Two legislative amendments on low-altitude economy development will come into effect tomorrow.

The two amendments - The Small Unmanned Aircraft (Amendment) Order 2025 and the Air Navigation (Hong Kong) Order 1995 (Amendment) Order 2025 - are aimed at facilitating the development of a low-altitude economy.

The amendments to the Small Unmanned Aircraft (SUA) Order serve to extend the existing regulatory regime to cover SUA weighing over 25kg but not exceeding 150kg.

Relevant guidance documents including the updated Safety Requirements Document and Advisory Circulars will be available online from tomorrow.

Meanwhile, the amendments to the Air Navigation (Hong Kong) Order 1995 serve to facilitate the trials of various unconventional aircraft in Hong Kong.

New articles are added to empower the Chief Executive to permit the trials of unconventional aircraft under specified conditions.

Practical guidance in respect of the trials of unconventional aircraft will be published online tomorrow.
