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.
