Following is a question by the Hon Chan Siu-hung and a reply by the Secretary for Transport and Logistics, Ms Mable Chan, in the Legislative Council today (July 16):

Question:

     The National Development and Reform Commission has earlier on emphasised the expansion of application scenarios for low-altitude economic activities in a well-classified and orderly manner, on the premise that risks be stringently controlled and safety be ensured. On promoting the safe and healthy development of the low-altitude economy industries, will the Government inform this Council:

(1) given that the establishment of a "visible and manageable" fully digitalised low-altitude airspace management system is a key element in managing and controlling the safe and orderly flights of a wide range of high-traffic-density and high-frequency aircrafts in the airspace, whether the Government has a timetable for the establishment of the system concerned; if so, of the details; if not, the reasons for that;

(2) as there are views pointing out that the data derived from the low-‍altitude economy have high economic values, and data security will have a direct impact on the efficiency and safety of the use of airspace, whether the Government will study the establishment of a data security system to promote standardised management and the safe and efficient use of low-altitude data, as well as to facilitate the transformation of data value; and

(3) whether it will, by drawing reference from the development experience in the Mainland and other places around the world, conduct quantitative analysis on the economic benefits brought about by low-altitude infrastructure and the related industries, and formulate a plan for development of such facilities through a public-‍private partnership approach, so as to attract more infrastructure investments; if so, of the details; if not, the reasons for that?

Reply:

President,

     Low-altitude economy (LAE) is a national strategic emerging industry and an example of developing new quality productive forces. For LAE to "fly far", it must first "fly steady". Therefore, safety is undoubtedly a prerequisite for LAE development.

     In consultation with the Innovation, Technology and Industry Bureau, the Development Bureau (DEVB) and the Civil Aviation Department, the reply to the Hon Chan's question is as follows:

(1) Robust low-altitude infrastructure is a critical element in ensuring the safe and orderly operation of low-altitude flying activities. Given Hong Kong's unique urban landscape characterised by dense high-rise buildings and varied terrain, the low-altitude operating environment is particularly challenging. The establishment of digitalised low-altitude infrastructure, particularly the Smart Low-altitude Traffic Management System, coupled with the formulation of a comprehensive data policy, is essential to ensuring the safe, efficient, and sustainable development of LAE.

     Building on the experience gathered from the Regulatory Sandbox (Sandbox) pilot projects, the Government will formulate the conceptual model and technical specifications for a Smart Low-altitude Traffic Management System. To implement these plans, the Government will commence a technical study within this year, drawing on the Mainland and international advanced practices to ensure that the technical parameters of low-altitude infrastructure, including the Smart Low-altitude Traffic Management System, are compatible with regional and international regulatory standards.

(2) The development of LAE will generate significant volumes of data resources such as flight data collected during unmanned aircraft operations, the secure and efficient utilisation of which will directly affect the industry's development potential. In respect of data management and data security of government systems, the relevant bureaux and departments (B/Ds) at present must comply with the Government IT Security Policy and Guidelines, which require for example encrypting data both in transit and at rest, prohibiting the storage of sensitive and personal data on public cloud platforms, and conducting regular security risk assessments and audits as well as privacy impact assessments for B/Ds' information systems. These measures aim to ensure that data are kept secure and reliable and meet all applicable legislative and regulatory requirements, including requirements on privacy protection of personal data.

     Given the above and in accordance with the open data policy of the Government, data collected by LAE projects can, depending on the circumstances, be made available to the public via the existing digital infrastructures such as the Open Data Portal and the Common Spatial Data Infrastructure Portal (CSDI), thereby fostering more LAE-related applications and industry development. In fact, a considerable amount of data beneficial to the development of the LAE, e.g. maps, aerial photographs, 3D spatial data, building data, traffic data and weather data, etc, has already been shared with the industry through the aforementioned government data platforms, facilitating various sectors to explore more application scenarios of low-altitude flying activities and unlock the full potential of the data.

     Furthermore, the DEVB, the Lands Department and relevant departments will jointly explore the feasibility of sharing LAE-related data through a unified platform, and build a three-dimensional information hub dedicated to low-altitude flying activities as a pilot project to conduct a proof-of-concept for sharing data collected by unmanned aircraft. This hub will make reference to the data sharing model of the Mainland and closely connect with the CSDI developed by the DEVB to unify and integrate data from different sources, and be equipped with relevant data dashboards to enable thematic information sharing between the Government and relevant stakeholders relating to low-altitude flying activities.

(3) The development of low-altitude infrastructure is a forward-looking systematic project. Through government guidance and cross-sector collaboration, it can accelerate industrial upgrading and drive the robust growth of LAE. In addition to the investment of government resources, we believe that private market participation is also an indispensable driving force, particularly in areas such as the construction of takeoff/landing sites and the planning of mobile radio communications network. Drawing reference from the experiences and various models adopted in the Mainland and other regions, we will proceed step-by-step in taking forward the relevant work on the development of LAE infrastructure. Throughout this process, the Government will, on the premises of safeguarding aviation and public safety, explore various operational models conducive to the development of LAE to foster long-term economic benefits.

     At present, the Government is testing different low-altitude flying application scenarios, technical and site requirements, and cross-departmental regulatory co-ordination through the Sandbox pilot projects. The aims are to gather data, accumulate experience, and examine the infrastructure, safety standards, and legislative and regulatory framework necessary for LAE development, thereby providing trial experience and evidence-based foundation of various application scenarios for the planning of LAE development, including the feasible models for the construction of LAE infrastructure. Our vision is that while the Government creates a favourable ecosystem through top-level design, standard-setting, and institutional innovation, the private sector will drive industrial advancement through technological breakthrough and business model innovation. This public-private collaboration model will pave the way for the sustainable development of LAE in Hong Kong.

     Thank you, President.
