The 8th World UAV Conference 2024 recently held in Shenzhen showcased a flying saucer-shaped manned aircraft, drawing significant public interest and curiosity. This event spotlighted the burgeoning low-altitude economy, sparking questions about the practicality and timeline of innovations like “flying to work.”
Understanding the Low-Altitude Economy and eVTOLs
Low-Altitude Economy
The low-altitude economy encompasses activities conducted below 3,000 meters using manned or unmanned aerial vehicles, significantly impacting various sectors. This new economic sphere is driven by advancements in aerospace technology and aims to integrate multiple applications such as logistics, transportation, and surveillance. The growth of this sector promises to revolutionize how goods and people move within urban environments, enhancing efficiency and reducing congestion on traditional roadways.

eVTOLs
Electric Vertical Take-Off and Landing (eVTOL) aircraft are a critical component of the low-altitude economy. They promise to revolutionize urban commuting and transportation by enabling vertical take-offs and landings in compact spaces, eliminating the need for traditional runways. eVTOLs can be broadly categorized into cargo and passenger types, with passenger eVTOLs being akin to small aircraft in terms of functionality. Industry experts predict large-scale commercialization of passenger eVTOLs by 2027, contingent on successful airworthiness certification and public acceptance.

Progress in Certification
Achieving airworthiness certification for eVTOLs is a complex process, similar to that of traditional aircraft, requiring three key certificates: Type Certificate (TC), Airworthiness Certificate (AC), and Production Certificate (PC). The TC is particularly critical and challenging due to the lack of mature global standards for these innovative vehicles.
China’s Milestones
China has made notable progress in this arena. The Civil Aviation Administration of China (CAAC) recently issued the world’s first eVTOL Type Certificate to EHang’s EH216-S, signaling a significant milestone in the global eVTOL industry. This certification process, which took just over two years, underscores China’s commitment to leading in this emerging field.
Other models, such as Shanghai Fengfei’s V2000CG, are also advancing through certification. This model is the first globally to pass type certification for a ton-class eVTOL, indicating rapid advancements and a competitive edge. These certifications are essential for ensuring safety and reliability, paving the way for broader adoption and commercialization.
Policy Support and Market Potential
Government Initiatives
Government policies at both national and local levels are pivotal in accelerating the development of the low-altitude economy. In November 2023, the CAAC issued the “Regulations on the Administration of the People’s Republic of China Airspace (Draft for Comments),” aiming to simplify approval procedures for low-altitude flying activities and provide more operational space.
Additionally, the “Green Aviation Manufacturing Development Outline (2023-2025)” issued by the Ministry of Industry and Information Technology, alongside other departments, sets a target for eVTOLs to achieve pilot operations by 2025. These policies are designed to integrate eVTOLs into the comprehensive three-dimensional transportation network, highlighting the government’s support and recognition of the sector’s potential.
Regional Efforts
Regions like Guangdong and Anhui are actively promoting eVTOLs for urban air mobility, exploring new business forms such as air commuting, business travel, and air shuttles. Cities like Shenzhen, Suzhou, and others are also developing action plans to integrate eVTOLs into their public transportation networks. For instance, Shenzhen’s Bao’an District aims to advance the maiden flight and first test of manned air transportation, actively applying for the first batch of national smart air transportation pilot districts.
Market Projections
The market potential for eVTOLs in China is immense. By 2030, the potential market capacity for new general aviation travel could exceed 300,000 units, driven by urban commuting and short-distance intercity travel. This underscores the significant economic opportunities that lie ahead. Data from the 8th World UAV Conference 2024 suggests that China will become the largest urban air transportation market globally, potentially accounting for 20% to 25% of the global eVTOL market by 2040.
Challenges and Infrastructure Needs
Despite the progress in certification and policy support, several challenges must be addressed for large-scale commercial operations of eVTOLs.
Infrastructure Deficits
One of the primary challenges is the lack of infrastructure, particularly large take-off and landing sites capable of handling multiple eVTOLs simultaneously. Currently, such facilities are almost non-existent in China, creating a bottleneck for the industry’s growth. Developing these infrastructure elements is critical for the successful deployment of eVTOLs in urban environments.
Battery Technology
Battery performance is another critical barrier. eVTOLs require significantly more power for vertical take-off compared to ground travel, necessitating advanced batteries with higher energy density. Current mainstream lithium batteries are inadequate, and significant technological breakthroughs are needed to make eVTOLs viable for large-scale operations. The energy density of batteries must reach a level where they can compete with traditional internal combustion engines in terms of efficiency and performance.
Management Systems
Effective management systems are crucial for the safe and efficient operation of eVTOLs. Traditional airspace management relies on voice communication between towers and pilots. However, managing eVTOLs will require new technologies, including AI, big data, and advanced communication systems. Establishing a robust communication navigation surveillance system is essential for the industry’s development. This system would ensure real-time monitoring and management of eVTOL traffic, preventing potential collisions and ensuring smooth operations.
Regulatory Coordination
The regulatory landscape for the low-altitude economy is complex, involving multiple management departments. There is a need for centralized coordination, similar to the role of the Central Cyberspace Administration, to streamline regulatory processes and ensure efficient management. This would help in addressing the multifaceted challenges of integrating eVTOLs into existing airspace and urban infrastructure.
Economic and Environmental Considerations
eVTOLs must also prove their economic viability. For large-scale adoption, eVTOLs need to demonstrate cost-effectiveness, including lower acquisition costs, high flight speeds, and high load ratios to improve operational efficiency. Moreover, environmental considerations such as noise pollution and carbon footprint must be addressed to gain public acceptance and regulatory approval.
Conclusion
With increasing policy support, technological advancements, and growing market potential, the eVTOL industry holds significant promise for transforming urban transportation and driving the low-altitude economy. However, addressing infrastructure, technological, and regulatory challenges remains essential for realizing the full potential of this innovative sector. The future of urban air mobility is on the horizon, and with concerted efforts, “flying to work” could soon become a reality.
The path forward involves a collaborative effort between government bodies, private enterprises, and the public to build a sustainable and efficient low-altitude economy. As the industry continues to evolve, ongoing research and development, coupled with robust policy frameworks, will be crucial in overcoming current limitations and unlocking new opportunities. The dawn of eVTOLs signifies a bold step towards a more connected and dynamic urban landscape, heralding a new era in transportation and economic growth.
