The estimation of runway capacity is important in airport planning and operational analysis. Standard procedures for capacity determination typically assume that there is no constraint on aircraft operations and do not provide good estimates when constraints exist. This paper presents a study of runway capacity at Singapore Changi Airport in which local operational constraints are taken into account. In addition, the impacts on capacity due to marine vessel crossings in a shipping channel near the airport, and the timing for implementation of simultaneous, independent instrument approach procedures are also investigated. The levels of annual aviation demand that could be served without excessive delays to aircraft under various operating scenarios are estimated.

The ground access system at Singapore Changi Airport is analyzed. The emphasis is on understanding traffic characteristics and utilization of access facilities. The applicability of typical ground access planning parameters recommended for western airports to Changi Airport is also investigated. Peak traffic levels are found to be manageable. The curbside is the critical link of the access system but congestion in peak periods do not last very long at present. Although the two public car parks together provide enough parking spaces, the closer-in car park is always full in the evening, while the cheaper car park is usually half empty even though it is only 250 m farther. This suggests convenience is more important than cost to most users.
