The Future of Electric Aircraft
The aviation industry has long sought to create an aircraft that takes off and lands like a helicopter, but also sails like an airplane and uses battery power instead of traditional fuel. With the rise of air taxi startups like Archer Aviation in the United States, that long-held dream is inching closer to becoming a reality. However, the process of building, certifying, and flying such an aircraft remains complicated, uncertain, and costly.
The Quest to Revolutionize Air Travel
Electric aircraft, once seen as a distant possibility, are now a hot topic in the aviation industry. With more than 100 flying taxi projects currently in progress, the companies involved hope to make air travel more affordable, accessible, and convenient. Such an undertaking is not without its challenges, however. Some of the biggest roadblocks include:
– Building and maintaining necessary infrastructure
– Ensuring quiet operation in crowded cities
– Gaining public acceptance
– Regulating air traffic control and congested airspace
– Encouraging mass adoption
Despite these challenges, electric-powered air taxis are inevitable. As Mike Leskinen, the president of United Airlines Ventures, stated in a recent article, “It’s a matter of when, not if.” In this article, we will explore the major contenders in the electric aircraft industry and examine their prospects for revolutionizing air travel.
The Contenders
United Airlines and Archer Aviation are two of the biggest names in the electric aircraft market, but they are hardly alone. Many other companies, both start-ups and established players, have entered the domain of battery-powered air transportation. Here are some of the most prominent contenders:
1. Airbus
Airbus is a leading contender in the “vertical take-off and landing” (VTOL) market. The company is aiming to launch its CityAirbus, a zero-emission four-seater air taxi, within the next few years. The vehicle features eight rotors and is designed to fly distances of up to 80 kilometers (50 miles).
2. Boeing
Boeing is one of the oldest and most respected names in aviation. The company recently bought out Wisk Aero, a start-up that specializes in building electric, autonomous aircraft. Boeing plans to unveil the next-generation vehicle developed by Wisk Aero at the Paris Air Show.
3. EHang
EHang is a Chinese start-up that is well-known for its autonomous flying taxis. The company’s flagship product, the EHang 216, is a two-seater aircraft that uses 16 rotors to fly through the skies. EHang has established itself as one of the most innovative players in the space, with several successful test flights already under its belt.
4. Joby Aviation
Joby Aviation is a California-based start-up that has developed a quiet, all-electric aircraft that features minimal operational costs and zero emissions. The vehicle is designed to take off and land vertically, like a helicopter, and then transition to conventional flight mode for longer journeys. The aircraft has a range of up to 240 km (150 miles) and can carry four passengers and a pilot.
5. Lilium
Lilium is a German-based start-up that is currently testing a five-seater electric air taxi that can take off and land vertically. The vehicle is designed to fly up to 300 km (186 miles) on a single charge and is initially targeted at commuters and business travelers. Lilium has raised more than $375 million in funding so far and is one of the most well-funded players in the electric aviation space.
The Challenges Ahead
Despite the many exciting developments in electric aviation, many significant obstacles remain before this technology becomes a widespread reality. Some of the biggest hurdles include:
1. Cost
Developing and certifying an electric aircraft is expensive. The aviation industry estimates that the process can cost up to $1 billion in total. To recoup this investment, electric aircraft manufacturers will need to price their products at a level that is attractive to consumers yet profitable for businesses.
2. Certification
To be operational, electric aircraft must undergo certification by regulatory bodies such as the Federal Aviation Administration (FAA). This is a long and complicated process that includes everything from rigorous testing to demonstration of safety. Companies involved in building electric aircraft will need to demonstrate both technological capability and sufficient capital to pass certification.
3. Infrastructure
Electric aircraft require specialized infrastructure to recharge their batteries and maintain smooth operations. This infrastructure is not yet in place, meaning that electric aircraft manufacturers will need to build it themselves. The costs associated with this could deter some companies from entering the market.
4. Public Acceptance
One of the biggest obstacles to mass adoption of electric aircraft is the public perception of them. To convince people that electric air taxis are a safe, reliable, and comfortable way to travel, manufacturers must prioritize design and engineering.
5. Regulations
Finally, regulations remain a significant challenge when it comes to electric aircraft. Integrating new technology into congested airspaces and managing air traffic effectively will require careful consideration and planning. Companies will need to work with local and national governments to create policies that promote the safe and efficient operation of electric aircraft.
