5. About Aircraft Noise Pollution In Hong Kong
• With a daily average of approximately 910 flight movements at the Hong Kong
International Airport, aircraft noise is a particular environmental concern. That noise and
its affect on the community is being minimised with measures including:
• The preferential use of runways and flight paths at night to avoid overflying densely
populated areas as much as possible.
• Noise abatement departure and approach procedures.
• The prohibition of noisy aircraft from operating at the Airport.
• Aircraft noise and flight tracks are monitored around the clock by the Aircraft Noise
and Flight Track Monitoring System, which comprises 16 noise monitoring terminals
installed at various areas under or near landing and take-off flight paths. (From HKEPD)
