Planning for Performance Based Navigation: Airspace Concept and Implementation Processes Jeffrey T. Williams Manager, RNAV & RNP Group Air Traffic Organization U.S. Federal Aviation Administration

Overview PBN Snapshot: Components, Elements What is an Airspace Concept? Airspace Concept: Strategic Considerations Airspace Concept: Navigation Specifications by Domain Implementation Processes in the ICAO PBN Manual

Key Components RNAV RNP 104 137 65 RNAV - a method of navigation enabling aircraft to fly on any desired flight path within the coverage of referenced NAVAIDS or within the limits of the capability of self-contained systems, or a combination of these capabilities RNP is RNAV operations with the added feature of on-board navigation performance monitoring and alerting RNP 104 137 65

PBN Elements: A Snapshot Navigation Specification Navaid Infrastructure Application RNP RNAV PBN

What is an Airspace Concept? General Vision or Master Plan for particular airspace Geared towards Strategic Objectives Covers all elements of CNS/ATM PBN is only the “N” in CNS/ATM

Airspace Concept: Strategic Objective Considerations Safety? Capacity? Efficiency? Environment? Access? AIRSPACE CONCEPT COM NAV SUR ATM

Airspace Concept: Navigation Specifications By Domain (1) Oceanic & Remote Continental RNAV 10 (50/50) – e.g. Pacific RNP 4 (30/30) – e.g. Tasman Sea Continental En Route RNAV 5 – e.g. EUR Continental RNAV 2 – e.g. US Continental

Airspace Concept: Navigation Specifications By Domain (2) Terminal: Arrival and Departure RNAV 1 – EUR and US terminal airspace Basic RNP 1 – Future low density airspace Approach RNP APCH – US and EUR RNP AR APCH – US & various other

Implementation Processes ICAO PBN Manual – Doc 9613 (Revised) Process 1 – Determining Requirements Process 2 – Identifying ICAO Navigation Specification(s) for Implementation Process 3 – Planning and Implementation All 3 Processes need the combined efforts of regulators, service providers, users to be effective

Implementation Process 1 Determining Requirements Formulate Airspace Concept Assess Fleet Capability & NAVAID Infrastructure Assess Comm, Surveillance, ATM System Identify necessary navigation functions

Implementation Process 2 Identifying ICAO Navigation Specification(s) for Implementation Review ICAO Navigation Specifications Can fleet capability, CNS/ATM infrastructure support? If necessary, can trade-offs to requirements be made? Select ICAO Navigation Specification(s)

Implementation Process 3 Planning and Implementation Route / procedure placement, design, validation, pilot and controller training, automation implementation activities in 10 steps 1-Formulate Safety Plan 4-Design Review (Ground) 7-ATC System Integration 2- Validate Airspace Concept 5-Implementation Decision 8-Training/Awareness 3- Design Procedures/Routes 6-Flight Inspection/Validation 9-Implementation Date 10-Post Implementation Review