The Summary
Electric aircraft, long a dream of scientists and engineers, are becoming a reality. With many start-ups and established companies getting involved, battery-powered air taxis will change the way people travel for the foreseeable future. However, several challenges remain, including high costs, certification, infrastructure, public acceptance, and regulations. Fortunately, with the level of investment and innovation in the industry, it appears that many of these challenges will be overcome in the years to come. As electric aircraft become more prevalent, air travel will become more affordable, efficient, and eco-friendly, leading to a future in which anyone can take the skies with ease.

A sleek electric aircraft in United Airlines’ familiar blue and white livery is ready to roll. Take off vertically, soaring above the busy city streets, hurtling towards the Manhattan skyline.
This is just a CGI-animated marketing video for now, but United and Archer Aviation, an air taxi start-up, say it will become a reality in two years, with a four-seat vehicle making regular shuttles between the company’s hub aerial to Newark and downtown New York. The companies say the trip, which can take more than an hour by car or public transit, will take 10 minutes and cost about $100 per passenger.
Companies around the world are getting closer to the dream: a battery-powered aircraft – the industry doesn’t like the term “flying machine” – that takes off and lands like a helicopter, sails like an airplane and is blessed by regulators for use commercial. Backers include big names like Boeing and automaker Stellantis, and several companies are aiming for 2024 or 2025 for entry into service.
Yet the journey to build, certify and fly such an aircraft remains costly, uncertain and competitive. Industry estimates peg the cost of development to certification at around $1 billion. Those that are successful will need to demonstrate both technological capability and sufficient capital, and give regulators enough confidence to certify their planes as safe. So they need to price their offering at a level that will get the public to jump on board.
Proponents of electric planes promise free travel from the tangles of land traffic that have blighted modern cities. But there will be challenges, such as building the necessary infrastructure, ensuring quiet operation in crowded cities, and gaining public acceptance.
“We’re going to have a vehicle that has great utility for flying people 50 miles and fewer trips,” says Mike Leskinen, president of United Airlines Ventures, the airline’s venture capital arm, who backed Archer.
“The bigger question is, how do we get the FAA [Federal Aviation Administration] to certify, how can we make sure that [air taxis] do they have the same level of safety as commercial aircraft, how do we integrate that into congested air traffic control and congested airspace? These are the biggest gating elements of “is the aircraft capable?”
“It will change lives,” he adds. “It’s a matter of when, not if.”
After years of promises and milestones missed, the industry is approaching a tipping point. The next 18 months will be critical as several contenders ramp up flight test programs crucial to gaining regulatory certification, straining their resources. Some may need to re-tap investors ahead of launch at a time when much of the recent enthusiasm for tech stocks has waned. Others may not exceed regulatory limits. In a crowded field, not everyone will survive.
“The people who are really promoting this concept of air mobility are visionaries,” says John Cox, an aviation safety expert and former airline captain. “They are very futuristic and . . . there is naivety there.
The visionaries, he adds, are about to encounter “the cold, harsh reality of our national airspace system and national safety regulations, and that fusion will be challenging.”
Some of the contenders
The idea of flying taxis has been around for more than a century. In 1926, Henry Ford introduced the Ford “Fliver”, a flying car for the masses that was supposed to do for aircraft what the Model T had done for automobiles. It failed to enter production after a fatal test flight. There have been other examples along the way.
The major players today are spread across the United States and Europe, with contenders also located in China and Brazil. Some are start-ups, others are backed by industry incumbents such as Airbus, Boeing and Embraer. Boeing, which recently became the sole owner of California-based Wisk Aero, will unveil the company’s next-generation vehicle at next week’s Paris airshow.
Each of these vehicles will need to be certified by regulators in their home country, but unlike traditional aircraft, this does not guarantee they will be declared safe to fly in other regions.
Companies planning to introduce electric vertical take-off and landing (eVTOL) aircraft within three years have adopted three vehicle types: multicopters, thrust vectoring and lift plus cruise.
Multicopters look more like helicopters. They have no wings, fly a shorter range, are simpler to manufacture, and industry considers them easier to certify.
The other two configurations combine rotors and wings. A lift-plus-cruise vehicle uses one set of rotors to lift itself into the air and another set to reach its destination. A thrust vectored air taxi uses a single set of rotors: They lift the aircraft off the ground, then bank to propel it forward.
