ICAO 10063 PDF

SCOPE AND PURPOSE

This manual provides guidance and information to facilitate uniform application of Standards and Recommended Practices (SARPs) contained in Annex 6 — Operation of Aircraft, Annex 8 — Airworthiness of Aircraft, Annex 11 — Air Traffic Services, Annex 19 — Safety Management, the provisions in the Procedures for Air Navigation Services — Air Traffic Management (PANS-ATM) (Doc 4444) and, when necessary, the Regional Supplementary Procedures (Doc 7030).

This manual is intended to assist groups of States or regions in describing the functionality needed to monitor the safe application of performance-based horizontal separation minima in procedurally controlled airspace. The procedures for these separation minima apply performance-based navigation performance (PBN) contained in the Performance-based Navigation (PBN) Manual (Doc 9613) and performance-based communication and surveillance (PBCS) contained in the Performance-Based Communication and Surveillance (PBCS) Manual (Doc 9869).

The tasks as described in this manual for monitoring the application of performance-based horizontal separation minima may refer to system performance monitoring functions described in Doc 9869.

States may also call on the expertise developed for monitoring the application of performance-based horizontal separation minima, to assist in the implementation of new horizontal separation minima. Such an approach, in conjunction with performance-based specifications, such as for area navigation (RNAV), required navigation performance (RNP), required communication performance (RCP) and required surveillance performance (RSP), would assist in globally harmonizing the implementation and application of horizontal separation minima.

This manual applies to groups of States or regions applying performance-based horizontal separation minima in an en-route environment where procedural separation minima are being applied. It is not intended for operations in terminal airspace or en-route environments where ATS surveillance services are provided; any organization intent upon supporting safe operations in these environments should obtain safety-assessment and monitoring guidance elsewhere.

The manual is organized as follows:

a) Chapter 2 describes the functions necessary to monitor the application of performance-based horizontal separation minima by means of a list of duties and responsibilities;

b) Chapter 3 provides specific guidance on the duties and responsibilities that support implementation of performance-based horizontal separation minima;

c) Appendix A provides guidance on managing the status of performance-based operational approvals, and includes forms for collecting information, maintaining the information in electronic form and seeking clarification on operational approval status of an Operator;

d) Appendix B provides a form for an ATS unit to provide a monthly report of large lateral deviations (LLDs) and large longitudinal errors (LLEs);

e) Appendix C provides guidance for examining LLDs and LLEs;

f) Appendix D provides the traffic sample data (TSD) to collect and use to characterize the airspace and traffic movements;

g) Appendix E provides an example of an analysis that characterizes the airspace and traffic movements to support monitoring the application of performance-based horizontal separation minima;

h) Appendix F provides an overview of collision risk modeling assumptions when assessing the application of performance-based horizontal separation minima; and

i) Appendix G and Appendix H provide sample safety assessments for the application of performancebased horizontal separation minima.

This manual does not specify how the monitoring functions for applying performance-based horizontal separation minima are implemented by a group of States or region. The functions performed may be contained within a single organization or may be assigned to different working groups within the region. It is nevertheless recommended that the organization providing monitoring functions report directly to a regional safety oversight group tasked with monitoring overall system performance in light of regional safety goals. In turn, this safety oversight group will report to either the authorized Planning and Implementation Regional Group (PIRG) or the Regional Airspace Safety Group (RASG). For example, in the North Atlantic (NAT) Region, the North Atlantic Central Monitoring Agency (NAT CMA) reports to the NAT Safety Oversight Group (SOG), who is authorized by the NAT Systems Planning Group (SPG). In the Asia/Pacific (APAC) Region, several En-Route Monitoring Agencies (EMAs) report to the Asia/Pacific Regional Airspace Safety Monitoring Advisory Group (RASMAG), who reports to the Asia/Pacific Air Navigation Planning and Implementation Regional Group (APANPIRG).
