MELBOURNE, Fla. – Eve Air Mobility in Melbourne, Florida, recently completed hover and low-speed flight testing of its full-scale electric vertical takeoff and landing (eVTOL) aircraft prototype. This move marks a milestone in the company's effort to validate flight controls, propulsion systems, and aerodynamic performance ahead of transition flight testing.
The completed test series included 59 flights and more than 100 flight-test points. Engineers used the campaign to compare aircraft behavior against computer models and simulations that support vehicle development and certification activities.

Flight controls and low-speed envelope expansion
Flight-test teams gradually expanded the aircraft's operating envelope while evaluating handling qualities and system performance during increasingly demanding maneuvers. The campaign began with operations below 15 knots before expanding to approximately 20 knots while performing simultaneous control inputs across multiple flight axes.
Engineers examined flight-control responses, aerodynamic loading, thermal behavior, and downwash effects generated by the aircraft's electric propulsion system. Researchers will use the data collected during the campaign to refine engineering models and support upcoming test phases.
The aircraft also completed initial demonstrations of automated landing functions and a backup fly-by-wire operating mode designed to maintain controllability if the primary control configuration becomes unavailable.
Transition flight preparation and aircraft development
Hover testing represents an early phase of eVTOL development because aircraft rely primarily on vertically oriented propulsion systems rather than aerodynamic lift generated by the wings. Transition flight introduces additional complexity as control systems coordinate propulsion and aerodynamic surfaces while shifting from vertical flight to forward wingborne operation.
Eve said the prototype reached an altitude of 215 feet above ground level during testing and recorded flight durations approaching four minutes. The company also reported motor and battery performance that exceeded preflight expectations.
The next phase of the program will include ground testing before transition-flight evaluations begin later this summer. Those tests will focus on coordinating the aircraft's lift and cruise propulsion systems as engineers prepare for conventional wing-supported flight.
“Completing hover and low-speed testing gives us high-confidence data to validate and refine our aerodynamic, propulsion and load models,” said Marcelo Basile, head of tests at Eve.
