In the process of gradually developing towards large-capacity integrated flights featuring "heterogeneity, high density, high frequency, and high complexity", major cities are still faced with five major challenges: "difficulty in flight management", "difficulty in multi-party coordination", "difficulty in ensuring safety", "difficulty in resource sharing", and "difficulty in forming a business closed loop". Aiming at the flight demands of "high complexity, large scale, and ultra-high safety", a new generation of urban low-altitude digital management and service system has been created, providing full-chain engine capabilities such as low-altitude airspace planning, air route design, operation supervision, facility supervision, accident prediction and analysis, etc., and supporting a new mode of performance-based low-altitude intelligent control and management.
