The Civil Aviation Department (CAD) of Hong Kong has in place a series of measures to manage and control aircraft noise.

The CAD monitors aircraft’s adherence to defined flight paths, and continuously monitors noise levels and answers enquiries and complaints from the public relating to aircraft noise. It has implemented a number of noise controlling measures, including:

  • Avoiding aircraft overflights in densely populated urban areas;
  • Using noise abatement departure procedures for North East departures (aircraft must reach higher altitudes in a shorter distance);
  • Requiring South West approaches over water whenever possible; and
  • Requiring continuous descent approaches for flights arriving from the North East.

Full details on the CAD's aircraft noise management efforts are available on the CAD's website.
