This paper presents a comprehensive framework for the integration of low-altitude economic activities, specifically focusing on drone delivery services, within the urban landscape of Hong Kong. As the city grapples with urban congestion and the limitations of traditional transportation systems, the potential of Small Unmanned Aircraft Systems (SUAs) emerges as a transformative solution to enhance logistics efficiency and stimulate economic growth. Through a rigorous methodology that includes a review of existing regulations, expert interviews, and stakeholder engagement, the study identifies critical gaps in the regulatory framework governing low-altitude operations. The proposed design scheme outlines a strategic airspace classification system, dividing the city into manageable zones based on building density and height, thereby facilitating safe and efficient drone operations. Additionally, the paper explores the implications of drone operations on the urban environment and user experience in Hong Kong, examining how these activities can reshape public spaces and enhance accessibility. By advocating for a collaborative approach among urban planners & designers, civil aviation authorities, and technology developers, this research aims to establish guidelines that harmonize drone operations with urban design principles, ultimately contributing to a more interconnected, efficient, and sustainable urban environment in Hong Kong.
