Key Components
 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

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