iiiForewordPurpose of the manual In September 1991, the Tenth Air Navigation Conferenceconsidered and endorsed a concept for a future air navi-gation system that would meet the needs of internationalcivil aviation over the next century. The concept, which wasdeveloped by the ICAO Future Air Navigation SystemsFANS Committee, came to be known as the communica-tions, navigation, and surveillance/air traffic managementCNS/ATM systems concept and involves a complex andinterrelated set of technologies, dependent, to a largedegree, on satellites.In follow-up of the work of the FANS Committee andthe Tenth Air Navigation Conference, several activities havetaken or are taking place within and through ICAO asfollowsthe Council of ICAO has acted on the recom-endations of the Tenth Air Navigation Conferenceto speed up the implementation of CNS/ATMthe global coordinated plan for transition to theCNS/ATM systems has been developedthe Air Navigation Commission is coordinatingtechnical activities leading to the development ofinternational Standards and RecommendedPractices SARPsseveral panels of the Air Navigation Commissionare developing the operational requirements andtechnical specifications necessary for implemen-tation of CNS/ATM systems institutional issues are being addressed by theCouncil of ICAO, the Legal Bureau and con-cerned States andregional planning groups are working on stra-tegies and analyses for their regions.The CNS/ATM systems concept has reached a highlevel of understanding and acceptance, and efforts are nowbeing directed at the implementation of a seamless, globalair traffic management system. In light of this, the globalplan mentioned above is being revised in a way that willpresent information of a practical nature to guide and assistStates, the ICAO Regional Offices, regional planninggroups, the avionics industry, and operators in planning forthe carriage of airborne equipment required for use withCNS/ATM systems.The primary objective of this manual is to guideairspace planners, ICAO Regional Offices and the regionalplanning groups and to assist them with implementation ofCNS/ATM systems, particularly in relation to airspaceplanning, implementation of the required navigationperformance RNP concept and area navigation techniques.This is in line with the objectives laid out by the Council ofICAO. It is envisioned that the airspace planning method-ology will become a part of a larger document dealing withimplementation issues.The methodology presented in this document providesa framework by which airspace characteristics, aircraftcapability and traffic demand can be assessed for thepurpose of determining safe separation minima for en-routeoperations. The methodology has been designed to ensurethat the intended safety level for a proposed airspace meetsthe required standard. Airspace planners will be able toassess different scenarios for airspace development.Administrations may use the methodology as a tool to assistthem in determining the sequence and nature of decisionsrequired to establish safe separation minima. However, it isrecognized that, in some cases, application of the method-ology may require risk analysis expertise which may not beavailable in all administrations. In these cases, furthertechnical advice and support should be obtained fromICAO. Relationship to otherICAO documentsExisting ICAO documents do not indicate methods forquantifying the effect a change of separation minima mayhave on air traffic safety. This document is intended for useby airspace planners as a basis for changing separationminima. It should be read in conjunction with the
