Civil Aviation Department

What Civil Aviation Department does

Civil Aviation Department (CAD) is a department of the Hong Kong Special Administrative Region Government, established in 1946, that serves as the territory's civil aviation regulatory authority. It provides air traffic services across the 276,000 km² Hong Kong Flight Information Region (FIR) extending over the South China Sea, and is responsible for licensing and certification of aviation personnel and operators, airport and aerodrome standards, airworthiness regulation, air services facilitation, and aircraft accident and incident investigation. The department is led by Director-General of Civil Aviation Victor Liu Chi-yung, JP, with a Deputy Director-General and departmental secretary, and operates two principal sites at Hong Kong International Airport — the headquarters at 1 Tung Fai Road and a backup ATC complex at 25 Chung Cheung Road.

Core technical assets include CNS/ATM (Communications, Navigation, Surveillance/Air Traffic Management) systems implemented in line with the ICAO Global Air Navigation Plan, air traffic control surveillance simulators for training, an Advanced Surface Movement Guidance and Control System (A-SMGCS) for low-visibility and night operations, and an Aeronautical Information Management Centre publishing AIP, AIC, and NOTAM. Digital service platforms include the Personnel Licensing Information System (PLIS, mandatory from 2 July 2024), the Electronic Portal for Small Unmanned Aircraft (eSUA, launched 2022), the CADSTAT E-filing System, the Flight Application e-Filing System, and the Hong Kong Schedule Coordination Office (HKSCO). CAD also participates in the Low-altitude Economy Regulatory Sandbox and hosts the Asia Pacific Region Innovation & Capacity Building Symposium.

CAD does not generate commercial revenue. It collects government fees for permits, licenses, and certificates (e.g., Air Operator's Certificates, Certificates of Airworthiness, personnel licensing), but explicitly charges no fees for applications to operate air services to and from Hong Kong. As a government entity, it is funded through HKSAR Government appropriations and is not equity-backed. International cooperation is anchored in bilateral arrangements with the Civil Aviation Administration of China (CAAC) and the Civil Aviation Authority of Macao — including joint maintenance management (2021), C919/ARJ21 aircraft evaluation support (2018), and a renewed tripartite Cooperation Arrangement (30 April 2026) — plus working arrangements with EASA (2011), the Civil Aviation Authority of Singapore (2008), and active ICAO working group participation.

Core offering

Civil Aviation Department (CAD) is a Hong Kong government department that regulates civil aviation, provides air traffic services for the 276,000 km² Hong Kong Flight Information Region, licenses aviation personnel and aircraft, sets aerodrome safety and security standards, and manages air traffic engineering infrastructure. It also operates digital service platforms including the Personnel Licensing Information System (PLIS) and the Electronic Portal for Small Unmanned Aircraft (eSUA), and issues aeronautical information publications for the international aviation community.

Product overview

Civil Aviation Department is a Hong Kong government department providing aviation regulatory services, not a commercial product company. The department operates multiple digital service platforms including the Personnel Licensing Information System (PLIS) for pilot and engineer licensing, the Electronic Portal for Small Unmanned Aircraft (eSUA) for drone registration and compliance, the CADSTAT E-filing System for air traffic statistics, and flight application e-filing for operator permits. Core services span air traffic management across the 276,000 km² Hong Kong Flight Information Region, airport standards regulation, flight standards and airworthiness certification, air traffic engineering, and aviation education. The department also supports the low-altitude economy through regulatory sandbox initiatives.

Direct peers

• Civil Aviation Authority of Singapore (CAAS): CAAS is the closest geographic and functional peer to CAD — a small-city-state civil aviation regulator and air navigation service provider operating similar ATC, licensing, airport standards, and emerging UAS/UAM regulatory functions. Both serve as regional benchmarks for advanced airspace management in Asia.
• DFS Deutsche Flugsicherung: DFS is Germany's air navigation service provider operating CNS/ATM and ATC across a large, complex European FIR — directly comparable to CAD in technology scope (radar, navigation aids, training simulators) and operational performance benchmarks.
• NAV CANADA: NAV CANADA is a non-government ANSP providing ATC and CNS/ATM services over a very large FIR — comparable to CAD in operating a sovereign airspace footprint under a quasi-governmental service-provider structure with similar technology and training mandates.
• NATS (UK Air Navigation Service Provider): NATS provides air traffic control services across UK airspace and at multiple airports under a public-interest governance model — directly comparable to CAD's air traffic management and engineering services functions, and operates CNS/ATM infrastructure at similar scale and reliability standards.
• Airservices Australia: Airservices Australia provides ATC and CNS/ATM over a large FIR under a government-owned corporation model — comparable to CAD in managing an outsized airspace area, advanced surface movement systems, and ICAO-aligned operational standards.
• Civil Aviation Authority of New Zealand (CAA NZ): CAA NZ is a small-jurisdiction civil aviation regulator performing ATC, licensing, and airworthiness functions over a large maritime FIR — directly analogous to CAD's operational profile of governing Hong Kong's 276,000 km² airspace from a compact land base.

Broad incumbents

• Federal Aviation Administration (FAA): The FAA is the largest and most influential civil aviation regulator globally, performing the same licensing, airworthiness, ATC, and airport standards functions as CAD but at continental US scale. It is the implicit benchmark for ICAO-aligned frameworks CAD adopts.
• European Union Aviation Safety Agency (EASA): EASA is the EU's civil aviation safety regulator with which CAD has a working arrangement — comparable scope in airworthiness, flight crew licensing, and aerodrome standards, but operating as a supranational body rather than a national authority.
• Civil Aviation Administration of China (CAAC): CAAC is the mainland China civil aviation regulator and CAD's closest strategic partner — operates the same regulatory and ATC functions but at vastly larger scale; CAD's cooperation arrangements (C919 evaluation, joint maintenance, GBA airspace) make it the most directly relevant counterpart.

Others

• Airport Authority Hong Kong (AAHK): AAHK operates HKIA itself, while CAD regulates and provides ATC at that airport — they are tightly coupled operational partners on the Three-Runway System and capacity reviews but are functionally distinct (operator vs. regulator/ANSP), making AAHK an adjacent ecosystem participant rather than a true peer.
