A FUTURE SYSTEM FOR AIR TRANSPORT
The site selected for planning and evaluation was subjected to at least one iteration of preliminary engineering investigations, necessary to produce estimates of cost with any degree of reliability. Much is not yet known, but sufficient data have been gathered to devise a reasonable first order specification for an airport system.
The facility will provide initially for 160,000 to 240,000 annual transport aircraft operations and 20 to 30 million annual arriving and departing passengers. Attaining the upper ranges of these capacities will depend on anticipated technology and regulatory changes. Figure 10 compares the forecast demand with the capacity estimates for the new dual-lane airport and for Kai Tak. Based on the most probable forecast, a third runway may be needed in the early 1990s; if constructed, it would provide reserve capacity for many more years.
