, SkyDrive launched Japan’s first vertiport operators’ consortium on May 12, 2026. The initiative aims to promote commercial eVTOL services across the Kansai area, with a target of establishing 100 operational air taxis around Osaka by 2035.

We view the 100 km/h flight test milestone as a critical technical gate for the SD-05 program. Multicopter designs that rely on 12 independent rotors without a transitional wing face distinct aerodynamic challenges at higher forward speeds. Validating stability at 100 km/h indicates the flight control software and rotor pitch mechanisms are successfully managing the differential thrust required for forward flight. Combined with the recent JCAB ADO certification and the manufacturing partnership with Suzuki Motor Corporation, SkyDrive is assembling the necessary regulatory and industrial framework to meet its 2028 commercialization target.

Researchers at the Georgia Institute of Technology have developed a system that allows autonomous aircraft to transcribe and interpret pilot-to-pilot radio transmissions, reducing trajectory prediction errors by more than half. The framework aims to integrate Drones safely into airspace around non-towered airports without requiring human pilots to alter their standard communication procedures.

According to a press release issued by the university on June 23, 2026, nine out of 10 airfields globally operate without active air traffic control towers. At these facilities, pilots rely on shared radio frequencies to announce their positions and intentions. The Georgia Tech team, led by robotics Ph.D. student Sundhar Vinodh Sangeetha and Assistant Professor Sarah Li, presented their findings at the IEEE International Conference on Robotics and Automation in June 2026. Their research addresses a critical gap in uncrewed aerial systems integration by translating natural language radio calls into actionable navigational data.

Translating radio calls into trajectory data

The multimodal framework utilizes speech-to-text software combined with a modified large language model to process standard aviation radio transmissions. By inferring pilot intent from these calls, the system feeds the resulting data into existing trajectory prediction algorithms used by autonomous aircraft.

The researchers validated the system using flight data and recorded radio calls from a non-towered airport in Pennsylvania. The integration of voice data reduced the average error in predicting an aircraft’s flight path from nearly one kilometer to approximately 400 meters, representing a reduction of greater than 50 percent.

Sangeetha stated in the release that human pilots should not have to change their behavior to accommodate autonomous operations. “This is how humans have operated safely for decades around these airports,” Sangeetha said. “So, if we start flying robots here, they should operate in the same way.”

Regulatory context and future applications

The development aligns with ongoing regulatory efforts by the Federal Aviation Administration (FAA) to manage mixed-use airspace. On February 4, 2026, the U.S. Government Accountability Office published a report (GAO-26-107648) highlighting the necessity for the FAA to establish protocols for how drones will communicate with and avoid crewed aircraft within the National Airspace System.

The Georgia Tech team envisions the technology not only as a collision avoidance tool for drones but potentially as an automated safety monitor for non-towered Airports, capable of warning human pilots of impending conflicts before accidents occur.

The researchers are also exploring bidirectional communication capabilities for autonomous systems.

“We’ve shown we can turn language into position. Can we go backwards and generate that language so the autonomous aircraft can announce its intention and coordinate with humans on the same channels?” Li said in the university statement.

We view the integration of natural language processing into uncrewed aerial systems as a necessary bridge for near-term airspace integration. While the FAA and industry stakeholders have heavily invested in digital datalinks and automatic dependent surveillance-broadcast (ADS-B) technologies, the reality of general aviation is that voice communication remains the primary method of deconfliction at non-towered airports. A system that allows autonomous aircraft to passively monitor and interpret standard common traffic advisory frequency calls mitigates the immediate need for costly avionics upgrades across the legacy general aviation fleet. The challenge moving forward will be certifying large language models for safety-critical aviation applications, a hurdle regulators are only just beginning to evaluate.
