Air passenger traffic in Asia-Pacific is forecast to grow at a rate of 4.6% 1per year. The estimated time to double is therefore about sixteen years. A fundamental challenge facing the aviation industry is to make investments to ensure that there is sufficient capacity to meet the projected demand. Network capacity is a systems concept and en-route air capacity can become a constraining factor. This could arise because of the limited air traffic control capacity of some Air Navigation Service Providers (ANSPs) to handle transit flights or because some air corridors become saturated to the point that only very uneconomic flight levels or undesirable time slots remain available.

In this project, we use the Balakrishnan and Chandra approach to build an analytical model of the existing ASEAN airspace calibrated with the current set of airline flights. The goal of the model is to allow the policy maker to scale the flight schedule tempo in selective, hypothetical ways to discover where and when bottlenecks arise. We develop the concept and model for the economic corridor capacity so as to ascertain the economic impact of existing and future capacities.
