What are air taxis?
The genesis of air taxis took root with helicopter services that operated primarily in the 1950’s and 1960s, transporting passengers across US, European and Australian cities. Initially, these scheduled air taxi operations flourished, airlifting hundreds of thousands of passengers and, in 1951, The Wall Street Journal proclaimed that “the age of aerial taxis is here”. However, economics and safety complexity tempered the advance of such services.
Today, air taxis are a mode of transportation that intends to use small, electric vertical takeoff and landing (eVTOL) aircraft to provide on-demand passenger services. These taxis are designed to carry a few passengers and offer a convenient way to travel short to medium distances within urban or suburban areas.
Their chief purpose is to alleviate traffic congestion and reduce travel time for commuters while reducing emissions.
How do they work?
Air taxis use innovative technology that combines vertical takeoff and landing capabilities with electric propulsion systems.
These vehicles are designed to provide efficient and convenient urban transportation solutions as they can take off and land vertically, eliminating the need for long runways.
eVTOL air taxis are powered by electric motors, which are more environmentally friendly and quieter than conventional combustion engines. Many eVTOL designs feature multiple rotors or propellers distributed across the aircraft’s frame, ensuring stability and precise control during flight.
These aircraft rely on advanced lithium-ion batteries to store and deliver electric power, allowing for sufficient range and performance.
What types of aircraft could be used as air taxis?
Air taxis come in various configurations that have the potential to cater to the evolving demands of urban transportation.
These configurations include multirotor VTOL aircraft, such as quadcopters, hexacopters, and octocopters, which offer stability and redundancy, making them suitable for urban air mobility. VTOL aircraft produce vertical thrust for take-off and landing and are capable of hovering, but then they transition to horizontal thrust for flight operations.
Some eVTOLs feature fixed wings in addition to rotors, combining the efficiency of fixed-wing flight with the versatility of vertical takeoff and landing. Tilt-rotor and tilt-wing eVTOLs balance vertical and horizontal flight capabilities with the ability to transition between modes.
Electric helicopters designed for urban air mobility bring the familiar hovering capability of helicopters while using electric propulsion for reduced noise and emissions.
Hybrid VTOL aircraft combine electric propulsion with a combustion engine or generator, which currently results in higher top speeds and extended range.
What is the difference between autonomous and piloted air taxis?
Depending on the design, air taxis may operate autonomously or with a pilot on board. Autonomous air taxis are equipped with advanced computer systems, sensors, and navigation and obstacle avoidance software.
What are the benefits of air taxis over traditional transportation?
The promise of air taxis is to reduce traffic congestion by bypassing crowded roads and highways, leading to faster and more efficient commutes. These taxis would save valuable time for commuters navigating congested urban areas, resulting in increased productivity and improved overall well-being.
Their ability to provide direct point-to-point travel could eliminate the need for multiple transfers or stops, streamlining the travel experience. Their flexibility and accessibility, thanks to a network of vertical takeoff and landing sites, could promote inclusivity and efficient transportation within cities.
Additionally, air taxis could factor into environmental sustainability efforts, producing fewer emissions than traditional internal combustion engine vehicles, making them an eco-friendly choice that improves urban air quality.
eVTOL aircraft deployed as air taxis would also be quieter than helicopters and traditional airplanes, reducing noise pollution in densely populated urban regions.
Lastly, air taxis require less physical space for takeoff and landing, contributing to efficient land use and potentially reducing city infrastructure expenses. These benefits make air taxis a promising solution for addressing urban transportation challenges.
When should we expect to see air taxis in use?
Regulatory bodies, like the Federal Aviation Administration (FAA) in the United States and their counterparts in other countries, are crucial in establishing safety standards and guidelines for air taxi operations.
Currently, the FAA’s pathway to advanced air mobility is ramping up. In July 2023, the FAA released an Implementation Plan to safely enable advanced air mobility in the near term.
Infrastructure development, including the construction of vertiports (air taxi takeoff and landing sites) and charging infrastructure, is another crucial factor influencing the timing of air taxi adoption. Cities and regions will need to invest in the infrastructure required to support these new modes of transportation.
Public acceptance and willingness to embrace air taxis as a reliable and safe means of transportation will also play a vital role in determining their adoption rate. Education and outreach efforts can help build trust and understanding among potential users and community members alike.
Projections from experts
According to the FAA timeline, electric air taxis could start flying by 2028. Some McKinsey experts believe we will see these aircraft within the next decade, and another aviation expert thinks the 2028 Olympics in Los Angeles will be an excellent opportunity to showcase in-development electric air taxis.
Ultimately, air taxis may be closer than we think, but will still likely take many years to become widespread in use.
How are governments preparing for their arrival?
The FAA is developing and releasing timelines, working with the aviation industry to make realistic and needed preparations for the use of air taxis.
Are regulatory challenges holding up deployment?
The U.S. Department of Transportation’s Office of Inspector General says the FAA has struggled to set certification procedures for eVTOL aircraft, delaying rulemaking and hindering certification. This opinion was released in a report in June 2023.
The report states that the FAA made limited progress over four years in determining which certification path to use for eVTOL.
One obstacle stems from over two decades ago, when the FAA defined an aircraft category called powered-lift. This category applies to some advanced air mobility aircraft but did not establish corresponding airworthiness standards and operational regulations.
The DOT report stated that the continued ineffective coordination and communication, lack of timely decision-making and unestablished policies could further hinder progress.
In July 2023, The FAA released its implementation plan (PDF), including a proposed rule for training and certifying pilots as well as a final rule that updates the air carrier definition to add powered-lift operations to the regulations covering other commercial operations, such as airlines, charters, and air tours.
What technologies are needed for air taxi infrastructure?
Along with previously mentioned vertiports, efficient air traffic management is paramount, necessitating technologies like UAS Traffic Management (UTM) systems and urban air mobility traffic management solutions to ensure safe separation between air taxis, drones, and other aircraft.
Reliable and secure communication networks are also needed, enabling seamless coordination with air traffic controllers and other aircraft. Precise navigation and positioning systems such as GPS, Lidar, and radar are vital for accurate flight paths and obstacle avoidance.
Electric charging infrastructure, grid integration, and advanced avionics are required to power and manage air taxis effectively.
Maintenance and inspection technologies, noise reduction measures, and robust security and safety systems are also critical for the reliable and secure operation of air taxi infrastructure.
What are some challenges to development?
Noise: Noise generated by electric-powered air taxis, particularly during takeoff and landing, will likely be a concern in urban environments, though these aircraft are much less noisy than traditional aircraft.
