All Electric Plane can fly with 9 passenger 2 crew

This is the world’s first full-sized all-electric passenger plane. Her name is alice now she isn’t the first attempt at an electric passenger plane previous attempts looked like a glider or an old seaplane retrofitted with an electric engine, but alice is different, the aviation alice is nine passenger two crew all-electric commuter aircraft. This aircraft is built from the ground up to be electric. It’s not a conversion of anything. Israeli aeronautics company aviation started work on alice back in 2015 and debuted the plane in june 2019 its goal to find a sustainable way to move people regionally air travel is one of the fastest growing contributors to climate change and even mid pandemic when travel has dipped the airline industry’s carbon footprint is still outpacing predictions regional travel is a big component of that footprint in 2017 half of the 4 billion air tickets sold were for regional flights even though these were short distances the aircraft used were huge jet planes built across oceans that’s an insanity because we’re using the wrong tools for the job

alice might be a solution for these popular commuter routes think new york city to dc or even up the

west coast between san jose and san diego the plane

is built to fly up to 650 miles on just one charge of its lithium-ion battery the distance from london to prague

and it’s designed to carry passengers atcruising speeds of about 276 miles per hour now that’s about half as fast as jet fuel planes so a one-hour 10-minute flight from new york city to dc would be about two and a half hours on alice but alice could do that journey emissions-free it seems ideal but engineers faced a few challenges while building alice it has a huge battery we have roughly 3.6 metric tons of battery over 8 000 pounds in electric cars a battery’s weight isn’t as much of an issue because cars stay on the ground but in a plane trying to get in the air with a heavy battery becomes a challenge the bigger the battery the more power for the plane but a bigger battery also means more weight to lift so more power is needed to get it in the air in normal airplanes an estimated 30 of the plane’s maximum takeoff weight is jet fuel and that weight lessens over time as jet fuels burned while in the air but for alice we’re roughly at 60

percent of maximum takeoff weight meaning 60 of the plane when it takes off is battery it’s the same when it lands we don’t lose anything so aviation had two solutions for a heavy battery engineers distributed the battery throughout the plane that battery is literally all over the place it’s under the floor it’s in the wings in the fuselage in different locations then they balanced out the battery’s sheer weight the way to do it is just to build everything else very light alice has a lightweight airframe slim wings and wingtip propellers it has  a lifting body which means it looks like a for lack of a better description an upside down boat all of those features were built to create a more efficient airframe at cruise another key feature that sets alice apart is its lift to drag ratio or how much lift the wing generates compared to how much drag it creates moving through the air a regular plane has a lift to drag ratio of 17 to 1. for alice that rate is 25 to 1 meaning it’s more aerodynamically efficient and uses less energy getting into the air

for future passengers all this environmentally conscious innovation means a lot less traveler’s guilt I think it’s important that the industry looks at its responsibilities of the planet and makes itself more sustainable in terms of

emissions but it needs to work economically some players in the industry say electric planes could mean 40 to 80 percent lower airfares that’s because it doesn’t cost as much to operate an electric plane aviation’s alice costs about 200 per flight hour to operate a similarly performing turbo prop would cost between 1200 and 2000 per flight hour but in order to be truly sustainable omer says people have to actually want to fly electric this needs to feel like a plane you want to use daily so how does alice do that designers wanted the windows to be big enough to increase visibility and they added stability technology to help with turbulence plus alice’s electric engine is practically silent this plane is dramatically less noisy about two orders of magnitude less noisy than an equivalently sized aircraft I think it could change the way we treat airports despite testing

hiccups in early January omer estimates the plane will be certified by 2022 us-based airline cape air has already decided to buy the aircraft at 4 million dollars per plane the airline plans to introduce alice into its fleet

serving regional routes from boston to Nantucket martha’s vineyard and up into new hampshire and New York in the very beginning it was extremely difficult to convince partners clients anybody investors that were not delusional today it feels like everybody is on board

and this is where the industry should go the industry is beginning to notice that there is really a tectonic shift

here.
