These concepts and prototypes, representing well over a billion dollars of venture capital investment in 2020 alone, promise that sometime in the near future, point-to-point travel between suburbs and urban centers will happen by air using innovative new flying vehicles that are fast, quiet, clean, and far more affordable than a helicopter. United Airlines has ordered 200 eVTOLs. American Airlines has ordered 250, with an option for 100 more. But none of these eVTOL platforms are yet certified to carry passengers, and as a fundamentally different approach to flight, there are still open questions about safety.
A significant difference in safety that separates many eVTOL designs from traditional aircraft (namely, airplanes and helicopters) is that eVTOLs often don't have a good way of passively generating lift in the event of a power system failure. An airplane can rely on its wings to provide lift even if it has no operational engines, and in several cases, large passenger airliners with multiple engine failures have been able to make controlled long-distance glides to land safely. Similarly, helicopters can autorotate, using the unpowered rotor to generate enough lift to make a controlled descent and landing.
EVTOLs typically rely either entirely or in large part on distributed propulsion systems—many small electric motors driving propellers or fans that together generate lift. Some eVTOLs have wings, but those wings are not necessarily designed to facilitate landings. And some eVTOLs rely exclusively on powered lift systems, meaning that if a software or hardware failure disables the entire power system, the vehicle can no longer generate any lift at all. It's a scary thought, and the companies developing eVTOLs are well aware that in order to be successful, they'll have to achieve a level of safety that inspires confidence from both regulators and future passengers.
An electric vertical take-off and landing (eVTOL) aircraft use electric power to hover, take off, and land vertically. This technology came about thanks to major advances in electric propulsion (motors, batteries, fuel cells, electronic controllers) and the growing need for new vehicles for urban air mobility (air taxi). Examples are being developed by aircraft companies such as Boeing, Airbus, Embraer, Honda, Toyota, Hyundai, and NASA.
