There are 4 major external problems and constraints in HKSAR’s airspace management
- HKFIR is within the Pearl River Delta (PRD) region of which airspace is relatively small – this increases the airspace complexity. For example, flow control from Mainland ATC is not unusual – it can be a result of weather, traffic loads, and military activities etc.
- VHHH is proximate to VMMC – the HK ATC need also providing ATS for en-route traffic – this increases the ATC workloads, we also need to share the slots with Macau under limited ATS routes.
- HKFIR adopts different cruising level system from the Mainland China (e.g HKFIR uses feet as altitude unit and the Mainland China uses meter)
- HKFIR has different separation standards from Mainland China – this makes impact on area navigation procedures
