In the United States and in Europe, there is the need to protect non-utilized exiting airport infrastructure (both civil and military airports) that can later be used to accommodate demand through the emergence of secondary airports. In parts of Asia where the existing under-utilized airport infrastructure is weak and where projections of high volume of demand -with high uncertainty- are high, there is the need to apply a dynamic approach to develop multi-airport systems. This approach includes actions such as reserving land area for future airport development and keeping original airports open since this option has proven to be useful and successful in the other regions of the world (i.e. United States and Europe). In some parts of Asia, such as India, where the military airport infrastructure is more developed than in other parts, there is also the need, as in the United States and Europe, to protect these airports since they may become future secondary airports following the airport status conversion dynamics that were observed in Europe.
