Eve Advances eVTOL Completes Hover and Low-Speed Flight Tests

Eve Air Mobility has reached another important milestone in the development of its electric vertical take-off and landing (eVTOL) aircraft after successfully completing the hover and low-speed phase of its flight test campaign. The achievement marks a significant step forward as the company prepares to enter the critical transition flight testing stage later this year.

Backed by aerospace giant Embraer, Eve announced that its full-scale engineering prototype has now completed 59 successful test flights, accumulating more than two hours and 27 minutes of flight time. The data collected during the campaign is expected to play a major role in refining the aircraft’s control systems, aerodynamic modelling and propulsion performance as certification efforts continue.

The latest phase forms part of Eve’s methodical “building-block” flight test strategy, where the aircraft’s flight envelope is expanded gradually while engineers validate simulations and control laws against real-world performance. This approach is widely regarded as essential in the development of next-generation urban air mobility aircraft, particularly as regulators demand increasingly rigorous safety validation before commercial operations can begin.

According to Eve CEO Johann Bordais, the completion of the hover and low-speed block demonstrates the effectiveness of the company’s disciplined testing philosophy. “Across 59 flights, we confirmed stable hover performance and predictable control behaviour within the envelope, while expanding our understanding of loads, aerodynamics, propulsion and energy management,” Bordais said.

During the campaign, the aircraft performed progressively more complex manoeuvres. Initial testing focused on operations below 15 knots, where engineers evaluated control laws, downwash characteristics, thermal management and propulsion behaviour. The programme later expanded to approximately 20 knots ground speed, including simultaneous four-axis manoeuvres designed to further validate aerodynamic and structural load models.

One of the more notable achievements during this phase was the successful demonstration of the aircraft’s autoland capability as well as a simplified fly-by-wire mode, which acts as a backup control layer should the primary system become unavailable. The prototype also reached an altitude of 215 feet above ground level and achieved a longest flight duration of 3 minutes and 48 seconds.

Engineers reported that noise levels remained within predicted limits while propulsion and battery performance exceeded expectations, both important factors for future urban air mobility operations where low noise and efficient energy use are considered vital for public acceptance and operational viability.

Marcelo Basile explained that the information gathered during the test phase provides critical validation for the company’s modelling systems. “Completing hover and low-speed testing gives us high-confidence data to validate and refine our aerodynamic, propulsion and load models,” Basile said. “That model correlation is what enables disciplined envelope expansion.”

The next stage of development will involve a series of ground tests ahead of transition flights expected to begin during the northern hemisphere summer of 2026. Transition testing represents one of the most challenging phases for eVTOL aircraft, as it involves the complex changeover from vertical lift flight to conventional wing-borne cruise flight.

Eve’s aircraft uses a “lift-plus-cruise” design, where dedicated vertical lift rotors handle take-off and landing while separate propellers provide forward thrust during cruise flight. Synchronising these systems safely and efficiently is regarded as one of the key technological hurdles facing the eVTOL industry.

The company continues to position itself as one of the leading players in the rapidly growing advanced air mobility sector, an industry that aims to introduce electric air taxi services in major cities worldwide over the coming decade. While widespread commercial eVTOL operations are still several years away, milestones such as Eve’s latest flight testing success indicate that the sector is steadily moving closer to reality.
