There are possible drawbacks. Development costs are a concern: although the proposal would increase the number of direct jobs associated with HKIA to 150,000 by 2030 and generate an ENPV of HK$912 billion (in 2009 dollars), the estimated cost is approximately $86.2 billion (2010) Hong Kong Dollars, or HK$141.5 billion (at money-of-the-day prices). There are also environmental and local noise pollution concerns. On 20 March 2012, the Hong Kong Government adopted this option as the official expansion plan. The third runway, with its own dedicated passenger concourse, is currently being built parallel to the current two runways on reclaimed land directly north of the existing airport island. It is expected to open by the end of 2024. The airport is operated by the Airport Authority Hong Kong, a statutory body wholly owned by the Government of Hong Kong Special Administrative Region. The airport has two parallel runways, both of which are in length and wide. The south runway has a Category II Precision Approach, while the north runway has the higher Category IIIA rating, which allows pilots to land in only visibility. The two runways have a capacity of over 60 aircraft movements an hour. The Airport is upgrading ATC and runways so that they can handle 68 movements per hour. Normally, the north runway (07L/25R) is used for landing passenger planes. The south runway (07R/25L) is used for passenger planes taking off and cargo flights due to its proximity to the cargo terminal. There are 49 frontal stands at the main passenger concourse, 28 remote stands and 25 cargo stands. There are also five parking bays at the Northwest Concourse. A satellite concourse with 10 frontal stands for narrow body aircraft has been commissioned to the north of the main concourse at the end of 2009, bringing the total number of frontal stands at the airport to 59. The airport was the busiest for passenger traffic in Asia in 2010, and the world's busiest airport for cargo traffic in 2010. In terms of international traffic, the airport is the third busiest for passenger traffic and the busiest for cargo since its operation in 1998. There are over 95 international airlines providing about 900 scheduled passenger and all-cargo flights each day between Hong Kong and some 160 destinations worldwide. About 76 percent of these flights are operated with wide-body jets. There is also an average of approximately 31 non-scheduled passenger and cargo flights each week. The operation of scheduled air services to and from Hong Kong is facilitated by air services agreements between Hong Kong and other countries.
