What is an Airspace Concept?What is an Airspace Concept?

• General Vision or Master Plan for particular airspace

• Covers all elements of CNS/ATM

• Geared towards Strategic Objectives

PBN is only the “N” in CNS/ATM

Implementation ProcessesImplementation 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

Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 10

Implementation Process 1Implementation Process 1

Determining Requirements

• Formulate Airspace Concept

• Assess Fleet Capability & NAVAID Infrastructure

• Assess Comm, Surveillance, ATM System

• Identify necessary navigation functions

Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 11

Implementation Process 2Implementation Process 2

Identifying ICAO Navigation Specification(s)for Implementation

• Review ICAO Navigation Specifications

If necessary, can trade-offs to requirements be made?

• Select ICAO Navigation Specification(s)

Can fleet capability, CNS/ATM infrastructure support?
