By Brazil Stock Guide – Eve Air Mobility (NYSE: EVEX; B3: EVEB31) said it completed a key phase of flight testing for its engineering prototype, marking another step in the development of its electric vertical takeoff and landing aircraft.
The company, backed by Embraer SA (B3: EMBR3; NYSE: ERJ), said on Thursday (21) that the prototype carried out 59 successful flights, accumulating 2 hours, 27 minutes and 33 seconds of flight time. The information comes from Eve Air Mobility, which said the results strengthen confidence in its flight-control models, structural loads, aeropropulsion systems and aircraft behavior ahead of transition flight testing.
The completed campaign covered hover flight and low-speed operations, a phase designed to validate the aircraft’s behavior before the program moves into more complex testing. Eve said the work produced high-fidelity data that will support the continued expansion of the flight envelope.
“The completion of this phase reflects the discipline behind our flight test strategy,” said Johann Bordais, chief executive officer of Eve. “Over 59 flights, we confirmed stable performance and predictable behavior of the control systems within the evaluated envelope, while expanding our understanding of structural loads, aerodynamics, propulsion and energy management, fundamental elements for the transition phase and for the path toward certification with conforming prototypes.”
During the low-speed phase, the aircraft operated below 15 knots, or about 27.8 kilometers per hour. The tests focused on validating control systems, rotor downwash effects, thermal behavior and the propulsion model.
As the campaign progressed, Eve expanded operations to about 20 knots, or 37 kilometers per hour, of horizontal speed. The aircraft performed simultaneous maneuvers across four control axes, allowing engineers to collect data on aerodynamic models and load behavior.
The company said the prototype completed more than 100 flight-test points during the phase. It also demonstrated autoland for the first time and tested a simplified fly-by-wire mode, a secondary layer of the system designed to operate when the primary mode is unavailable.
The aircraft reached 215 feet above ground level, or about 65.5 meters, and remained airborne for as long as 3 minutes and 48 seconds. Eve said noise levels stayed within expected ranges, while propulsion and battery performance exceeded initial projections.
“The completion of the tests provides us with highly reliable data to validate and refine our aerodynamic, propulsion and structural-load models,” said Marcelo Basile, Eve’s head of testing. “This correlation between models and real behavior is what allows a disciplined expansion of the flight envelope. With ground tests planned for the next phase, we will be prepared to begin transition flights, in which we will validate the synchronization between lift and pusher propellers before advancing to cruise flight.”
The next stage will include planned ground testing in preparation for transition flights, which are scheduled to begin in the second half of 2026. That phase will be used to validate the shift toward wingborne flight and further support development of the final aircraft.
Eve, listed in New York and São Paulo, is developing an urban air mobility ecosystem that includes its eVTOL aircraft, service and support networks, and an air traffic management solution.
