1. 1 Summary of day 4 Performance Based Navigation The symposium fully supports the PBN concept. It acknowledges that it addresses the States current and future operational requirements and therefore encourages ICAO, in coordination with all stakeholders, to accelerate its implementation. To this end the following goals and tasks are considered essential:

2. 2 Summary of day 4 Performance Based Navigation Implementation Goals: Efficiency: Enroute continental and terminal airspace PBN 100% implementation by 2018 Safety:APV for all runway ends Aerodromes for international use : 100% by 2016 Domestic Aerodromes: 100% by 2018

3. 3 Summary of day 4 Performance Based Navigation ICAO to maintain the PBN concept and coordinate new operational requirements ICAO to develop a PBN implementation strategy ICAO to take a pro-active role in assisting regions/sub regions and States

4. 4 Performance Hierarchy Initially defined in Global ATM Operational Concept Layers represent different views of the ATM system Allows tracing of performance impact Changes at lower levels impact next layer above Leads to expectations Helps understand and communicate performance case Level 1: Political and Socio-Economic Requirements Level 2: Expectations - RASP Level 3: ATM Component Functionality - RTSP Level 4: System Requirements (e.g., RNP, RCP) Level 5: Technologies (incl. standards, specifications) Summary of day 4

5. 5 A performance-driven approach to safety Requires Data Just Culture A measurement system Analysis capability Key Performance Indicators A fully functioning SMS Summary of day 4
