Definition of Area Navigation (RNAV)
• 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
• RNAV operations achieve safety
through a combined use of
􀂃 aircraft navigation accuracy,
􀂃 air traffic control intervention
􀂾 via surveillance, communications
􀂃 route separation

Administration 4
• RNP is RNAV operations with
the added feature of on-board
navigation performance
monitoring and alerting
• RNP has the potential to allow
lessened reliance on air traffic
control intervention and/or route
separation to achieve the overall
safety of the operation

ICAO RNP Study Group
• ICAO formed the RNP Special Operations
Requirements Study Group (RNP Study Group) in
December 2003 to address the many confusing
usages of RNP and RNAV terms and concepts
􀂃 Members include Australia, Brazil, Canada,
EUROCONTROL, France, Japan, United Kingdom,
United States, IATA, ICCAIA, IFALPA
• RNP Study Group seeks global harmonization
covering standards and terminology
􀂃 Revised concept known as Performance Based
Navigation Concept (PBN); includes definitions of
RNAV and RNP
• Group revised ICAO Doc 9613, RNP Manual
􀂃 Renamed Performance-Based Navigation Manual
