Sept. 27, 2022 © Leeham News: The battery-powered Eviation Alice has flown for the first time.
The nine-seat aircraft, powered by twin electric propeller motors assembled by Eviation’s sister company, magniX, rotated up and took off into a sky hazy from forest fires shortly after sunrise in the Pacific Time Zone, a little after 7 a.m.
After takeoff the plane banked to the right, circled for eight minutes around Grant County International Airport in Moses Lake, then landed safely. The Alice reached an altitude of 3,500 feet.
The dawn flight was an important milestone for Eviation, magniX, and for battery-powered aircraft in general. The Alice appears to be the largest electric passenger aircraft to fly so far, larger than the two-seater Pipistrel Velis, which had its first test flight with passengers in Iceland last month. Tecnam and Rolls Royce teamed up to fly a four-seater P2010 with a hybrid electric engine in February.
Summary
In a statement released just after takeoff, Eviation said the flight is the dawn of a “new era of more sustainable, scalable and affordable transportation.”
Some 30% of passenger flights cover less than 250 nautical miles, the company said. These flights emit far more carbon on a per-passenger-mile basis than long-haul flights, and the Alice will be a “catalyst for making these flights environmentally sustainable.”
The Alice also is 20% to 30% quieter than conventionally powered aircraft, which will make it possible for use at more regional airports with current noise restrictions.
The Alice is being sold with commuter, cargo and VIP versions, Eviation said. In a press release following the flight, the company noted that it has agreements with two passenger carriers — Cape Air and Global Crossings — for a total of 125 of the commuter models, and an agreement with DHL Express for 12 of the cargo version.
Eviation and magniX still face significant challenges to getting the Alice into service, particularly when it comes to the batteries that will power the electric motors, Eviation CEO Gregory Davis said in a post-flight press conference.
“The biggest technical challenge that Eviation has to overcome is the development of batteries,” he said. “We really do need the industry to boost the energy density.”
Because of that, Davis said he doesn’t expect that Alice will win regulatory approval until 2025, and won’t be carrying paying passengers until 2027.
In addition, the companies would greatly benefit from a battery manufacturer taking the lead to develop batteries specifically for aviation applications, he said. To this point, magniX and Eviation have adapted existing batteries to meet their needs.
Davis said he’s optimistic that battery improvements are coming, mentioning 3D-printed solid state batteries as one potential future option. “There are some fairly promising chemistries out there,” he said, along with “block changes in the way that batteries will be built, which will help us.”
Increasing demand for high-capacity batteries in many industries will help Eviation and magniX, he said. “The indications are that the market is driving that technology.”
Getting the aircraft certified is another challenge, Davis acknowledged.
Right now, there isn’t “unity,” he said, between the FAA and EASA in terms of battery certification standards.
The plane that flew this morning was Eviation’s “proof of concept” aircraft, Davis said. With a five-year gap before the expected entry into service, and with technologies developing rapidly, “we absolutely will make evolutions to the aircraft,” he said.
The first plane will be one of three that Eviation anticipates using for certification program, he said, adding he anticipates they will need 1,500 to 2,500 hours of flight time before getting regulatory approval.
The Alice is the clean-sheet electric aircraft from Eviation. Harbour Air, a seaplane carrier based in Vancouver, Canada, has been testing a six-passenger de Havilland Beaver retrofitted with an electric motor built by magniX. Last month, it completed its first point-to-point flight, a 45-mile hop between Vancouver and Victoria.
Today’s first flight for the Alice flight came after a series of false starts. Eviation and magniX debuted the Alice at the Paris Air Show in 2019. Then it was conceived as a tri-motor, a concept that was scrapped as magniX developed more-powerful electric motors. The original V-tail also gave way to a more conventional T tail.
Last year, the companies announced their intent to fly the Alice for before the end of 2021. In January, the companies said the first flight was only “weeks away.” But a series of personnel changes at the top then occurred, including the departures of Roei Ganzarski, who was both CEO of magniX and chairman of Eviation, and the firing of Omer Bar-Yohay, Eviation’s CEO.
Both Eviation and magniX are owned by Singapore-based Clermont Group.
Are the batteries in the back? In the wings?
Congrats to the team, much success in future testing.
We’re going to have to come up with distinct names.
Hmm, I will go with williams then
Our understanding is that the batteries are packed into the hull under the floor.
Yes.
This video from Eviation of the high speed taxi and rotation run shows the half circular upper fuselage with the flattened floor shape to good effect

Very exciting news!
Congratulations to the team at Eviation!
They left half a ton of passengers behind.
For a prop plane with straight wings the takeoff is more like a B-52, long run and ‘flat climb’
The video of the takeoff- taken outside the airport boundary- gives off a hell of a lot of noise for an all electric plane.
Will Eviation release there own video taken closer to runway of actual takeoff ?
I see a chase plane in the air too
“Eviation and magniX need batteries to get better”
That’s the depressing truth after this great achievement. Certifiable energy intensity bumps aren’t around the corner. No disrupting miracles, promising breakthroughs by small groundbreaking innovators on the radar. This is aerospace, not science fiction.

Interesting graphic, showing that, even with solid-state batteries, the asymptotic limit is still way too low for general replacement of hydrocarbons in aviation.
Anyone has sit down and est. the volume and weight of over 40k battery cells, coolant, inverters and wiring etc??
Just saw an approach video (without voice over & violin music) of the Alice. A turn, lowered landing gear. High frequency prop noise, like a sander.
I realized this aircraft is still at MTOW during approach and needs its propulsion to stay in the air. Not much gliding at idle.
If I’m living in an area close to an airport, this is probably not gonna help me towards a quieter environment.

The “first test flight with passengers” for the Pipistrel last month seems a bit suspect – I saw it on display at Fully Charged Live in May and it had flown there with one of the presenters as a passenger. And in the accompanying video the pilot gave the impression he’d been flying it for a while before that…

Ah… *Icelandair’s* first flight with the Pipistrel. I see.
