ABSTRACT
This chapter deals with communications, navigation and surveillance/air traffic management (CNS/ATM) evolution and transition issues. It identifies critical transition events and addresses several key issues in terms of the human element, equipment and facilities, operations and costs involved. The chapter describes the Global Plan, a document that was produced by the Future Air Navigation System Committee. The transition to new CNS systems should be based on improvements in ATM, and should be accompanied by structural and procedural changes that will enhance ATM and provide benefits to users. Planning and implementation of improved ATM capabilities should include consideration of human factors impacts and requirements. Training requirements associated with new technologies are an essential concern, especially for less developed States. The action programme for transition to and implementation of the new CNS/ATM systems includes guidelines and key activities for the States/regions, users, service providers, and International Civil Aviation Organization.
