GLOBAL AIR NAVIGATION PLAN FOR CNS/ATM SYSTEMS

Information Paper

SUMMARY

This paper introduces the Global Air Navigation Plan for CNS/ATM Systems, an updated and enhanced version of the Global Co-ordinated Plan for Transition to the ICAO CNS/ATM Systems. The revised Global Plan has been developed to include recently developed concepts and systems and has been expanded beyond its technical scope to include relevant economic, organizational, legal and technical co-operation issues. The Global Plan also includes a planning methodology intended to guide the regional planning groups in their implementation work.

1.	Introduction

1.1	Since the conclusion of the work of the Special Committee on Future Air Navigation Systems (FANS) in October 1993, ICAO and the other partners have significantly progressed the development of material, concepts and systems necessary for planning, implementation and operation of CNS/ATM systems.

1.2	As technology advances, however, new systems and concepts continue to emerge offering potential improvements in terms of safety, efficiency and/or economy of international flights. The Global Air Navigation Plan for CNS/ATM Systems (Global Plan), which is an updated and enhanced version of the Global Co-ordinated Plan for Transition to the ICAO CNS/ATM Systems, has been developed to include recently developed concepts and systems. The Global Plan has also been expanded beyond its technical scope to include relevant economic, organizational, legal and technical co-operation issues.

1.3	One of the objectives of the Global Plan is to define and illustrate ICAO's process for CNS/ATM systems planning and implementation as a logical consequence of the work already accomplished. This includes an analysis of the structured relationship between the global, regional and national planning processes as well as the relationship with other ICAO planning activities. The Global Plan also offers background information on the different elements and entities involved in CNS/ATM systems planning and implementation with the goal of creating, within one document, a nucleus of information necessary to facilitate the move towards the next phase of CNS/ATM planning and implementation. At the same time the Global Plan attempts to bring up to date, in a consolidated format, the progress generally achieved by the regions and illustrates, with appropriate timelines, the work remaining, forming the implementation schedule for the future.

1.4	The Global Plan has been developed so that it has a clear and functional relationship with the regional air navigation plans (ANPs). This has been accomplished by dividing the Global Plan into two volumes. Volume I, Operational Concept and General Planning Principles will guide further development of the Basic Operational Requirements and Planing Criteria of the regional ANPs. Volume II of the Global Plan reflects more detailed material and relates to the Facilities and Services Implementation Documents (FASIDs) used in the regional planning process.

1.5	Volumes I and II together provide the means for a step-by-step approach to planning for implementation of global CNS/ATM systems. To begin the process, several homogeneous ATM areas and major traffic flows have been identified in Volume II. The tables that follow in Volume II were generated with the purpose of assisting the planning and implementation regional groups (PIRGs) in further identifying the inter-regional CNS/ATM systems infrastructure necessary to support the implementation of homogeneous ATM areas and major traffic flows.

1.6	Volume II of the Global Plan depicts the facilities and services to be provided to satisfy the requirements for implementation of global CNS/ATM systems. The document is amended to reflect changes in facilities and/or services emanating from regional type air navigation meetings or through the amendment procedure described in the regional ANPs. The information in this document, therefore, largely reflects what has been agreed to through the regular regional planning processes. This document will serve the purpose of clearly identifying the inter-regional CNS/ATM systems infrastructure necessary to support the implementation of global CNS/ATM systems while serving as an executive register of the progress achieved by the PIRGs and the work remaining.

2.	Conclusions

2.1	The emerging technologies will support a variety of systems designs and implementation options. The challenge for the planner and designer is to develop an adequate understanding of the costs, benefits and operational suitability of these alternatives while considering the legal, organizational and financial aspects. Based on this, planners and designers will orchestrate a co-ordinated programme of ATM improvements that takes into account user needs, their willingness to upgrade their capabilities to achieve operational benefits, and also to pay for the changes required by ATM service providers. This revised Global Plan is intended to guide the international aviation community toward meeting this challenge and implementing CNS/ATM systems.
