A dual-seat, self-piloting electric vertical takeoff and landing (eVTOL) aircraft from EHang represents a vision shared by many startups: that electric air taxis will fill low-altitude skies within the next few years. If this becomes reality, a critical question emerges: how will these numerous aircraft avoid colliding with each other? The answer, according to several flying taxi CEOs, lies in autonomous flight. They argue that an automated system is far more capable of safely managing dense air traffic than a human pilot.
If this vision materializes, it would also push ground transportation closer to a fully autonomous era, as car manufacturers and ride-hailing platforms are already expanding driverless services. While self-driving cars have entered commercial use in several cities, replicating this model in U.S. airspace presents a far greater challenge. American regulators have spent years reviewing airworthiness certifications for piloted electric air taxis and have yet to issue any operational licenses. It is reasonable to expect that approval standards for fully autonomous aircraft will be even more stringent.
Beyond regulatory hurdles, even if certification is obtained, the general public may resist boarding a flight without a pilot. China has already taken the lead in launching autonomous passenger flights. Earlier this year, EHang began operating a fixed, short-distance commercial passenger route using its EH216-S, a two-seat, self-piloting eVTOL. Chinese authorities have placed strict limits on EHang's flight paths, ensuring the eVTOL does not enter airspace used by other aircraft. Despite these restrictions, launching commercial operations is a bold move, consistent with the company's history. Before starting commercial service last year, EHang invited journalists and social media influencers for test flights, a risk no other eVTOL company in the U.S. or Europe has taken. EHang is also currently pursuing airworthiness certification for this model in Mexico.
In recent years, significant capital has flowed into U.S. companies developing piloted eVTOLs, with billions of dollars in funding raised by startups like Joby Aviation, Archer Aviation, Beta Technologies, and the UK-based Vertical Aerospace. The push for aviation autonomy began in the defense sector, and these companies will need to raise billions more to complete the transition. Earlier this month, several European and U.S. eVTOL startups gathered at the Farnborough International Airshow near London, showcasing modified eVTOL and hybrid models aimed at securing contracts from the U.S. Department of Defense and the British military. Most of these aircraft are designed for fully autonomous flight, or offer both piloted and self-piloted versions. However, military autonomous drones are vastly different from civilian passenger aircraft. The U.S. is currently focused on developing and deploying large, pilotless electric drones, and the Federal Aviation Administration (FAA) does not regulate military aircraft.
John Bordais, CEO of Eve Air Mobility, an eVTOL subsidiary of Embraer, stated that the technology for autonomous air taxis already exists. However, the entire aviation ecosystem, including many older piloted aircraft, must be updated before autonomous flight can be commercially viable on a large scale. Such upgrades are unlikely in the short term. He proposes a transitional path where pilots remain in the cockpit, but the aircraft's computer handles the most difficult tasks: takeoff and landing. The current air traffic control system, designed for traditional airliners, cannot integrate with autonomous flight paths. This integration will only be possible as older planes are gradually retired, allowing for a network of low-altitude eVTOL routes connecting city centers, airports, and suburbs.
"How do we safely integrate fully autonomous aircraft into an airspace still filled with 30-year-old piloted planes?" Bordais asked. "The old planes will eventually be retired. Only after that step can we safely fly large numbers of autonomous aircraft."
eVTOL companies are heavily investing in autonomy for reasons of safety and profit. Pilots represent a significant cost, including salary and benefits, and the space required for a cockpit reduces passenger capacity. Bordais noted that removing the pilot's cockpit would allow Eve's eVTOL to increase its capacity from four to six passengers, a 50% gain. "Higher passenger revenue allows for more affordable ticket prices," he said.
David King, chief engineer at Vertical Aerospace in the UK, proposes a different path to accelerate autonomy: completely isolate eVTOL routes from other civilian airspace. This would involve creating a separate control system, independent of the current FAA system. In this model, eVTOLs would fly autonomously at a fixed low altitude, while other airliners operate at higher altitudes, creating separate, non-conflicting lanes. "Controlling low-altitude aircraft would no longer rely on the traditional air traffic control infrastructure and personnel designed for major hub airports," King explained. "The low-altitude space could be managed independently, with integration into the broader airspace happening later."
Regardless of the chosen path, eVTOL companies must overcome the significant challenge of convincing the American public to fly in a plane without a pilot. "No city is going to simply approve autonomous air travel overnight," Bordais said. "You need to accumulate enough safety data and prove reliability before you can truly remove the pilot."
