The Alice, a plane developed by Israeli company Eviation, went through engine testing last week at Arlington Municipal Airport north of Seattle. According to Eviation CEO Omer Bar-Yohay, the Alice is just weeks away from its first flight.
With battery technology similar to that of an electric car or a cell phone and 30 minutes of charging, the nine-passenger Alice will be able to fly for one hour, and about 440 nautical miles. The plane has a max cruise speed of 250 kts, or 287 miles per hour. For reference, a Boeing 737 has a max cruise speed of 588 miles per hour. The company, focused exclusively on electric air travel, hopes that electric planes that can fit 20 to 40 passengers will be a reality in seven to 10 years.
A prototype of the aircraft, which debuted in 2019, has been going through low-speed taxi tests since December and will attempt a high-speed taxi test in the next few weeks. In these tests, the aircraft is sent down the runway at different speeds to test its own power and allow ground teams to monitor systems like steering, braking and anti-skid. Though the company initially aimed for the Alice to take flight before 2022, poor weather conditions in the Pacific Northwest at the end of the year hindered testing.
Eviation has developed three versions of the prototype: a “commuter” variant, an executive version, and one specialized for cargo. The commuter configuration in testing holds nine passengers and two pilots, as well as 850 pounds of cargo. The executive design has six passenger seats for a more spacious flight, and the cargo plane holds 450 cubic feet of volume.
All of this is possible while reducing maintenance and operating costs of commercial jets by up to 70%, according to the company.
According to industry experts, the largest obstacle for electric aviation becoming the norm in passenger jets is the battery.
“The stumbling block is the battery technology just like with cars, but more so in airplanes. This is because with airplanes, the concern is the weight,” said Ross Aimer, CEO of Aero Consulting Experts. “As soon as we have better battery technology, which I suspect will be in two or three years, that’s when all these electric airplanes will eventually come.”
Twelve Alices are on order by international shipping company DHL, anticipated to be delivered in 2024. These planes, out of DHL Express’s global fleet of more than 280 aircraft, are set to be used as cargo carriers making shorter distance trips. “Our aspiration is to make a substantial contribution in reducing our carbon footprint, and these advancements in fleet and technology will go a long way in achieving further carbon reductions,” said Mike Parra, CEO of DHL Express America, in an interview with CNN Business.
