Eve 100 eVTOL Set to Make Low-speed Transition Flight

Eve Air Mobility is preparing to make the first low-speed transition flight of its Eve 100 eVTOL in the coming weeks. This milestone, which Eve predicts will happen shortly before the Farnborough International air show in July, will precede a full-speed transition at 90 knots later in the year.

To date, the Embraer spin-off’s full-scale uncrewed prototype has made 59 flights since December 2025. With a total of two hours, 27 minutes, and 33 seconds of accumulated flight time on the clock, the technology demonstrator is currently in a lay-up phase ahead of the next stage of flight testing. This will see it make its first airborne transition from horizontal to vertical flight at up to 50 knots.

After this initial flight envelope expansion, Eve intends to make what it terms a ‘full transition’ at almost twice that speed in the third quarter of the year. “That’s when we’re going to have all the data that we need to transfer to the conforming prototype,” explained Eve CEO Johann Bordais, during a recent media briefing in Brazil.

According to Bordais, the new aircraft will be "very close to a conforming prototype" in terms of the type certification process being worked through with Brazilian civil aviation regulator ANAC. However, he did acknowledge that there could be "a couple of tweaks here and there" before a fully conforming example is produced.

Although he conceded that this upcoming aircraft may potentially include “a couple of tweaks here and there,” he explained that the successor will be “very close to the conforming prototype” the Brazilian civil regulator will be certifying.

In total, the current engineering prototype is expected to make up to 130 flights with a total of some ten hours airborne. While this aircraft’s duration is limited to around seven minutes, the battery system on the next variant—also provided by BAE Systems—will support greater range. During the course of the certification campaign, this will be swapped out once more for a yet more mature battery, intended to offer Eve its projected 85 kilometers (46 nm) of range, with energy reserves.

Type Certification Target

The first of five crewed test aircraft is expected to make its first flight around July 2027. These will be assembled at Embraer’s Ozires Silva plant and transported to the Gavião Peixoto factory for completion. Around 800 Embraer engineers have input into the eVTOL program, something Bordais describes as a “core differentiator” to other eVTOL OEMs.

Eve expects to conclude its flight test campaign in the second half of 2028, prior to Brazilian certification and U.S. validation later that year. Having also applied to EASA during the second quarter of this year, the company expects European certification to follow some 12 to 15 months later after its ANAC and FAA approvals.

For now, Eve is not giving attention to possible hybrid-electric propulsion for its aircraft. “I don’t believe in it, because you’re taking away the big advantage that you have, which is the noise [reduction],” Bordais commented. However, he did concede that for future intercity missions “hybrid could be a solution… it’s just not the focus of Eve right now, but it doesn’t mean we’re not studying possibilities.”

Additionally, Eve has not ruled out potential defense applications for its eVTOL, with Bordais suggesting that Eve could sell a whitetail aircraft to Embraer’s Defense business unit for customization. BAE Systems has also signalled its intention to purchase one for defense-related applications.

Eve’s simulator, which AIN flew during the visit to Brazil, has also evolved along with the aircraft concept. Notably, the throttle position—previously operated with the pilot’s left hand—has been incorporated into the sidestick via a thumb-controlled scrolling wheel. Eve says this is to help reduce workload and also safeguard against potential damage as pilots climb in and out of the aircraft.

There is also no specific transition flight command. Instead, the Eve 100 will be programmed to make the transition based on a pre-determined speed, with the vertically-oriented motors automatically disengaging when the aircraft has sufficient lift for forward flight.
