Low-altitude Economy Regulatory Sandbox (“Sandbox”)

The Sandbox aims to enable industry stakeholders to test and conduct trials on some project concepts within pre-defined air routes and in a controlled and safe manner. The objectives are to -

1. support the Government in developing policies and regulatory guidelines that better embrace the latest technologies as well as the needs of the industry while ensuring public and aviation safety;
2. conduct trials relevant to airspace management, flight operations, infrastructure/facilities (including storage/carriage and ground supporting facilities), and emergency response required to support the safe and efficient operations of unmanned aircraft;
3. adopt a risk-based approach to conduct tests and trials at various locations to collect data against various parameters such that safe and reliable flights can be ensured within the parameters, including:
   • environmental factors (such as temperature, visibility, rain/humidity, wind speed, etc.);
   • date of the week/time of the day;
   • unmanned aircraft’s weight and payload;
   • flying altitude and speed;
   • strength and stability of the signals for Global Navigation Satellite System with consideration on ionospheric disturbance, and communication/surveillance network in the unique environment of Hong Kong with surrounding terrain and high-rise buildings, including remote, sparsely populated, over-water and cross-boundary areas, etc.;
   • response to various emergency situations with multiple layers of risk mitigating measures; and
   • simultaneous operations of multiple unmanned aircraft;
4. enable the Government to collect data to validate that the applications are viable and can meet the relevant safety, stability, reliability and resilience requirements;
5. demonstrate safe segregation from aircraft, helicopters, other airspace users, people, vehicles, vessels and building structures;
6. showcase applications of technologies relevant to low-altitude economy (“LAE”);
7. for cross-boundary applications, validate procedures and liaison between relevant authorities in the Mainland and Hong Kong (including but not limited to Customs, Immigration and Quarantine (“CIQ”)) arrangements and other relevant requirements; and
8. enable participants to gather, under a controlled environment, data and user feedback so that they can make refinements to their LAE applications and projects, thereby expediting the launch of new LAE products or services, and reducing the development and pre-launch costs.

• Working Group on Developing Low-altitude Economy holds first meeting (November 12, 2024)
• Regulatory sandbox pilot projects officially launched to foster low-altitude economy and innovative industry development (March 20, 2025)

Q.1 Can the same applicant/organisation submit more than one application? Or can the same applicant/organisation submit more than one application in collaboration with different organisations?
A.1 Yes. The same applicant/organisation may apply for multiple trials/ routes, including collaboration with different organisations, to explore various project concepts and innovative ideas.

Q.2 The venue partners of the Sandbox are the Hong Kong Science and Technology Parks Cooperation and the Hong Kong Cyberport Management Company Limited. Does it mean that the pilot projects can only be conducted in the above two places? Can we apply for implementing the pilot projects in other locations?
A.2 The Government has appointed the Hong Kong Science and Technology Parks Corporation and the Hong Kong Cyberport Management Company Limited as venue partners, with the objective of streamline the applicants' efforts in venue arrangements. That said, applicants may also propose to conduct trials at other locations. When evaluating the application, the Working Group will consider the feasibility and readiness of the proposed site. Please refer to Part 5 of AC-013 regarding the factors for consideration in respect of operating area and/or flight path.
AC-013 can be downloaded from https://www.cad.gov.hk/documents/AC-013.pdf.

Q.3 While the first phase of the Sandbox will mainly cover drone deliveries, can we submit applications for non-goods-carrying projects?
A.3 Yes. The purpose of the Sandbox is to enable the industry to test some project concepts in a controlled and safe manner within designated flight paths, with a view to progressively expanding and enriching the scope of low-altitude flying applications. Hence, apart from drone deliveries, applicants may also submit applications for non-goods-carrying projects (e.g. building maintenance /repair) for the Working Group's evaluation and prioritisation.

Q.4 What factors will the Working Group take into consideration when evaluating applications for various pilot projects? Is there any marking mechanism?
A4. When evaluating each eligible application, the Working Group will take into account a basket of factors including, but not limited to, the scope of application, whether it is innovative and make use of local research and development (R&D) technologies, whether it can help enhance local experience in different areas for the development of the low-altitude economy (e.g. air route network design, infrastructure requirements, emergency response, regulatory regime, etc.), as well as the applicant's skills and experience, etc.

Q.5 Will the Government provide financial assistance to the selected Sandbox pilot projects?
A5. The Government has been supporting research and development (R&D) in various technology areas through the Innovation and Technology Fund (ITF), including the funding schemes under the ITF to support local universities, R&D centres and enterprises to conduct R&D in areas including electronics, data transfer and processing related to LAE.
The General Conditions of the Sandbox states that any costs in preparing the applications and conducting the trials will be borne by the Sandbox pilot projects applicants through their self-arranged financial and / or other funding sources.

The government received a total of 72 applications for the "Regulatory Sandbox" pilot projects submitted by applicants. After evaluation by the Working Group on Developing Low-altitude Economy, 38 projects will be implemented. The applying institutions include mainland and local organizations, university research institutions, public institutions, commercial enterprises, universities/research institutions, public utility organizations, and government departments. The project contents cover various fields and application scenarios such as emergency and rescue, drone delivery, inspection and safety maintenance, surveillance and low-altitude infrastructure. Please visit the following page for the relevant list.

As of 31 October 2025, twenty eight Regulatory Sandbox pilot projects have been implemented. For the project details, please refer to the attached list.
