Airport Authority Hong Kong (AAHK), is finalising a development plan for construction of a third runway at Hong Kong International Airport in China.

Hong Kong Civil Aviation Department director-general Norman Lo said the two runways at the airport will reach full handling capacity by the end of 2020 if aircraft movements continue to grow at a compound annual growth rate of around 5%.

The airport has previously built new facilities to manage the increasing demand, including a new terminal and a new air traffic control centre, however, the runway capacity remains a constraint, during peak hours.

The airport will be able to handle a maximum of 68 aircraft movements including take-offs and landings per hour by 2015, following the construction of the runway, according to The Wall Street Journal.

AAHK will unveil the plan for public consultation to understand the potential economic and environmental impact of constructing a third runway.
