Hong Kong Flight Rules | HKCAD & Hong Kong FIR VHHK Requirements

Do You Need a Hong Kong Overflight Permit?

Hong Kong should not be presented as having one identical overflight-permit rule for every operation. HKCAD's current public flight-application guidance specifically requires permits or prior clearance for charter and private non-revenue flights to and from Hong Kong, generally with applications at least 3 working days before operation. For pure transit through Hong Kong FIR, operators should verify the current Hong Kong AIP, ATC routing and any operation-specific authorization rather than relying on a blanket 24–72-hour permit claim.

Hong Kong Permit and Flight Support Requirements

For Hong Kong overflight, landing, route approval, slot or trip support coordination, operators should normally provide the following details:

• Aircraft registration and aircraft type
• Operator name and full contact details
• Complete flight schedule with UTC date and time
• Departure airport and destination airport
• Full route including Hong Kong FIR entry and exit points
• ATC route and call sign / flight number
• Purpose of flight and type of operation
• Lead passenger details where applicable
• Airport slot, handling and fuel requirements for VHHH / HKG operations

Required Documents for Hong Kong Coordination

• Certificate of Registration (COR)
• Certificate of Airworthiness (COA)
• Valid aircraft insurance certificate (COI)
• Noise certificate (CON)
• Air Operator Certificate (AOC) for commercial operators
• Crew and passenger details when required
• Dangerous goods declaration if applicable
• Special approval or mission documents for ambulance, humanitarian, ferry or state-related flights

Hong Kong Flight Permission / Coordination Lead Time

For charter and private non-revenue flights to or from Hong Kong, HKCAD currently states that applications should generally be submitted at least 3 working days before the anticipated arrival or departure. Non-frequent or new charter operators are advised to apply at least 2 weeks in advance. Pure FIR transit should be checked against current AIP and ATC requirements; do not present 24–72 hours as a universal overflight lead time.

Hong Kong FIR Information

Hong Kong airspace is commonly planned through Hong Kong FIR (VHHK). Operators should verify FIR boundary estimates, ATS routing, entry and exit points and applicable flight plan addressing before operation.

The primary airport is Hong Kong International Airport (VHHH/HKG) at Chek Lap Kok, serving passenger, cargo, business aviation and technical stop operations.

Operators may also coordinate full flight support and ground handling services including slot coordination, routing validation and fuel arrangements for Hong Kong operations.

Hong Kong FIR Entry and Exit Points

The following entry and exit points were provided in the original Hong Kong permit page for route planning. Operators should verify routing against the latest approved ATS route structure before filing the flight plan.

Hong Kong Flight Plan Submission

According to the supplied Hong Kong AIP content, aircraft intending to conduct an IFR flight within Hong Kong FIR should file a flight plan. Authorized operators may submit a CAD-approved flight notification form for certain local VFR flights.

For flights departing Hong Kong International Airport, flight plans may be filed by Private Communication Network (PCN), AFTN for scheduled operations, or by Flight Plan Form DCA6a. Flight plan data should be accurate and in the required format because the Hong Kong Flight Data Processing System is automated and may reject incorrectly formatted data.

Hong Kong Flight Plan Timing

Airline operators can file a flight plan up to 5 days / 120 hours prior to EOBT. Except where necessary for operational or technical reasons, aircraft operating to or from Hong Kong should normally submit a flight plan at least 3 hours before EOBT and in no case later than 60 minutes prior to EOBT.

In the event of a delay of 15 minutes beyond the last transmitted EOBT, the flight plan should be amended with a DLA message, or a new flight plan should be submitted and the old one cancelled where applicable.

Hong Kong Flight Plan Item 18 Notes

Aircraft planning to enter or transit Hong Kong FIR should include the required Item 18 information in the flight plan, including the date of flight, national registration when different from Item 7, and accumulated estimated elapsed time to Hong Kong FIR in the form EET/VHHK followed by a four-figure group for hours and minutes.

Only specific indicators should be used in Item 18, and the required sequence of indicators should be followed. Free text should not be used for STS/ unless permitted by applicable ICAO procedures.

Hong Kong ATS Message Addressing

Flight movement messages relating to traffic into or via Hong Kong FIR should be addressed correctly to support relay and delivery.

PCN, AFTN and Flight Plan Form Notes

Airline operators may use the Private Communication Network service to submit flight plans to the Aeronautical Information Management Centre for departures from Hong Kong International Airport. PCN flight plan forms mimic ICAO flight plan format and are checked for syntax, aircraft type, location indicators, route format, AFTN addresses and Item 18 ordering.

AFTN filing is applicable to scheduled flight operations. For flight plan form submission, the DCA6a form should be completed clearly and submitted to AIMC according to the specified procedure. The ultimate responsibility for compiling an accurate flight plan rests with pilots and/or airline operators.

Repetitive Flight Plan and RVSM Notes

The supplied Hong Kong AIP content notes that a repetitive flight plan system is available for specified scheduled routes. When filing a repetitive flight plan, operators should include RVSM approval status information in the appropriate field, using EQPT/W for RVSM-approved flights or STS/NONRVSM where applicable.

Hong Kong International Airport Support

Permit2Fly can coordinate airport slots, landing support, handling, parking and fuel at Hong Kong International Airport depending on aircraft type, schedule, operation category and supplier availability.

• Hong Kong International Airport (VHHH / HKG)
• Airport slot and parking coordination
• Ground handling and supervisory support
• Jet A-1 fuel uplift coordination
• Crew, passenger and cargo support
• Short-notice operational follow-up

Overflight Charges, Airport Slots and Navigation Fees

Hong Kong overflight, navigation, airport and handling charges may depend on the type of aircraft operation, route, aircraft weight category, airport slot requirement and services requested. Where landing is involved, operators should also consider parking, ground handling, fuel uplift, supervision, passenger handling, cargo handling and any additional airport or supplier charges.

Airport slots and parking availability can be critical at Hong Kong International Airport, especially during peak operating periods and cargo hub activity.

Operational Restrictions and Special Approvals

Certain flight categories may require additional review or longer coordination time. Operators should provide complete information early when the flight involves special cargo, state-related movement, dangerous goods, ambulance operation or unusual routing.

• Military, diplomatic or state flights
• Dangerous goods or special cargo flights
• Ambulance, medevac and humanitarian missions
• Survey, inspection, ferry or delivery flights
• Flights with restricted cargo or unusual routing
• Flights requiring landing permit, airport slot, passenger handling or cargo handling

Landing Permit, Handling and Fuel Support

Our flight operations support can also assist with airport coordination, service confirmation, schedule revision, supplier follow-up and communication with the operator until flight completion.

About Hong Kong

Hong Kong is one of Asia’s most important international aviation hubs, with Hong Kong International Airport serving major passenger, cargo, business aviation and technical stop operations.

Due to busy regional traffic flows, slot management and high-density airspace around Hong Kong FIR, advance flight plan, route, slot and airport coordination helps reduce operational delays and service disruptions.
