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
