ABSTRACT
The preceding chapters have examined the evolution of Air Navigation Service Providers (ANSPs) around the world and the challenges they face as they look to the future. All ANSPs face the same basic tasks of providing separation between aircraft, both on the ground and in the air, so as to avoid collisions and providing efficient routing between the origin and destination of each flight. Prior to the 1987, almost all ANSPs were government agencies, including some that were part of the military, but since then there has been a widespread move toward commercialization under a range of organizational options.
