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

5. 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

7. 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

8. 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

9. 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

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

11. 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)

12. 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
