Air Taxis Are Safe—According to the Manufacturers

But what keeps an eVTOL aloft when things go wrong?

Joby Aviation is planning for a 240-kilometer range with its piloted aircraft, carrying up to four passengers.

Electric vertical take-off and landing (eVTOL) aircraft for urban commuting are currently under development by more than a dozen different companies. 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.

Rohde & Schwarz

This paper describes the emerging infrastructure trends of wireless networks for 4G, 5G, and beyond 5G. These trends provide even more opportunities to service providers for network deployments, network customization, and network optimization. These key trends include (i) spectrum trends, (ii) densification & coverage extension methods, (iii) virtualization and cloudification, and (iv) network customization and intelligence.
