A: An Electric Vertical Take-Off and Landing (eVTOL) aircraft is designed to take off and land vertically, similar to a helicopter. Still, it uses electric propulsion systems for propulsion and lift. Electric motors and batteries often power these aircraft, which are intended to provide more environmentally friendly and efficient urban air transportation.

Critical characteristics of eVTOL aircraft include:

  1. Vertical Take-Off and Landing: eVTOL aircraft can take off and land vertically, eliminating the need for traditional runways or airports. This capability allows them to operate in congested urban areas with limited space.
  2. Electric Propulsion: These aircraft use electric motors, often powered by lithium-ion batteries, to generate lift and propulsion. Some eVTOL designs also incorporate hybrid powertrains.
  3. Distributed Electric Propulsion: Many eVTOL aircraft feature multiple electric motors distributed across the airframe, providing redundancy and enhancing safety. These motors are often mounted on rotors or ducted fans.
  4. Quiet Operation: Electric propulsion systems are quieter than traditional internal combustion engines, which can help reduce noise pollution in urban environments.
  5. Autonomy and Automation: Many eVTOL designs incorporate advanced automation and autonomous flight capabilities, enabling them to operate with minimal pilot intervention.
  6. Short to Medium Range: eVTOL aircraft are typically designed for short to medium-range missions, making them suitable for urban air mobility (UAM) applications, such as air taxis and on-demand aerial transportation services.
  7. Sustainable Transportation: Using electric propulsion in eVTOL aircraft is considered more environmentally friendly, as it produces fewer emissions than conventional fossil-fuel-powered aircraft.

These aircraft have gained significant attention in recent years as companies and startups work on developing them for a range of applications, including urban air taxis, cargo transportation, medical evacuations, and more. Currently planning on manufacturing in Ohio, Joby Aviation Inc is building a $500 million factory in Dayton to produce electric vertical take-off and landing (eVTOL) aircraft. The facility is scheduled to open in 2025.

The eVTOL industry is still in its early stages, and many companies are actively working on prototype development, certification, and infrastructure development to make urban air mobility a reality in the future.
