This white paper by EHang explores Urban Air Mobility (UAM) as a transformative solution for urban transportation challenges, emphasizing safety, autonomy, and centralized command-and-control systems. It outlines the technological, regulatory, and infrastructural frameworks needed to realize UAM’s potential, positioning it as a sustainable alternative to traditional ground and air transport
Core UAM Concept
Urban Air Mobility (UAM) redefines urban transportation through autonomous aerial vehicles (AAVs) operating on pre-defined routes managed by centralized platforms. Key innovations include:
  • Safety: Redundant power systems, obstacle avoidance, and autonomous operations eliminate human error.
  • Efficiency: Point-to-point air routes reduce travel time (e.g., a 40-minute road trip shortened to 5 minutes via EHang’s 2019 pilot route in Zhejiang, China).
  • Sustainability: Electric propulsion ensures zero emissions, addressing urban pollution.
Key Components
  1. AAVs: EHang’s EH216 (2-seater) and EH116 models feature 8–16 rotors, autonomous navigation, and a 20–30 km range.
  2. Command-and-Control Platform: Centralized systems enable real-time fleet management, route optimization, and integration with smart-city infrastructure.
  3. Vertiports (Base Points): Modular landing pads with charging stations form the UAM network’s backbone.
Applications
  • Tourism: Aerial sightseeing in remote or congested areas (e.g., China’s 2,500+ AAAA-class scenic spots)
  • Emergency Services: Air ambulances for rapid medical response and aerial firefighting in high-rise buildings.
  • Industrial Logistics: Offshore oil rig support and wind farm maintenance.
Market Potential
  • Projected to reach $1.5 trillion by 2040 (Morgan Stanley).
  • EHang has already commercialized AAVs, delivering 38 units by 2019 and securing CAAC certification for passenger flights.
Regulatory and Technological Challenges
  • Regulations: Collaboration with global bodies (FAA, EASA, CAAC) to establish airspace management and safety protocols.
  • Technology: Advances in battery efficiency (e.g., reducing costs by 1% boosts profits by 3%) and 5G connectivity for real-time data transmission
