MELBOURNE, Fla. – October 31, 2026 -- Eve Air Mobility (NYSE: EVEX, EVEXW; B3: EVEB31) has closed the hover and low-speed block of its full-scale engineering prototype flight test campaign after 59 successful flights and 2:27:33 of accumulated flight time. The company expects transition flight testing to begin in summer 2026, in July or August.
Prototype executes more than 100 test points and reaches 215 feet
The block produced more than 100 flight test points. The aircraft reached 215 feet above ground level and flew for 3 minutes and 48 seconds. Eve also completed the first demonstrations of autoland and of the simplified fly-by-wire mode, a secondary layer of the fly-by-wire system that activates when the normal mode is unavailable.
Noise levels remained in line with expectations. Propulsion and battery performance were better than anticipated, according to the company.
Eve expands testing from 15 knots to roughly 20 knots ground speed
The team first completed a low-speed input phase below 15 knots. That phase validated control laws, downwash effects, thermal behavior and the propulsion model. Operations then expanded to approximately 20 knots of ground speed, including simultaneous four-axis maneuvers intended to validate aerodynamic and load models. The aircraft showed consistent behavior under those simultaneous inputs.
Eve describes its approach as a building-block strategy. It widens the flight envelope step by step and checks models and control laws against flight data before moving to more complex tests.
Management ties data to certification path with conforming prototypes
CEO Johann Bordais said the 59 flights confirmed stable hover performance and predictable control behavior within the envelope. He said the results also deepened understanding of loads, aerodynamics, propulsion and energy management, which he called foundations for the transition phase and the certification path with the conforming prototypes.
Marcelo Basile, Head of Tests, said the data will be used to validate and refine the aerodynamic, propulsion and load models. He said model correlation enables the envelope expansion.
Ground tests precede transition flights targeting lifter-pusher synchronization
Over the coming weeks, the engineering prototype will undergo planned ground tests ahead of the transition flights block. In that block, Eve will validate lifter-pusher synchronization before moving on to the cruise phase. The transition phase is designed to support development of the final aircraft as the program advances toward wingborne flight.
