Operations of Unmanned Aircraft Systems (UAS)


Hong Kong is a densely populated city with busy air traffic (both helicopter and airliner). Any person who operates Unmanned Aircraft Systems (UAS) must stay vigilant and follow the related safety requirements to avoid causing damage to property, injuries and even fatalities.

The Air Navigation (Hong Kong) Order 1995 (Chapter 448C of the Laws of Hong Kong) Article 48 stipulates that a person shall not recklessly or negligently cause or permit an aircraft (including drone/UAS) to endanger any person or property. Offenders are liable to prosecution and upon conviction to a fine and up to two years' imprisonment.

For operations of Unmanned Aircraft Systems (UAS) weighing not more than 7 kg (without its fuel) for non-hire or reward purpose (e.g. recreational operations), no application to CAD is required. However, the operators still have to comply with relevant regulations and CAD’s guidelines for safe UAS operations.
