The Future of Transportation is Taking Flight: Advanced Aerial Mobility


Emerging Technologies are Transforming How We Move Around Cities

Advancements in electric vehicles, batteries and autonomous systems are enabling the development of new forms of air transportation that could revolutionize how people and goods are moved within and between urban areas. Companies worldwide are actively working on aerial vehicles like electric vertical take-off and landing (eVTOL) aircraft and delivery drones that could help alleviate problems like traffic congestion.


Advanced Aerial Mobility is electric vertical take-off and landing aircraft promise quiet, emissions-free flights direct from city center to city center. eVTOLs use electric motors and battery power to hover and fly short to medium distances, typically up to 100 miles. Their vertical take-off and landing capability means they don't need runway infrastructure - they can operate from existing helipads or even the rooftops of buildings. This opens up the possibility of an on-demand urban air taxi service or commuter flights between nearby cities. Numerous companies are developing piloted and autonomous passenger eVTOL concepts. For example, German startup Volocopter conducted the first crewed flight of its electric air taxi in 2017 and has since performed over 1,000 test flights. The Volocopter 2X has a range of 22 miles and can carry two passengers. Other companies like Joby Aviation, Lilium, and Ehang are also developing electric aircraft aimed at an air taxi market. Boeing, Airbus, and Uber are also actively working on eVTOL technology through partnerships or acquisitions. Airspace regulators will need to work closely with these manufacturers to safely integrate eVTOL operations into dense urban environments and existing air traffic systems.


Advancing Drone Delivery

Drones are already delivering goods in parts of the world and their potential is vast. Companies like Amazon, UPS and DHL are using autonomous multicopters to deliver packages on a small scale. However, technical and regulatory challenges remain before drones can realize their full potential to take weight off roads. Larger payload capacity and longer ranges will be needed for drones to efficiently deliver larger shipments between businesses over citywide routes or even between adjacent cities. Advancements in electric propulsion, battery technology, autonomy and payload designs could help unlock drones' wider commercial use within the decade. For example, Singapore-based company Sea-Air Mobility is developing a hybrid drone called the Mayfly that uses electric motors for vertical take-off and cruise then switches to wings for efficient long-range forward flight, enabling delivery ranges of over 60 miles. Companies are also pursuing hydrogen fuel cell technologies as a way to provide drones with far greater energy capacity than current lithium-ion batteries allow. Government policymakers will play a vital role in establishing an appropriate regulatory framework for routine commercial drone operations beyond line-of-sight. Airspace management systems will also need to safely integrate drones with other aircraft. With the right technological and regulatory enablers in place, autonomous cargo drones could carry shipments directly between cities or from ground facilities up to the doors of businesses, reinventing logistics networks.


Charging Infrastructure is Key

One major hurdle for both passenger eVTOLs and cargo drones is establishing the necessary charging infrastructure to power long-term operations. Battery swapping is an option, but building a network of charging pads and stations similar to electric vehicle infrastructure will likely be needed for widespread adoption. The challenges are greater for aerial vehicles which require fast recharging to turn aircraft around quickly for repeated flights each day. Companies are therefore investing in both new battery technologies and charging solutions. For example, BMW is collaborating with partner Kinergy on advanced lithium-ion battery packs optimized for aviation use cases. Charging techniques under development include inductive wireless charging pads much like wireless phone chargers that could recharge eVTOLs on helipads during brief stops. Siemens for instance has demonstrated parking spot-sized inductive charging plates capable of fully recharging electric aircraft in under 30 minutes. Implementing widespread charging networks across cities, transport hubs and logistics facilities will be essential before advanced aerial vehicles can operate at scale. Agreeing common charging standards will also be important to ensure interoperability as the industry progresses. With targeted investments and cooperation between multiple stakeholders, viable charging solutions could soon unlock convenient, low-cost operations for both passenger-carrying eVTOLs and autonomous cargo drones.


Regulatory hurdles remain, but together Emerging Technologies are Priming Cities' Skies for New Transportation Horizons

Technologies are advancing rapidly, but significant regulatory work lies ahead before electric aircraft can safely enter commercial service. Safety certification for piloted and autonomous electric and hybrid vehicles across multiple vehicle classes will be required. Airspace regulations must also be adapted to incorporate urban operations, especially passenger-carrying eVTOL flights with takeoff and landing areas integrated directly in cities. Progress is being made through collaboration between manufacturers, regulators and legislators however. For example, the Federal Aviation Administration and NASA in the US are working closely with industry on safety standards and airspace integration concepts. The European Union Aviation Safety Agency is also active in establishing regulations. Individual nations have started to implement enabling policies too - Singapore recently established Asia's first regulatory framework and testing facilities specifically for autonomous air vehicles. If key challenges around certification, training, airspace integration and charging infrastructure can be successfully addressed, advanced aerial mobility has great potential to multiply cities' connectivity in new dimensions. Electric aircraft could eventually offer zero-emissions point-to-point flights everywhere from busy downtown financial districts up to nearby suburbs or even between adjacent cities. Autonomous cargo drones could transform intra-urban and business-to-business logistics. Both would help alleviate pressure on overused road networks. With focused cooperation between innovators and policymakers, the future of urban transportation may well be found in citizens taking to the skies.
