Current RNAV Procedures in Japan
• Implemented 50NM lateral and longitudinal separation minima (based on RNP10) over NOPAC and CENPAC since 1998 and 2006, respectively
• Established three RNAV routes in 1992• Implemented 60 RNAV routes as of March 2007
Oceanic Airspace
En Route
• Established FMS arrival route in Tokyo (Haneda) in 1999• Expanded to five other airports since 2004
• Established RNAV (GNSS) approaches with Baro-VNAV at selected airports

Background
Growing traffic demands JCAB has predicted that air traffic in Japan will increase by
34 percent from 2005 to 2017 New runways at airports in Asia
Fuel savings and reduce noise
Reduce fuel, reduce emissions and reduce noise
High performance aircraft Increased number of aircraft equipped with multifunctional
FMS and GPS
Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 4
Capacity and Efficiency
Restructuring of ATS routes and airspace
Flexible use of airspace RNAV Reduction of separation
minima
Procedures
In order to accommodate growing traffic and increase efficiency, new capabilities should be introduced.
New capabilities will employ a combination of procedures and systems, such as a restructuring of ATS routes/airspace, and ATC support tools, which would increase controller capability and reduce workload.
New ATC workstations with controller support tools
Data link (ADS/CPDLC) GNSS

JCAB Initiatives
Developed “RNAV Roadmap for Japan” in April 2005.
Decided on an evolutionary implementation of RNAV procedures in Japan, and to continue working collaboratively with the operators on the implementation.
Established RNAV Implementation Team in October 2005 for implementing RNAV according to the RNAV Roadmap.
JCAB established a Steering Committee and Work Group in 2004 Composed of JCAB, operators, and aviation industry
representatives
The purpose was to review the current RNAV procedures, and develop an RNAV implementation plan for Japan

JCAB Study
4. Reviewed procedures currently available and identified procedures to be developed Certification, Operational Approvals, Design Criteria,
ATC Procedures, and Flight Inspection
2. Studied current and forecasted aircraft equipage
3. Studied airspace and infrastructure
1. Reviewed current operations (en route and terminal)
International Harmonization

RNAV Roadmap
Major issues considered International Harmonization
Increase capacity; Tokyo 4th Runway and Kansai 2nd Runway
Implementation Phase - 2007 : Introduction of internationally
harmonized procedures 2008 - 2012 : Increase capacity and efficient
operations 2013 - 2017, beyond : Future direction
Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 13
RNAV Roadmap - 1
Implement RNAV5 routes as an interim step for radar airspace
Operationally segregate between RNAV flights and VOR flights
Implement RNP2 routes, and expand RNP2 routes to non-radar airspace
Expect to mandate RNP2 above FL290
Reduce ATC complexity, Increase capacity, Improve efficiency

RNAV Roadmap - 2
Implement RNAV1 SID/STARs for radar airports
Airspace restructure at major airports
Implement RNP1 SID/STARs for non-radar airports
Expect to mandate RNP1 in mid-high density airports
Terminal
By 2009
RNAV will be available at major city pairs in Japan
from departure to arrival. By 2012
RNAV will be available at most of the airports in
Japan.
